74HC157; 74HCT157
Applications
Digital multiplexers allow a number of inputs to be independently switched to a single output. Nexperia's digital multiplexers are available in multiple logic families with one digital output connecting to one of 2, 4 or 8 input lines based on the digital code present at control inputs. Some multiplexers also offer complimentary outputs.
Digital multiplexers are available in standard SO, TSSOP and innovative leadless DQFN packages for PCB space saving. Nexperia's digital multiplexers are fully specified from -40 ºC to 125 ºC.
Features and benefits
- Mixed 5 V and 3.3 V applications
- Bus width reduction
- High noise immunity
- Low power consumption
- Wide supply voltage range
- Low propagation delay
- Overvoltage tolerant input options
- Complementary output options
