74HCT157
Quad 2−Input Data
Selectors / Multiplexers
High−Performance Silicon−Gate CMOS
The 74HCT157 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
• TTL/NMOS−Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 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
• ESD Performance: HBM > 2000 V; Machine Model > 200 V
• Chip Complexity: 82 FETs or 20.5 Equivalent Gates
• These are Pb−Free Devices
