SN74LV245ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ANS 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 2V to 5.5V and features three-state outputs. The device utilizes LV/LV-A/LVX/H logic series technology and is housed in a 20-pin SOIC package. Key electrical characteristics include a maximum propagation delay of 6.5ns at 5V and support for mixed-mode voltage operation across all ports.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and temperature rating against the datasheet before procurement. Confirm that the SN suffix corresponds to the standard operating temperature range required for your application. Ensure compatibility with the target voltage levels on both bus sides to maintain signal integrity during mixed-mode operations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage flexibility between 2V and 5.5V. It is suitable for applications needing low noise performance and high ESD protection. Consider the 6.5ns propagation delay limit at 5V for timing constraints. Verify that the 20-pin SOIC package fits the PCB layout requirements.
