SN74LVTH652DBRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652DBRE4 is an octal bus transceiver and register manufactured by Texas Instruments. It operates at a supply voltage of 2.7 V to 3.6 V with TTL-compatible inputs supporting 5-V signals. The device features independent output enables, select controls for real-time or stored data transfer, and active bus-hold circuitry. It includes Ioff and power-up 3-state support for hot insertion. The package is a 24-pin SSOP (DB) in tape and reel format.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V input tolerance while operating at 3.3 V
• Provides registered bus management with D-type flip-flops for storing A and B bus data
• Includes active bus-hold circuitry to maintain valid logic levels on floating inputs
• Enables safe hot insertion via Ioff and power-up 3-state output control

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission of data between buses
• Storage and retrieval of bus data using internal registers
• Hot-swappable system designs requiring controlled power-up states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the DB suffix indicates the SSOP-24 package and RE4 confirms lead-free status. Confirm the datasheet revision matches design requirements. Ensure ESD protection ratings meet system specifications. Check RoHS compliance documentation for regulatory adherence.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer with storage capability is required. It is suitable for systems needing TTL-to-CMOS level translation. Consider the 24-pin SSOP package for space-constrained PCB layouts. Verify that the 3.3 V supply voltage aligns with the target system architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH652 family of octal bus transceivers. It is designed for low-voltage applications but maintains compatibility with 5-V environments. The device integrates both transceiver and register functions into a single IC for efficient bus management.
