Low-Voltage CMOS Octal Buffer Flow Through Pinout

With 5V–Tolerant Inputs and Outputs (3–State, Inverting)

The MC74LCX540 is a high performance, inverting octal buffer operating from a 2.3 to 3.6V supply. This device is similar in function to the MC74LCX240, while providing flow through architecture.

• Designed for 2.3 to 3.6V VCC Operation

• 5V Tolerant — Interface Capability With 5V TTL Logic

• Supports Live Insertion and Withdrawal

• IOFF Specification Guarantees High Impedance When VCC = 0V

• LVTTL Compatible

• LVCMOS Compatible

• 24mA Balanced Output Sink and Source Capability

• Near Zero Static Supply Current in All Three Logic States (10µA)

Substantially Reduces System Power Requirements

• Latchup Performance Exceeds 500mA

• ESD Performance: Human Body Model >2000V; Machine Model >200V
