SN54HC574 - OCTAL EDGE-TRIGGERED D-TYPE FLIP-FLOP

General Description

These octal edge-triggered D-type flip-flops feature 3-state outputs designed specifically for bus driving.

They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Key Features

  • Wide Operating Voltage Range of 2 V to 6 V.
  • High-Current 3-State Noninverting Outputs Drive Bus Lines Directly or Up to 15 LSTTL Loads.
  • Low Power Consumption, 80-µA Max ICC.
  • Typical tpd = 22 ns.
  • ±6-mA Output Drive at 5 V.
  • Low Input Current of 1-µA Max.
  • Bus-Structured Pinout.
  • On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessa.
