The MC74LCX32 is a high performance, quad 2–input OR gate
operating from a 2.7 to 3.6V supply. High impedance TTL compatible
inputs significantly reduce current loading to input drivers while TTL
compatible outputs offer improved switching noise performance. A V

I

specification of 5.5V allows MC74LCX32 inputs to be safely driven from
5V devices.

Current drive capability is 24mA at the outputs.

• Designed for 2.7 to 3.6V V

CC

Operation

• 5V T olerant Inputs — Interface Capability With 5V TTL Logic

* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or

conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute–maximum–rated conditions is
not implied.
