Product Overview
The SN74F157ADR is a high-speed quad 2-input multiplexer from Texas Instruments, designed for data routing and selection in digital systems. It operates from a 4.5V to 5.5V supply and features Schottky-clamped transistors for fast switching. The device selects one of two 4-bit data sources based on the select input (A/B) and provides the selected data at the outputs. The enable input (G) can be used to force all outputs low for bus isolation. Packaged in a 16-SOIC, it is ideal for space-constrained applications.
