SN74ALVTHR16245VR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTHR16245VR is a dual 8-bit bus transceiver from the ALVTHR logic series by Texas Instruments. It features non-inverting polarity and operates with a supply voltage range of 1.65 V to 3.6 V. The device provides three-state outputs and utilizes an SSOP-48 package. Key electrical parameters include a maximum propagation delay of 3.1 ns at 30 pF load, with output currents specified at -12 mA for high level and 12 mA for low level. It supports an operating temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable as two independent 8-bit or one unified 16-bit bidirectional data bus transceiver
• Supports mixed-voltage operation between 1.65-V and 3.6-V buses for safe interface
• Provides three-state outputs to isolate the device when not active

• Bus-oriented communications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'VR' corresponds to the TVSOP-48 tape-and-reel packaging configuration. Confirm that the required voltage levels match the 1.65-V to 3.6-V operational range. Ensure the design accommodates the specified propagation delay and output drive capabilities for the target application timing requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring flexible bus width configuration between 8-bit and 16-bit modes. It is suitable for applications needing voltage translation between different power domains within the specified range. Consider the thermal performance and package size constraints associated with the SSOP-48 form factor during PCB layout.
