74AHC594; 74AHCT594 8-bit shift register with output register Rev. 3 — 25 June 2020 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. 7-A. 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 and benefits • Wide supply voltage range from 2.0 V to 5.5 V • Balanced propagation delays • All inputs have Schmitt-trigger action • Overvoltage tolerant inputs to 5.5 V • High noise immunity • CMOS low power dissipation • 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 Level A • Input levels: • For 74AHC594: CMOS level • For 74AHCT594: TTL level • ESD protection: • HBM JESD22-A114F exceeds 2000 V • MM JESD22-A115-A exceeds 200 V • CDM JESD22-C101E exceeds 1000 V • Multiple package options • 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
