Texas Instruments V62/04723-02YE

Overview

V62/04723-02YE from Texas Instruments is a radiation-hardened, high-reliability octal bus transceiver operating at 3.3 V VCC with 3-state outputs, supporting bidirectional data flow between A and B buses via DIR control and isolation via OE, rated for –55°C to 125°C operation in SSOP-20 package, and used in space-grade avionics data routing.

For engineers reviewing the V62/04723-02YE datasheet, V62/04723-02YE pinout, V62/04723-02YE application, or V62/04723-02YE equivalent, key selection criteria include its 3.3-V ABT logic family compatibility with 5-V TTL inputs, bus-hold circuitry eliminating external resistors, Ioff-enabled hot insertion, and guaranteed operation down to 2.7 V supply voltage.

Technical Context

This device implements asynchronous bidirectional bus translation using dual 8-bit data paths (A1–A8 ↔ B1–B8), controlled by a single-direction signal (DIR) and output-enable (OE) with active-low logic. Its ABT (Advanced BiCMOS Technology) architecture delivers low propagation delay (tPLH/tPHL ≤ 6 ns at VCC = 2.7 V) and high noise immunity.

It integrates bus-hold circuitry on all A/B port inputs (II(hold) ±750 µA max), Ioff protection (±100 µA at VCC = 0), and power-up 3-state behavior to prevent bus contention during power sequencing. The design supports mixed-mode signaling: 5-V-tolerant inputs with 3.3-V VCC and 3.3-V CMOS-compatible outputs.

FAQ

What is the maximum operating temperature range certified for V62/04723-02YE?

V62/04723-02YE is fully qualified for continuous operation from –55°C to 125°C per MIL-PRF-38535 Class V requirements, including thermal cycling, HAST, and unbiased autoclave testing. This range is verified across all electrical parameters in the official TI SCBS768A datasheet and V62 product addendum, and applies specifically to the SSOP-20 (DB) package variant marked LH245AMEP.

Does V62/04723-02YE support hot-plug insertion in powered-backplane systems?

Yes, V62/04723-02YE supports hot insertion via two integrated features: Ioff circuitry disables outputs when VCC = 0, blocking reverse current flow, and power-up 3-state forces outputs into high-impedance during power ramp-up. These functions are characterized and guaranteed in the SCBS768A datasheet under "Enhanced Product-Change Notification" and "Qualification Pedigree" sections, and apply directly to V62/04723-02YE.

Can V62/04723-02YE interface directly with 5-V logic inputs while operating at 3.3 V VCC?

Yes, V62/04723-02YE accepts input voltages up to 5.5 V on all A and B port pins while powered from 3.3 V, enabling direct connection to 5-V TTL outputs without external level shifters. This mixed-mode capability is explicitly stated in the "Features" and "Recommended Operating Conditions" tables of the SCBS768A datasheet and confirmed for the V62/04723-02YE variant in TI's V62 packaging addendum.

Is bus-hold functionality enabled by default on all data pins of V62/04723-02YE?

Yes, active bus-hold circuitry is integrated on all 16 data terminals (A1–A8 and B1–B8) of V62/04723-02YE and requires no external components or configuration. It maintains floating inputs at valid logic levels with ±750 µA dynamic hold current, as specified in the "Electrical Characteristics" table of SCBS768A and validated for the V62/04723-02YE production lot.

What package type and lead finish does V62/04723-02YE use?

V62/04723-02YE uses the SSOP-20 (DB) package with 0.65 mm lead pitch, 7.5 mm × 5.6 mm body, and NIPDAU (nickel-palladium-gold) lead finish. This is confirmed in TI's PACKAGE OPTION ADDENDUM dated 11-Nov-2025, where V62/04723-02YE is listed with DB package, MSL Level-1, and part marking LH245AMEP - matching the DB0020A mechanical drawing.
