SN74LVT245BDB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT245BDB is an octal bus transceiver from the Texas Instruments LVT series, designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It features a 20-pin SSOP package and provides non-inverting data transmission. The device supports bidirectional data flow controlled by a direction pin and includes three-state outputs for effective bus management.

• Clock drivers
• Bus-oriented architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DB' confirms the 20-SSOP package variant. Confirm RoHS compliance status as indicated in distributor records. Ensure the order matches the exact part number to avoid confusion with similar LVC or LVT variants that may have different pin counts or electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 3.3-V ABT logic with 5-V TTL systems. It is suitable for designs requiring bidirectional data flow on an octal bus. Consider the 20-SSOP package constraints for PCB layout. Verify that the 3.3-V supply voltage aligns with the target system requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVT245 family of octal bus transceivers. It is distinct from the SN74LVC8T245 series, which operates over a wider voltage range (1.65 V to 5.5 V). The LVT series is specifically optimized for 3.3-V operations while maintaining compatibility with 5-V inputs.
