The MC74LVQ541 is a high performance, non–inverting octal buffer
operating from a 2.7 to 3.6V supply . This device is similar in function to the
MC74LVQ244, while providing flow through architecture. The
MC74LVQ541 is suitable for memory address driving and all TTL level
bus oriented buffer applications.

Current drive capability is 12mA at the outputs. The Output Enable
(OE1

. OE2) inputs, when HIGH, disable the outputs by placing them in a

HIGH Z condition.

• Designed for 2.7 to 3.6V V

CC

Operation – Ideal for Low Power/Low

Noise Applications

• Guaranteed Simultaneous Switching Noise Level and Dynamic

Threshold Performance

• Guaranteed Skew Specifications

• Guaranteed Incident Wave Switching into 75Ω

• Low Static Supply Current (10µA) Substantially Reduces System Power

Requirements

• Latchup Performance Exceeds 500mA

• ESD Performance: Human Body Model >2000V

1. These values of VI are used to test DC electrical characteristics only. Functional test should use VIH ≥ 2.4V, VIL ≤ 0.5V.

2. Incident wave switching on transmission lines with impedances as low as 75Ω for commercial temperature range is guaranteed. Maximum test

duration is 2ms, one output loaded at a time.
