SN74LVT245BDWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT245BDWR is an octal bus transceiver from the Texas Instruments LVT logic series, housed in a 20-pin SOIC package. It operates within a supply voltage range of 2.7 V to 3.6 V and features non-inverting data transmission with three-state outputs. The device supports LVTTL input and output levels, providing a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 2.3 ns, with a maximum power supply current of 5 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two buses using direction control inputs
• Features three-state outputs to effectively isolate the bus when disabled
• Supports mixed-mode operation allowing ports to function at different voltage levels
• Includes Ioff support to prevent back-driving when the device is powered down

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous bidirectional communication between data buses
• Memory and memory-mapped interface implementations
• Clock drivers and buffered oscillators
• Bus-oriented communications systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm RoHS compliance and environmental status. Confirm the package type matches the required PCB footprint. Ensure the operating voltage range aligns with the target system design. Check for any recent product change notices that may affect material composition or performance specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 3.3 V logic compatibility with high drive capability. The LVT series offers faster switching speeds compared to standard LV devices. Consider the 20-SOIC package for surface mount assembly requirements. Evaluate the propagation delay and output current specifications against the load conditions of the connected circuitry.
