M74HC595 Datasheet (ST Microelectronics)

M74HC595, 8-bit shift register

The M74HC595 device is a high speed CMOS 8-bit shift register with output latches (3-state) fabricated with silicon gate C2MOS technology.

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 8 3-state outputs.

M74HC595 Features

* High speed: fMAX = 59 MHz (typ.) at VCC = 6 V

* Low power dissipation: ICC = 4 μA (max.) at TA= 25 °C

* High noise immunity: VNIH = VNIL = 28% VCC (min.)

* Symmetrical output impedance:

* |IOH| = IOL = 6 mA (min.) for QA to QH

* |IOH| = IOL = 4 mA (m
