TECHNICAL DATA
IN74HC253A
Dual 4-Input Data Selector/Multiplexer with 3-State Otputs
High-Performance Silicon-Gate
CMOS
The IN74HC253A is identical in pinout to the LS/ALS253.
The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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.
• Outputs Directly Interface to
CMOS, NMOS, and TTL • Operating
Voltage Range: 2.
0 to 6.
0 V • Low Input Current: 1.
0 µA • High Noise Immunity Characteristic of
CMOS Devices
