M54/M74HC192 M54/M74HC193 HC192 - SYNCHRONOUS UP/DOWN DECADE COUNTER HC193 - SYNCHRONOUS UP/DOWN BINARY COUNTER HIGH SPEED fMAX = 54 MHz (TYP.) AT VCC = V LOW POWER DISSIPATION ICC = µA (MAX.) AT TA = 25 °C HIGH NOISE IMMUNITY VNIH = VNIL = 28 % VCC (MIN.) OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = mA (MIN.) BALANCED PROPAGATION DELAYS tPLH = tPHL WIDE OPERATING VOLTAGE RANGE VCC (OPR) = V TO V PIN AND FUNCTION COMPATIBLE WITH 54/74LS192-193 DESCRIPTION The M54/74HC192/193 are ahigh speed CMOSSYNCHRONOUS UP/DOWN DECADE COUNTERS fabricated in silicon gate C2MOS technology They have the same high speed performance of LSTTL combined with true CMOS low power consumption The counter has two separate clock inputs, an UP COUNT input and a DOWN COUNT input All outputs of the flip-flop are simultaneously triggered on the low to high transition of either clock while the other input isheld high The direction of counting is determined by which input is clocked This counter may be preset by entering the desired data on the DATA A, DATA B, DATA C, and DATA D input When the LOAD input is taken low the data is loaded independently of either clock input This feature allows the counters to be used as divide-by-n counters by modifying the count length with the preset inputs In addition the counter can also be cleared This is accomplished by inputting a high on the CLEAR input All internal stages are set to low independently of either COUNT input Both a BORROW and CARRY output are provided to enable cascading of both up and down counting functions The BORROW output produces a negative going pulse when the counter underflows and the CARRY outputs a pulse when the counter overflows The counter can be cascaded by connecting the CARRY and BORROW outputs of one device to the COUNT UP and COUNT DOWN inputs, respectively, of the next device All inputs are equipped with protection circuits against static discharge and transient excess voltage October 1992 B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HCXXXF1R M74HCXXXM1R M74HCXXXB1R M74HCXXXC1R PIN CONNECTIONS (top view) NC = No Internal Connection 1/15 M54/M74HC192/193 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 3, 2, 6, QA to QD CPD Flip-Flop Outputs Count Down Clock Input LOAD 12 CARRY 13 BORROW 14 CLEAR 15, 1, 10, DA to DD GND 16 IEC LOGIC SYMBOL (HC191) CPU 11 VCC Count Up Clock Input Asynchronous Parallel Load Input (Active LOW) Count Up (Carry) Output (Active LOW) Count Down (Borrow) Output (Active LOW) Asynchronous Reset Input (Active HIGH) Data Inputs Ground (0V) Positive Supply Voltage IEC LOGIC SYMBOL (HC193) TRUTH TABLE COUNT UP COUNT DOWN H LOAD H CLEAR L FUNCTION COUNT UP H H L NO COUNT H H L L COUNT DOWN NO COUNT H H X X L L PRESET X X X H RESET X: Don’t Care 2/15 M54/M74HC192/193 LOGIC DIAGAM (HC192) 3/15 M54/M74HC192/193 LOGIC DIAGAM (HC193) 4/15 M54/M74HC192/193 TIMING DIAGRAM (HC192) TIMING DIAGRAM (HC193) 5/15 M54/M74HC192/193 ABSOLUTE MAXIMUM RATINGS Symbol Value Unit VCC VI Supply Voltage DC Input Voltage -0.5 to +7 -0.5 to VCC + 0.5 V V VO DC Output Voltage -0.5 to VCC + 0.5 V IIK IOK DC Input Diode Current DC Output Diode Current ± 20 ± 20 mA mA IO DC Output Source Sink Current Per Output Pin ± 25 mA DC VCC or Ground Current ± 50 mA 500 (*) mW ICC or IGND Parameter PD Power Dissipation Tstg TL Storage Temperature Lead Temperature (10 sec) -65 to +150 300 o o C C Absolute Maximum Ratings are those values beyond which damage to the device may occur Functional operation under these condition isnotimplied (*) 500 mW: ≅ 65 oC derate to 300 mW by 10mW/oC: 65 oC to 85 oC RECOMMENDED OPERATING CONDITIONS Symbol VCC Parameter Value to VI Input Voltage VO Top Output Voltage Operating Temperature: M54HC Series M74HC Series Input Rise and Fall Time tr, tf VCC = V Unit V to VCC Supply Voltage V to VCC -55 to +125 -40 to +85 to 1000 V C o C ns VCC = 4.5 V 6/15 to 500 VCC = V to 400 o M54/M74HC192/193 DC SPECIFICATIONS Test Conditions Symbol VIH V IL Parameter High Level Input Voltage Low Level Input Voltage Value VCC (V) TA = 25 oC 54HC and 74HC Min Typ Max 2.0 1.5 1.5 1.5 4.5 6.0 3.15 4.2 3.15 4.2 3.15 4.2 High Level Output Voltage 0.5 0.5 0.5 4.5 1.35 1.35 1.35 2.0 4.5 6.0 4.5 VOL Low Level Output Voltage 6.0 2.0 4.5 6.0 4.5 6.0 II ICC Input Leakage Current Quiescent Supply Current Unit V 2.0 6.0 V OH -40 to 85 oC -55 to 125 oC 74HC 54HC Min Max Min Max 6.0 6.0 1.8 1.8 V 1.8 1.9 2.0 1.9 1.9 VI = IO=-20 µA VIH or V IL IO=-4.0 mA 4.4 5.9 4.5 6.0 4.4 5.9 4.4 5.9 4.18 4.31 4.13 4.10 IO=-5.2 mA 5.68 5.8 0.0 5.63 5.60 V VI = IO= 20 µA VIH or V IL IO= 4.0 mA 0.1 0.1 0.1 0.0 0.1 0.1 0.1 0.0 0.17 0.1 0.26 0.1 0.33 0.1 0.40 IO= 5.2 mA 0.18 V 0.26 0.33 0.40 VI = VCC or GND ±0.1 ±1 ±1 µA VI = VCC or GND 40 80 µA 7/15 M54/M74HC192/193 AC ELECTRICAL CHARACTERISTICS (C L = 50 pF, Input t r = tf = ns) Test Conditions TA = 25 oC 54HC and 74HC Value -40 to 85 oC -55 to 125 oC 74HC 54HC Symbol Parameter VCC (V) tTLH tTHL Output Transition Time 2.0 4.5 Typ 30 Max 75 15 tPLH tPHL Propagation Delay Time (UP, DOWN -
