SN74LV245ATNSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATNSR is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous bidirectional data communication between two buses. It operates within a supply voltage range of 2 V to 5.5 V and features three-state outputs. The device includes direction control (DIR) and output enable (OE) inputs to manage data flow and isolate the bus. It supports mixed-mode operation on all ports, allowing simultaneous use of different input and output logic levels. The component is housed in a 20-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides asynchronous bidirectional data transfer between two independent buses via dedicated direction control logic.
• Supports mixed-mode voltage operation across all ports, enabling interface between different logic families.
• Features three-state outputs that allow effective bus isolation when the output enable input is deactivated.
• Includes Ioff support to prevent reverse current flow during partial power-down conditions.
