High–Performance Silicon–Gate CMOS
The 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
