CD54ACT273 - Octal D Flip-Flop

Download the CD54ACT273 datasheet PDF. This datasheet also covers the CD54AC273 variant, as both devices belong to the same octal d flip-flop family and are provided as variant models within a single manufacturer datasheet.

General Description

The ’AC273 and ’ACT273 devices are octal D-type flip-flops with reset that utilize advanced CMOS logic technology.

Information at the D input is transferred to the Q output on the positive-going edge of the clock pulse.

All eight flip-flops are controlled by a common clock (CP) and a common reset (MR).

Key Features

  • Buffered Inputs.
  • Typical Propagation Delay - 6.5ns at VCC = 5V, TA = 25oC, CL = 50pF.
  • Exceeds 2kV ESD Protection MIL-STD-883, Method 3015.
  • SCR-Latchup-Resistant CMOS Process and Circuit Design.
  • Speed of Bipolar FAST™/AS/S with Significantly Reduced Power Consumption.
  • Balanced Propagation Delays.
  • AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply.
  • ±24mA Output Drive Current - Fanout to 15.
