SN74LVTH652NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652NSR is an octal bus transceiver and register manufactured by Texas Instruments in a 24-pin NS (SOIC) package. It operates on a supply voltage range of 2.7 V to 3.6 V with TTL-compatible inputs. The device features independent output enable controls, select-control inputs for real-time or stored data transfer, and active bus-hold circuitry. Recommended operating conditions specify low-level output currents up to 64 mA and high-level output currents up to -32 mA at 3.0 V. Propagation delays are typically 3.1 ns at 3.3 V with a 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages during 3.3-V VCC operation
• Includes internal D-type flip-flops for storing data from the A or B data buses
• Features active bus-hold circuitry to maintain valid logic levels on floating data inputs
• Provides Ioff and power-up 3-state support to prevent damaging current backflow during hot insertion

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission of data between system buses
• Bus management applications requiring storage and transfer of data
• Hot-insertion environments utilizing power-up 3-state capabilities
• Mixed-voltage system interfaces bridging 3.3-V and 5-V logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOIC-24 tape and reel packaging configuration. Confirm that the component meets the required RoHS compliance standards and lead finish specifications for your assembly process. Ensure the operating temperature range aligns with your application's thermal requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data flow with optional storage capabilities. It is suitable for applications needing independent control over data direction and storage selection. Consider its tolerance for unregulated battery operation down to 2.7 V if power stability varies within the specified range.
