MC74HC253N
Dual 4-Input Data Selector/Multiplexer with 3-State Outputs
SEMICONDUCTOR TECHNICAL DATA -
" !
High–Performance Silicon–Gate CMOSThe MC74HC253 is identical in pinout to the LS253. The device inputs are
compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
The Address inputs select one of four Data inputs from each multiplexer.
Each multiplexer has an active–low Output Enable control and a three–state
noninverting output.
The HC253 is similar in function to the HC153 which does not have
three–state outputs. Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 μA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard
