SN74LS253 Dual 4-Input Multiplexer

The LS253 contains two identical 4-Input Multiplexers with 3-state outputs. They select two bits from four sources selected by common select inputs (S0, S1). The 4-input multiplexers have individual Output Enable (E0a, E0b) inputs which when HIGH, forces the outputs to a high impedance (high Z) stat.

SN74LS253 Dual 4 Input Multiplexer with 3 State Outputs The LSTTL / MSI SN74LS253 is a Dual 4-Input Multiplexer with 3-state outputs. It can select two bits of data from four sources using common select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (E0) inputs, allowing the outputs to interface directly with bus oriented systems. It is fabricated with the Schottky barrier diode process for high speed and is.
