ON MC74HC157AN

数据选择器/多路复用器4 x 2：12V ~ 6V

Overview

Quad 2−Input Data Selectors / Multiplexers   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 µA• 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
