U74AHCT157 - QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR/MULTIPLEXER

General Description

The U74AHCT157 is a quadruple 2-line to 1-line data selector/multiplexer.

When G is high, all outputs are low.

When G is low, a 4-bit word is selected from one of two sources and is routed to the four outputs.

Key Features

  • S.
  • TTL-Voltage Compatible.
  • Max tPD of 4.1ns from A or B to Y at 5V, CL=15pF.
  • Low Quiescent Current: ICC = 2 μA (MAX) at 5.5V.
  • ±8 mA output driver at 5V CMOS IC.
