Part Number : 74HC157
Function : High-Speed CMOS Logic Quad 2-Input Multiplexer
Package : DIP, SOIC 16 Pin
Manufacturers : Texas Instruments
The ’74HC157, ’74HCT157, ’74HC158, and ’74HCT158 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select input (S).
The Enable input (E) is active Low. When (E) is High, all of the outputs in the 158, the inverting type, (1Y-4Y) are forced High and in the 157, the non-inverting type, all of the outputs (1Y-4Y) are forced Low, regardless of all other input conditions.
1. Common Select Inputs
2. Separate Enable Inputs
3. Buffered inputs and Outputs
4. Balanced Propagation Delay and Transition Times
5. Significant Power Reduction Compared to LSTTL Logic ICs
