1. General description
2. Features
3. Applications
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.
