MC74LCX240
Low−Voltage CMOS
Octal Buffer
With 5 V−Tolerant Inputs and Outputs
(3−State, Inverting)
The MC74LCX240 is a high performance, inverting octal 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 MC74LCX240 inputs to be safely driven
from 5 V devices. The MC74LCX240 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
(OE) input, when HIGH, disables the outputs by placing them in a
HIGH Z condition.
Features
• Designed for 2.3 to 3.6 V VCC Operation
• 5 V Tolerant − Interface Capability With 5 V TTL Logic
• Supports Live Insertion and Withdrawal
• IOFF Specification Guarantees High Impedance When VCC = 0 V
• LVTTL Compatible
• LVCMOS Compatible

• 24 mA Balanced Output Sink and Source Capability
• Near Zero Static Supply Current in All Three Logic States (10 mA)
Substantially Reduces System Power Requirements
• Latchup Performance Exceeds 500 mA
• ESD Performance: Human Body Model >2000 V
Machine Model >200 V
• Pb−Free Packages are Available*
