MM54HC595 MM74HC595 8-Bit Shift Registers with Output Latches General Description Features This high speed shift register utilizes advanced silicon-gate CMOS technology This device possesses the high noise immunity and low power consumption of standard CMOS integrated circuits as well as the ability to drive 15 LS-TTL loads This device contains an 8-bit serial-in parallel-out shift register that feeds an 8-bit D-type storage register The storage register has TRI-STATE outputs Separate clocks are provided for both the shift register and the storage register The shift register has a direct-overriding clear serial input and serial output (standard) pins for cascading Both the shift register and storage register use positive-edge triggered clocks If both clocks are connected together the shift register state will always be one clock pulse ahead of the storage register The 54HC 74HC logic family is speed function and pin-out compatible with the standard 54LS 74LS logic family All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground Y Connection Diagram Truth Table Dual-In-Line Package Y Y Y Y Y Y Low quiescent current

used when designing with this supply Worst case VIH and VIL occur at VCC e 5V and 5V respectively (The VIH value at 5V is 85V ) The worst case leakage current (IIN ICC and IOZ) occur for CMOS at the
