Product details
Overview
V62/04715-02YE from Texas Instruments is a radiation-hardened, high-reliability 16-bit registered transceiver operating at 3.3 V VCC with dual 8-bit bidirectional data flow, 3-state outputs, bus-hold inputs, and Ioff support for hot insertion-designed for aerospace avionics and spaceborne digital backplane interfaces.
For engineers reviewing the V62/04715-02YE datasheet, V62/04715-02YE pinout, V62/04715-02YE application, or V62/04715-02YE equivalent, key selection criteria include its –55°C to 125°C extended temperature range, SSOP (DL) 56-pin package, ABT BiCMOS process, mixed-mode 5-V-tolerant I/O, and controlled baseline qualification pedigree per MIL-PRF-38535 Class V.
Technical Context
The V62/04715-02YE implements two independent 8-bit registered transceiver sections (A↔B), each with dedicated latch-enable (LEAB/LEBA), output-enable (OEAB/OEBA), and chip-enable (CEAB/CEBA) controls-enabling asynchronous, directionally isolated data latching and 3-state output gating. Its ABT architecture delivers TTL-compatible drive strength while maintaining 3.3-V core logic levels.
Bus-hold circuitry actively maintains valid logic states on floating A/B port inputs without external resistors, and Ioff protection disables outputs during power-down to prevent backdrive current. Power-up 3-state ensures high-impedance outputs during VCC ramp from 0–1.5 V, eliminating bus contention at power-on/off transitions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit registered transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVTH16543MDLREP | Same die, commercial-grade SSOP packaging; rated –40°C to 85°C, non-MIL-qualified | Lacks radiation-hardening, controlled baseline, and extended temperature validation | Select only for non-critical terrestrial industrial use where cost outweighs reliability requirements |
| V62/04715-01XE | Same functional die in TSSOP (DGG) package; identical electrical specs but different mechanical footprint and thermal resistance (θJA = 81°C/W vs. 73.5°C/W) | Lower pin density layout; less suitable for high-vibration aerospace mounting due to TSSOP lead geometry | Choose when PCB real estate permits larger pad pitch or when thermal dissipation margin exceeds 73.5°C/W requirement |
Compared with V62/04715-02YE, SN74LVTH16543MDLREP lacks military-grade qualification and extended temperature capability, while V62/04715-01XE trades mechanical robustness and thermal performance for smaller PCB area-making V62/04715-02YE the sole option meeting full space-grade environmental and reliability mandates.

FAQ
What is the maximum operating temperature range supported by V62/04715-02YE?
V62/04715-02YE is fully specified from –55°C to 125°C and qualified per MIL-PRF-38535 Class V for extended temperature operation in space and high-reliability military environments. This range is validated through temperature cycling, unbiased HAST, and autoclave testing-not derived from derating curves or commercial-grade data.
Does V62/04715-02YE support hot-swap insertion in live backplane systems?
Yes, V62/04715-02YE incorporates both Ioff and power-up 3-state circuitry explicitly designed for hot insertion. When VCC = 0 V, outputs are disabled to prevent backdrive current; during power-up (VCC 0–1.5 V), outputs remain in high-impedance state regardless of OE pin state-ensuring safe insertion into energized systems.
Can V62/04715-02YE interface directly with 5-V logic without external level shifters?
Yes, V62/04715-02YE supports mixed-mode signal operation: all inputs tolerate up to 5.5 V, and outputs drive 5-V TTL loads with VOH ≥ 2.4 V at IOL = 24 mA and VCC = 2.7 V. This eliminates external level translation in hybrid 3.3-V/5-V system architectures.
What package type and pin count does V62/04715-02YE use?
V62/04715-02YE uses the SSOP (DL) package with 56 pins, 0.5-mm pitch, and JEDEC MO-153-compliant dimensions (13.9 mm × 6.1 mm × 1.2 mm max). The pin-1 quadrant is Q1, and the package features eight VCC and eight GND terminals for low-noise power distribution.
Is bus-hold functionality enabled by default on V62/04715-02YE data inputs?
Yes, active bus-hold circuitry is integrated on all A and B port inputs of V62/04715-02YE and requires no external components or configuration. It maintains valid logic levels (VIH ≥ 2 V or VIL ≤ 0.8 V) on floating inputs with ±75 µA holding current-eliminating need for pullup/pulldown resistors in sparse or configurable I/O designs.
