SN54/74LS253
DUAL 4-INPUT MULTIPLEXER
WITH 3-STATE OUTPUTS
The LSTTL / MSI SN54 / 74LS253 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 DUAL 4-INPUT MULTIPLEXER
with a HIGH on the respective Output Enable (E0) inputs, allowing the outputs WITH 3-STATE OUTPUTS
to interface directly with bus oriented systems. It is fabricated with the
Schottky barrier diode process for high speed and is completely compatible LOW POWER SCHOTTKY
with all Motorola TTL families.
