74AHC594; 74AHCT594

8-bit shift register with output register

Rev. 01 — 4 July 2006

Product data sheet

1. General description

The 74AHC594; 74AHCT594 is a high-speed Si-gate CMOS device and is pin compatible

with Low-Power Schottky TTL (LSTTL). It is speciﬁed in compliance with JEDEC standard

No. 7A.

The 74AHC594; 74AHCT594 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

■ Wide supply voltage range from 2.0 V to 5.5 V

■ 8-bit serial-in, parallel-out shift register with storage

■ Independent direct overriding clears on shift and storage registers

■ Independent clocks for shift and storage registers

■ Latch-up performance exceeds 100 mA per JESD 78 Class II

■ Input levels:

◆ CMOS levels: 74AHC594 only

◆ TTL levels: 74AHCT594 only

■ ESD protection:

◆ HBM JESD22-A114-C exceeds 2000 V

◆ MM JESD22-A115-A exceeds 200 V

◆ CDM JESD22-C101-C exceeds 1000 V

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

3. Applications

■ Serial-to parallel data conversion

■ Remote control holding register
