V62/04709-02YE

Overview

The V62/04709-02YE is a military-grade SN74LVTH162245-EP 16-bit dual-octal noninverting 3-state transceiver. It operates on a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation with 5-V input tolerance. The device features active bus-hold circuitry, Ioff support for hot insertion, and distributed power pins to minimize switching noise. It is housed in a 48-pin SSOP (DL) package.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V input compatibility with 3.3-V systems
• Includes active bus-hold circuitry to maintain valid logic states without external resistors
• Provides Ioff and power-up 3-state functionality to prevent current backflow during hot insertion
• Features A-port outputs with equivalent series resistors to reduce signal overshoot and undershoot

Applications

• Military and defense electronic systems requiring enhanced durability
• Hot-swappable data bus architectures
• Mixed-voltage system interconnects between 3.3-V and 5-V components
• High-density PCB layouts utilizing flow-through architecture

Procurement Notes

Verify the specific ordering suffix '-02YE' corresponds to the SSOP (DL) package variant when sourcing. Confirm that the component meets the required extended temperature range specifications for your application environment. Ensure compliance with all relevant military qualification standards before final integration into critical systems.

Selection Notes

Select this component for applications requiring robust 16-bit bidirectional data transmission across mixed-voltage domains. The device is suitable where hot-swap capabilities are necessary to protect connected buses from damage during power cycling. Consider the SSOP package constraints regarding thermal dissipation and physical space availability on the target printed circuit board layout.

Part Context
