FAST AND LS TTL DATA
DUAL 4-INPUT MULTIPLEXER
WITH 3-STATE OUTPUTS
The LSTTL/MSI SN54/74LS353 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 Schott-
ky barrier diode process for high speed and is completely compatible with all
TTL families.
