Data Selector/Multiplexer (Mux), 2-Input Q

Favorite

Overview

High-Performance Silicon-Gate CMOS

The MC74HC157A is identical in pinout to the LS157. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in noninverted form. A high level on the Output Enable input sets all four Y outputs to a low level.

  • Output Drive Capability: 10 LSTTL Loads
  • Outputs Directly Interface to CMOS, NMOS, and TTL
  • Operating Voltage Range: 2.0 to 6.0 V
  • Low Input Current: 1.0 mA
  • High Noise Immunity Characteristic of CMOS Devices
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7A
  • Chip Complexity: 82 FETs or 20.5 Equivalent Gates
  • Pb-Free Packages are Available*
