Product details

Quad 2:1 multiplexer, 74LVC family

The SN74LVC257AD is a quad 2:1 multiplexer from Texas Instruments' 74LVC logic family. It selects one of two 4-bit data inputs per channel, routing the chosen data to the output based on a common select line. Output drive is rated 24 mA source and 24 mA sink, sufficient for driving light loads or multiple downstream CMOS inputs within the same voltage domain.

RoHS3 compliant (2011/65/EU + 2015/863), with no exemptions listed. The part is lead-free and suitable for RoHS-driven BOMs.
