74AHC257 Description
The 74AHC/AHCT257 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/AHCT257 has four identical 2-input multiplexers with 3-state outputs, which select 4 bits of QUICK REFERENCE DATA GND = 0.
74AHC257 Key Features
- Balanced propagation delays
- All inputs have Schmitt-trigger actions
- Non-inverting data path
- Inputs accept voltages higher than VCC
- For AHC only: operates with CMOS input levels
- For AHCT only: operates with TTL input levels
