Part Number : MC74HC157A
Function : Quad 2-Input Data Selectors / Multiplexers
Manufacturers : ON Semiconductor
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 A
•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
•NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
•These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
