CD74ACT253 - Dual 4-Input Multiplexer

Download the CD74ACT253 datasheet PDF. This datasheet also covers the CD74AC253 variant, as both devices belong to the same dual 4-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

The CD74AC253 and ’ACT253 dual 4-input multiplexers that utilize Advanced CMOS Logic technology.

One of the four sources for each section is selected by the common Select inputs, S0 and S1.

When the Output Enable (1OE or 2OE) is HIGH, the output is in the high-impedance state.

Key Features

  • Buffered Inputs.
  • Typical Propagation Delay - 6.3ns 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.
