SN74LVTH652DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652DBR is an octal bus transceiver and register manufactured by Texas Instruments. It operates on a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input and output voltages with 3.3-V VCC. The device features active bus-hold circuitry to maintain valid logic levels on floating inputs without external resistors. It includes Ioff and power-up 3-state support for hot-insertion applications. The component is housed in a 24-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports multiplexed transmission of data directly from the data bus or internal storage registers via D-type flip-flops.
• Active bus-hold circuitry eliminates the need for external pullup or pulldown resistors on unused or floating data inputs.
• Provides Ioff and power-up 3-state functionality to prevent damaging current backflow and driver conflicts during hot insertion.

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal operation between 5-V systems and 3.3-V VCC environments
• Unregulated battery operation down to 2.7 V
• Hot-insertion applications requiring high-impedance state control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific orderable part number matches the required package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement. Ensure all unused control inputs are properly terminated at VCC or GND to guarantee correct device operation as specified in the datasheet.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require bidirectional data transfer combined with storage capabilities. It is suitable for systems needing TTL interface compatibility with low-voltage logic. Consider its latch-up performance exceeding 500 mA per JESD 17 and ESD protection ratings when evaluating robustness requirements.
