SN74HC157DBR – TEXAS INSTRUMENTS

The SN74HC157DBR is a high-speed 4-to-1 data selector/multiplexer from the HC CMOS family designed for efficient signal routing in digital systems. Operating over a supply voltage range of 2 V to 6 V, this device offers typical propagation delays in the range of 10–15 ns, ensuring rapid data selection with minimal distortion. It provides four independent data paths with a single common select input, making it ideal for applications such as bus switching, memory addressing, and interface control between microprocessors and peripherals. With low static power consumption and high noise immunity, the SN74HC157DBR is suited for high-density PCB designs in both consumer and industrial applications. Detailed datasheet specifications include defined voltage thresholds, output drive capabilities, and low power dissipation characteristics. Engineers appreciate its robust performance, ease of integration with other logic families, and predictable switching behavior, which together contribute to improved system reliability and signal integrity in complex digital environments.
