TC74HCT157AP — TTL-compatible & fast ~21 ns switching.

TC74HCT157AP is a Toshiba quad 2-input multiplexer that selects four bits from two sources under one select line. The enable pin forces all outputs LOW when HIGH, giving simple gating and bus control. TC74HCT157AP accepts TTL/NMOS/CMOS levels, runs on 4.5–5.5 V, and delivers about 21 ns propagation with only ~4 µA ICC. Outputs are non-inverting and can drive typical LSTTL loads, making TC74HCT157AP a solid choice for data routing, function generation, and mixed-logic interfaces.
