74AHC594; 74AHCT594

8-bit shift register with output register

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.

特性

  • 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: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C

目标应用

  • Serial-to parallel data conversion

  • Remote control holding register
