74HCT173 - Quad D-Type Flip-Flop

Download the 74HCT173 datasheet PDF. This datasheet also covers the 74HC173 variant, as both devices belong to the same quad d-type flip-flop family and are provided as variant models within a single manufacturer datasheet.

Description

The CDx4HC173 and CDx4HCT173 contains four independent D-type flip-flops with shared clock (CP), reset (MR), and data enable (E1, E2) pins.

Features

  • Three-state buffered outputs.
  • Gated input and output enables.
  • Fanout (over temperature range).
  • Standard outputs : 10 LSTTL loads.
  • Bus driver outputs : 15 LSTTL loads.
  • Wide Operating Temperature Range : -55°C to 125°C.
  • Balanced propagation delay and transition times.
  • Significant power and reduction compared to LSTTL logic ICs.
  • HC types.
  • 2 V to 6 V operation.
  • High noise immunity: NIL = 30%, NIH = 30.
