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 completely compatible with all ON Semiconductor TTL families.
