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
