SN74LVTH652DGVRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652DGVRE4 is an octal bus transceiver and register designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It features independent output enable controls (OEAB, OEBA) and select-control inputs (SAB, SBA) for multiplexed transmission of real-time or stored data. The device includes D-type flip-flops for data storage and active bus-hold circuitry on data inputs. It supports hot insertion via Ioff and power-up 3-state functionality, ensuring outputs remain in a high-impedance state during power transitions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation by interfacing 5-V input/output voltages with 3.3-V VCC systems
• Provides active bus-hold circuitry on data inputs to maintain valid logic levels without external resistors
• Features Ioff and power-up 3-state support to prevent damaging current backflow and driver conflicts during hot insertion
• Includes dedicated control circuitry to eliminate decoding glitches during transitions between real-time and stored data modes

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission of data between buses using internal storage registers
• Hot-insertion applications requiring controlled high-impedance states during power cycling
• Mixed-voltage system environments bridging 5-V and 3.3-V logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm that the 'DGVR' package designation matches the required TVSOP physical dimensions and pinout for your PCB layout. Ensure compatibility with the -40°C to +85°C operating temperature range specified for this commercial grade variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data transfer requires simultaneous real-time pass-through and registered storage capabilities. The integrated select controls allow direct switching between bus data and flip-flop outputs without external decoding logic. Consider the TVSOP package for space-constrained designs requiring surface-mount assembly with standard reflow profiles.
