MC74LCX125
Low−Voltage CMOS
Quad Buffer
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX125 is a high performance, non−inverting quad
buffer 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 VI specification of 5.5 V allows MC74LCX125 inputs
to be safely driven from 5.0 V devices. The MC74LCX125 is suitable
for memory address driving and all TTL level bus oriented transceiver
applications.
Current drive capability is 24 mA at the outputs. The Output Enable
(OEn) inputs, when HIGH, disable the outputs by placing them in a
HIGH Z condition.
Features
Designed for 2.3 to 3.6 V VCC Operation
5.0 V Tolerant − Interface Capability With 5.0 V TTL Logic
Supports Live Insertion and Withdrawal
IOFF Specification Guarantees High Impedance When VCC = 0 V
LVTTL Compatible

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.
1. IO absolute maximum rating must be observed.
