74AHC157 Overview
74AHCT157 The 74AHC/AHCT157 are high-speed Si-gate CMOS devices and are pin patible with low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard No. The 74AHC/AHCT157 are quad 2-input multiplexers which select 4 bits of data from two sources under the control of a mon data select input (S).
74AHC157 Key Features
- Balanced propagation delays
- All inputs have Schmitt-trigger actions
- Multiple input enable for easy expansion
- Ideal for memory chip select decoding
- Inputs accept voltages higher than VCC
- For AHC only: operates with CMOS input levels
- For AHCT only: operates with TTL input levels
