SN74LV245ADB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ADB is an octal bus transceiver manufactured by Texas Instruments, belonging to the LV logic series. It features eight bidirectional data channels with three-state outputs and operates within a supply voltage range of 2 V to 5.5 V. The device utilizes CMOS technology and is housed in a 20-pin SSOP package. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 5 V and output drive capabilities of 16 mA for both high and low states. It supports mixed-mode operation across all ports and includes partial power-down protection via the Ioff feature.
