SN74LV245ATNS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATNS is an octal bus transceiver from the Texas Instruments SN74LV245A series, designed for asynchronous bidirectional data communication between buses. It operates within a supply voltage range of 2V to 5.5V and features non-inverting logic with three-state outputs. The device utilizes TTL/CMOS input levels and LVTTL output levels, supporting mixed-mode operation across all ports. Key electrical characteristics include a maximum propagation delay of 6.5ns at 5V, low power consumption with a maximum supply current of 1µA, and robust electrostatic discharge protection exceeding JESD22 standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TNS' against the official datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage requirements ranging from 2V to 5.5V. Confirm that the selected variant meets the necessary ESD protection levels for the intended environment. Cross-reference ordering information with manufacturer documentation to avoid substitution errors.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage flexibility between 2V and 5.5V. The LV series offers faster switching speeds compared to standard LS logic while maintaining CMOS low power characteristics. Consider the Ioff feature if the design requires isolation during power-down states to protect downstream components from unintended current flow.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV245A family of octal bus transceivers manufactured by Texas Instruments. The LV (Low-Voltage CMOS) series is engineered for high-speed operations with reduced power dissipation. The device serves as a critical interface component in digital circuits, facilitating reliable data transfer across buses with varying voltage domains.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include SN74LVC245 variants for lower voltage applications or SN74ALS245 for higher speed requirements.
