74HC257 Description
The 74HC/HCT257 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 74HC/HCT257 have four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and are controlled by a mon data select input (S).
74HC257 Key Features
- Non-inverting data path
- 3-state outputs interface directly with system bus
- Output capability: bus driver
- ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT257 are high-speed Si-gate CMOS devices and are pin patible with low p
