MC74HC157A
Quad 2âInput Data
Selectors / Multiplexers
HighâPerformance SiliconâGate 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.
Features
⢠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
⢠PbâFree Packages are Available*
