The 74LS157AN is a quad 2-to-1 multiplexer/demultiplexer designed using Low Power Schottky (LS) TTL technology . It is part of the popular 74LS series of logic ICs, which are widely used in digital systems for their balance of speed, power efficiency, and reliability.
Specification
- Quad 2-to-1 Multiplexer/Demultiplexer :
- The 74LS157AN contains four independent 2-to-1 multiplexers, each capable of selecting one of two input signals based on a common select line.
- Common Select Input :
- All four multiplexers share a single Select (S) input, allowing simultaneous switching of all channels.
- 3-State Outputs :
- The outputs can be placed in a high-impedance (high-Z) state when the Enable (E) input is activated. This feature is critical for bus-oriented systems where multiple devices share the same data lines.
- TTL-Compatible Inputs and Outputs :
- The 74LS157AN is fully compatible with other TTL logic families, making it easy to integrate into existing digital systems.
- Low Power Consumption :
- Built using Low Power Schottky (LS) technology, this IC offers reduced power consumption compared to standard TTL devices while maintaining fast switching speeds.
- High-Speed Operation :
- The propagation delay is typically around 15ns, making it suitable for high-speed digital applications.
