8-Bit Shift Register/Latch (3-state)

The TC74HC595A is a high speed 8-BIT SHIFT

REGISTER/LATCH fabricated with silicon gate C2MOS

technology.

It achieve the high speed operation similar to equivalent

LSTTL while maintaining the CMOS low power dissipation.

The TC74HC595A contains an 8-bit static shift register which

feeds an 8-bit storage register.

Shift operation is accomplished on the positive going transition

of the SCK input. The output register is loaded with the contents

of the shift register on the positive going transition of the RCK

input. Since RCK and SCK signal are independent, parallel

outputs can be held stable during the shift operation.

And, since the parallel outputs are 3-state, it can be directly

connected to 8-bit bus. This register can be used in

serial-to-parallel conversion, data receivers, etc.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
