8-bit shift register with output register

Rev. 03 — 20 December 2006

Product data sheet

1. General description

The 74HC594; 74HCT594 is a high-speed Si-gate CMOS device and is pin compatible

with Low-Power Schottky TTL (LSTTL).

The 74HC594; 74HCT594 is an 8-bit, non-inverting, serial-in, parallel-out shift register that

feeds an 8-bit D-type storage register. Separate clocks (SHCP and STCP) and direct

overriding clears (SHR and STR) are provided on both the shift and storage registers.

A serial output (Q7S) is provided for cascading purposes.

Both the shift and storage register clocks are positive-edge triggered. If the user wishes to

connect both clocks together, the shift register will always be one count pulse ahead of the

storage register.

2. Features

I Synchronous serial input and output

I Complies with JEDEC standard No.7A

I 8-bit parallel output

I Shift and storage registers have independent direct clear and clocks

I Independent clocks for shift and storage registers

I 100 MHz (typical)

I Multiple package options

I Specified from −40 °C to +85 °C and from −40 °C to +125 °C

3. Applications

I Serial-to parallel data conversion

I Remote control holding register
