V62/04715-02YE

Overview

The V62/04715-02YE is an Enhanced Product SN74LVTH16543-EP, a 3.3-V ABT 16-bit registered transceiver with 3-state outputs manufactured by Texas Instruments. It utilizes Advanced BiCMOS technology for low static-power dissipation and supports mixed-mode signal operation, allowing 5-V input and output voltages with a 3.3-V VCC supply. The device operates on unregulated battery voltage down to 2.7 V and features Ioff and power-up 3-state support for hot insertion applications. It includes bus hold circuitry on data inputs to eliminate external pullup/pulldown resistors.

Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant inputs and outputs while operating at 3.3 V
• Provides active bus-hold circuitry on data inputs to maintain valid logic levels without external components
• Features Ioff and power-up 3-state circuitry to prevent damaging current backflow and driver conflicts during hot insertion

Applications

• Mixed-mode signal environments requiring 5-V interface compatibility with 3.3-V systems
• Hot-insertion applications utilizing Ioff and power-up 3-state protection
• Unregulated battery-powered systems operating down to 2.7 V

Procurement Notes

Verify the specific package type and temperature range associated with the suffix. This part number corresponds to the SSOP (DL) package with an operating temperature range of -55°C to 125°C. Confirm that the enhanced product qualification pedigree meets the reliability requirements for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a 16-bit registered transceiver is required for 3.3-V ABT logic families. It is suitable for designs needing independent control of two 8-bit sections via separate latch-enable and output-enable inputs. Ensure the design accommodates the flow-through architecture to optimize PCB layout and minimize high-speed switching noise through distributed VCC and GND pins.

Part Context

This component belongs to the Texas Instruments Widebus family and is based on the SN74LVTH16543-EP specification. It is classified as an Enhanced Product, indicating controlled baseline manufacturing with one assembly/test site and one fabrication site. The device is designed for extended temperature ranges and includes enhanced diminishing manufacturing sources support.

Replacement Considerations

V62/04715-01XE is a qualified alternative version of the SN74LVTH16543-EP. Note that V62/04715-01XE utilizes the TSSOP (DGG) package and has an industrial temperature range (-40°C to 85°C), whereas V62/04715-02YE uses the SSOP (DL) package and military temperature range (-55°C to 125°C). Verify package compatibility and thermal requirements.
