74AHC594; 74AHCT594
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.
Features
- Balanced propagation delays
- All inputs have Schmitt-trigger actions
- Inputs accept voltages higher than VCC
- 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 JESD78 Class II
- Input levels:
- For 74AHC594: CMOS level
- For 74AHCT594: TTL level
- ESD protection:
- HBM EIA/JESD22-A114E exceeds 2000 V
- MM EIA/JESD22-A115-A exceeds 200 V
- CDM EIA/JESD22-C101C exceeds 1000 V
- Multiple package options
- Specified from -40 Cel to +85 Cel and from -40 Cel to +125 Cel
