Technical Details & Description

Quad 2:1 mux with 32/64 mA drive

The CY74FCT157CTSOC is a quad 2-input multiplexer from the 74FCT family, routing one of two data sources per channel to the output based on a common select line. Each of the four multiplexers selects between two inputs, giving a 4 x 2:1 configuration in a single 16-SOIC package. Output drive is rated at 32 mA source and 64 mA sink — enough to drive a standard TTL load or a short PCB trace without a buffer.

Board-fit and sourcing posture

The surface-mount assembly matches reflow profiles common to lead-free solder processes.
