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 3-STATE OUTPUTS  
with a HIGH on the respective Output Enable (E ) inputs, allowing the outputs  
0
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 Motorola TTL families.
