V62/04723-02YE

Overview

V62/04723-02YE is a military-grade SN74LVTH245A-EP octal bus transceiver manufactured by Texas Instruments. It operates at 3.3 V with TTL-compatible inputs and supports mixed-mode signal operation for 5-V systems. The device features 3-state outputs, active bus-hold circuitry, and Ioff/power-up 3-state protection for hot insertion. It is housed in a DB (SSOP) package and qualified to an extended temperature range of -55 °C to +125 °C.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages with 3.3-V VCC
• Provides active bus-hold circuitry on data inputs to eliminate the need for external pullup/pulldown resistors
• Includes Ioff and power-up 3-state circuitry to support hot-insertion applications without damaging current backflow
• Features enhanced ESD protection exceeding JESD 22 standards and latch-up performance exceeding 500 mA per JESD 17

Applications

• Asynchronous communication between data buses
• Mixed-mode signal operation environments requiring 5-V interface compatibility
• Hot-insertion applications utilizing Ioff and power-up 3-state capabilities

Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific revision level against the latest TI documentation. Ensure the component meets the necessary environmental qualifications for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when an octal bus transceiver with 3.3-V operation and 5-V tolerance is required. It is suitable for designs needing active bus-hold functionality and robust hot-insertion protection. Verify that the SSOP package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the SN74LVTH245A-EP family, representing an enhanced product variant designed for demanding environments. It provides controlled baseline manufacturing and enhanced diminishing manufacturing sources support. The device ensures reliable operation over an extended temperature range through rigorous qualification testing.

Replacement Considerations

The catalog version SN74LVTH245A serves as a commercial alternative. For military-specific requirements, verify if other QML certified variants are available. Ensure any substitute maintains the same package outline and electrical characteristics.
