V62/04715-01XE

Overview

V62/04715-01XE is a military-enhanced SN74LVTH16543-EP, a 3.3-V ABT 16-bit registered transceiver with 3-state outputs. It supports mixed-mode signal operation (5-V input and output voltages with 3.3-V VCC) and unregulated battery operation down to 2.7 V. The device features Ioff and power-up 3-state support for hot insertion, bus hold on data inputs, and distributed VCC and GND pins to minimize high-speed switching noise. It operates from -40 °C to 85 °C in a TSSOP-DGG package.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages with 3.3-V VCC
• Provides Ioff and power-up 3-state functionality for safe hot insertion applications
• Includes active bus-hold circuitry on data inputs to eliminate the need for external pullup/pulldown resistors
• Features distributed VCC and GND pins to minimize high-speed switching noise

Applications

• Mixed-mode signal interfaces between 5-V and 3.3-V system environments
• Hot-insertion applications requiring controlled power-up states
• Unregulated battery-powered systems operating down to 2.7 V

Procurement Notes

Verify that the procurement matches the exact part number V62/04715-01XE, which corresponds to the SN74LVTH16543-EP enhanced product variant. Confirm the package type is TSSOP-DGG and the operating temperature range is -40 °C to 85 °C. Ensure the supplier provides documentation confirming the component meets the specified qualification pedigree and military enhancement standards as defined by Texas Instruments.

Selection Notes

Select this component when designing systems that require bidirectional data transfer between 5-V and 3.3-V logic domains. It is suitable for applications needing hot-swap capabilities without external control circuitry due to its integrated Ioff and power-up 3-state features. Consider the TSSOP-DGG package if space constraints allow for a 56-pin surface-mount footprint.
