SN74LVC540ANSR TI Buffer/Driver | 20-SO | 3.3V, 8-Channel, Inverting

Product Overview

The SN74LVC540ANSR is a high-performance, 8-bit buffer and line driver from Texas Instruments, designed for 2.7-V to 3.6-V VCC operation. It features inverting outputs and is part of the LVC family, offering low-voltage operation with high drive capability. The device is ideal for driving bus lines or buffering memory address registers. Its flow-through pinout simplifies PCB layout, and it supports partial-power-down mode via Ioff circuitry, which prevents damaging backflow current when the device is powered down.
