74F253SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F253SCX is a dual 4-input multiplexer with 3-STATE outputs housed in a 16-Lead Small Outline Integrated Circuit (SOIC) package. It selects two bits of data from four sources using common select inputs S0 and S1. The device operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. Propagation delays are specified at 8.5 ns maximum for Select-to-Output transitions and 7.0 ns maximum for Input-to-Output transitions under standard conditions.
