SN74LVTH245ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH245ADBR is a Texas Instruments octal bus transceiver featuring 3-state outputs, designed for 3.3-V ABT applications. It operates within a supply voltage range of 2.7 V to 3.6 V and supports LVTTL input and output levels. The device provides a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 2.3 ns at 3.3 V and functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional data transfer capability with non-inverting logic
• Supports mixed-mode operation allowing different voltage standards on A and B buses
• Includes Ioff feature to prevent back-driving when the device is powered down

Buffers, Drivers, Receivers, Transceivers Applications

• High-density data bus routing in embedded systems
• Clock drivers and buffer circuits
• Memory module interface connections

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'BR' indicates the SSOP-20 package variant rather than the SOIC version. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 3.3-V ABT technology with mixed-voltage compatibility. Ensure the SSOP-20 package fits the PCB layout constraints. Verify that the 64 mA sink current meets the load requirements for the connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH245A family of advanced bus transceivers. It shares functional similarities with the SN74LVT245 series but utilizes ABT technology optimized for 3.3-V operations. The device serves as a standard interface solution for connecting microprocessors to peripheral devices.
