MC74LCX32
Low-Voltage CMOS Quad
2-Input OR Gate
With 5 V−Tolerant Inputs
The MC74LCX32 is a high performance, quad 2−input OR gate
operating from a 2.3 to 3.6 V 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 5.5 V allows MC74LCX32 inputs to be safely driven
from 5.0 V devices.
Current drive capability is 24 mA at the outputs.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
