The MC74LVQ125 is a high performance, non–inverting quad buffer
operating from a 2.7 to 3.6V supply. The MC74LVQ125 is suitable for
memory address driving and all TTL level bus oriented transceiver
applications.
Current drive capability is 12mA at the outputs. The Output Enable
(OE) input, when HIGH, disables the output 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.
