74F253 Description
The 74F253 has two identical 4-input multiplexers with 3-State outputs which select two bits from four sources selected by mon Select inputs (S0, S1). When the individual Output Enable (OEa, OEb) inputs of the 4-input multiplexers are High, the outputs are forced to a high impedance (Hi-Z) state. The 74F253 is the logic implementation of a 2-pole, 4-position switch;.
74F253 Key Features
- 3-State outputs for bus interface and multiplex expansion
- mon select inputs
- Separate Output Enable Inputs
