74LX1G07CTR

Buffers, Drivers, Receivers, Transceivers Overview

The 74LX1G07CTR is a low-voltage CMOS single buffer with open drain output, fabricated using sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a supply voltage range of 1.65 V to 5.5 V, featuring 5 V tolerant inputs that accept 0 to 7 V regardless of the supply voltage. The device provides high-speed performance with a maximum propagation delay of 4.2 ns at VCC = 3.3 V and low power dissipation with a maximum quiescent supply current of 1 μA at 25°C. Power-down protection is included on both inputs and outputs.
