74AHCT594 Datasheet | NXP Semiconductors

description The 74AHC594; 74AHCT594 is a high-speed Si-gate CMOS device and is pin patible with Low-Power Schottky TTL (LSTTL). It is specified in pliance 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.
