SN74LVT245BNS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT245BNS is an octal bus transceiver from the Texas Instruments LVT series, housed in a 20-pin SOIC package. It operates at a minimum supply voltage of 2.7 V and a maximum of 3.6 V, with a propagation delay of 2.3 ns. The device features non-inverting logic with three-state outputs, supporting LVTTL input and output levels. It provides a low-level output current of 64 mA and a high-level output current of -32 mA. Operating temperatures range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission between two buses using eight independent channels.
• Designed for low-voltage 3.3-V operation while maintaining compatibility with 5-V systems via TTL interface capabilities.
• Features three-state outputs to isolate the device when not selected.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS requirements as indicated in the datasheet. Cross-reference the ordering information with the latest revision of the SN74LVT245B datasheet to avoid discrepancies in pinout or electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring an octal bus transceiver with 3.3-V ABT technology. It is suitable for designs needing a TTL interface to a 5-V system. Consider the 20-SOIC package constraints and the 2.3 ns propagation delay for timing-critical paths. Verify that the 64 mA low-level output current meets the load requirements of the destination bus.

Buffers, Drivers, Receivers, Transceivers Part Context
