MC74LCX540
Low-Voltage CMOS
Octal Buffer
Flow Through Pinout
With 5 V−Tolerant Inputs and Outputs
(3−State, Inverting)
http://onsemi.com
MARKING
The MC74LCX540 is a high performance, inverting octal buffer
operating from a 2.3 to 3.6 V supply. This device is similar in function
to the MC74LCX240, while providing flow through architecture.
High impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved

MC74LCX540 inputs to be safely driven from 5 V devices. The
MC74LCX540 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
(OE1, OE2) inputs, when HIGH, disables the outputs by placing them
in a HIGH Z condition.

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.
