74AHC(T)594

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.

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

Target applications

  • Serial-to parallel data conversion
  • Remote control holding register
