SN74LV540APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV540APW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LV logic series. It features eight inputs and outputs with three-state capability, housed in a 20-TSSOP surface-mount package. The device operates within a supply voltage range of 2.0 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. Key electrical specifications include a low-level output current of 16 mA and a high-level output current of -16 mA. Propagation delay varies based on voltage, measuring 15.2 ns at 2.5 V, 10.6 ns at 3.3 V, and 7.5 ns at 5 V.
