SN74AHC574 (ACTIVE) Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs

 

Description

The SNx4AHC574 devices are octal edge-triggered D-type flip-flops that feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. These devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Features

  • Operating Range 2-V to 5.5-V VCC
  • 3-State Outputs Drive Bus Lines Directly
  • Latch-Up Performance Exceeds 250 mA
    Per JESD 17
  • On Products Compliant to MIL-PRF-38535,
    All Parameters Are Tested Unless Otherwise
    Noted. On All Other Products, Production
    Processing Does Not Necessarily Include
    Testing of All Parameters.
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model
    • 200-V Machine Model
    • 1000-V Charged-Device Model
