SN74LVTH652IPWREP

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652IPWREP 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 integrates bus-transceiver circuits, D-type flip-flops, and control circuitry for multiplexed data transmission from the bus or internal registers. The device supports mixed-mode signal operation, unregulated battery operation down to 2.7 V, and hot-insertion via Ioff and power-up 3-state features. It operates within a supply voltage range of 2.7 V to 3.6 V and an ambient temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports multiplexed transmission of data directly from the data bus or from internal storage registers using select-control inputs.
• Active bus-hold circuitry maintains unused or floating data inputs at valid logic levels without external pullup/pulldown resistors.
• Eliminates decoding glitches during transitions between real-time and stored data transfer modes.
• Provides Ioff and power-up 3-state support to prevent damaging current backflow and driver conflicts during hot insertion.

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed data transmission in 3.3-V system environments
• Mixed-signal applications requiring 5-V input/output compatibility with 3.3-V VCC
• Hot-insertion bus management systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as active for new designs. Confirm the package type is TSSOP-24 (PW) and the ordering suffix matches IPWREP. Ensure procurement channels provide the standard tape and reel packaging quantity of 2000 units. Cross-reference the manufacturer part number SN74LVTH652IPWREP against official Texas Instruments documentation to validate authenticity and revision history before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require simultaneous real-time and registered data paths on an octal bus. It is suitable for applications needing TTL-level input compatibility while operating at 3.3 V. Consider its latch-up performance exceeding 500 mA per JESD 17 and ESD protection ratings when evaluating robustness requirements for industrial or commercial environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVTH series of low-voltage CMOS logic components manufactured by Texas Instruments. It is specifically engineered for 3.3-V applications but maintains compatibility with 5-V system interfaces. The 'EP' designation indicates enhanced plastic construction, often associated with controlled baseline manufacturing and enhanced diminishing manufacturing sources support.
