The 74HC258N / 74HCT258 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT258 have four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and are controlled by a common data select input (S). The data inputs from source 0 (1I0 to 4I0) are selected when input S is LOW and the data inputs from source 1(1I1 to 4I1) are selected when S is HIGH.
1. Inverting data path
2. 3-state outputs interface directly with system bus
3. Output capability: bus driver
4. ICC category: MSI.
