Product details
Overview
V62/06609-01XE from Texas Instruments is a radiation-hardened, high-reliability 16-bit noninverting bus transceiver with 3-state outputs, designed for synchronous bidirectional data transfer between A and B buses in harsh-environment systems. It operates across –55°C to 125°C, supports 4.5 V–5.5 V supply, delivers ±32 mA high-drive outputs, and features dual direction-control (1DIR/2DIR) and output-enable (1OE/2OE) inputs for flexible 8-bit or 16-bit configuration in space-grade avionics and defense electronics.
For engineers reviewing the V62/06609-01XE datasheet, V62/06609-01XE pinout, V62/06609-01XE application, or V62/06609-01XE equivalent, key selection considerations include its SSOP-48 (DL) package, extended temperature qualification, EPIC-IIB™ BiCMOS process, high-noise-immunity input thresholds (VIL = 0.8 V, VIH = 2 V), and guaranteed isolation during power-up/down below 2.1 V.
Technical Context
The V62/06609-01XE implements two independent 8-bit transceiver sections-each with dedicated DIR and OE controls-enabling simultaneous or segregated A↔B data flow. Its flow-through pin architecture minimizes PCB trace crossovers and reduces signal skew across all 16 channels.
It uses distributed VCC/GND pinning (12 power/ground terminals) to suppress high-speed switching noise, and incorporates EPIC-IIB™ BiCMOS logic for low propagation delay (tPLH/tPHL ≤ 4 ns at 5 V, CL = 50 pF) while maintaining latch-up immunity >500 mA per JESD70 and ESD protection >2000 V HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5-V TTL/CMOS systems and stable operation under rail droop. |
| Operating Temperature | –55°C to 125°C - Qualified per MIL-PRF-38535 Class V for use in satellite payloads and airborne mission computers. |
| Output Drive | –32 mA IOH / +64 mA IOL - Supports heavy capacitive loads and long trace routing without external buffers. |
| Propagation Delay | ≤ 4 ns (tPLH/tPHL, VCC = 5 V, CL = 50 pF) - Enables reliable timing closure in 100+ MHz bus interfaces. |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - Guarantees robust noise margin (>0.7 V) against ground bounce and crosstalk in dense layouts. |
| Power-Up State | High-impedance when VCC < 2.1 V - Prevents bus contention during power sequencing in multi-rail systems. |
| Package | SSOP-48 (DL) - 0.5-mm pitch, 12.0 × 6.2 mm body - Compatible with automated SMT assembly and meets MIL-STD-883 thermal cycling requirements. |
Pinout & Package
Package: Shrink Small-Outline Package (SSOP), DL variant, 48-pin, 0.5-mm lead pitch, JEDEC MO-153 compliant. Body dimensions: 12.0 mm × 6.2 mm × 2.4 mm (max height). Moisture Sensitivity Level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active-high) | Selects data flow direction per 8-bit section: DIR = L → B-to-A; DIR = H → A-to-B. |
| 1OE, 2OE | Output enable input (active-low) | Disables all outputs in corresponding section to high-impedance state; enables tristate isolation. |
| 1A1–1A8, 2A1–2A8 | A-side data I/O ports | Connect to source bus; driven by internal logic when OE = L and DIR configures direction. |
| 1B1–1B8, 2B1–2B8 | B-side data I/O ports | Connect to destination bus; outputs reflect A-side data (or vice versa) based on DIR state. |
| VCC (pins 7, 18, 24, 34, 40, 45) | Power supply | Six distributed VCC pins reduce IR drop and improve PSRR across high-frequency switching. |
| GND (pins 4, 10, 15, 21, 28, 31, 39, 42) | Ground reference | Eight GND pins provide low-inductance return paths and minimize ground bounce (VOLP < 1 V). |
Key Features
| Feature | Design Value |
|---|---|
| EPIC-IIB™ BiCMOS Process | Reduces dynamic power vs. standard bipolar while retaining TTL-compatible drive strength and speed. |
| Distributed Power/Ground Pins | 14 total VCC/GND terminals suppress simultaneous switching noise and improve signal integrity at >100 MHz. |
| Flow-Through Pinout | Input and output pins arranged linearly (A→B or B→A) to eliminate layer jumps and minimize trace length mismatch. |
| Power-Up/Down High-Z | Guaranteed high-impedance state when VCC is between 0–2.1 V - eliminates bus contention during sequencing. |
| Latch-Up Immunity | >500 mA per JESD70 - ensures survivability in single-event transient (SET) environments common in space applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN54ABT16245A | Military QML-38535 Class B qualified; same electrical specs but rated only to –55°C to 125°C without enhanced DMS pedigree or radiation tolerance testing. | Lacks V62/06609-01XE's radiation hardness assurance and extended reliability screening (e.g., biased 85/85, HAST). | Preferred for non-radiation environments where full V62 qualification is not required and cost sensitivity is higher. |
| SN74ABT16245A | Commercial catalog version; identical pinout and logic function but rated only for –40°C to 85°C and unqualified for space or defense use. | Not suitable for extended temperature or high-reliability deployments; lacks controlled baseline and DMS support. | Appropriate for lab prototyping or terrestrial industrial systems where environmental stress is moderate. |
Compared with SN54ABT16245A and SN74ABT16245A, V62/06609-01XE adds radiation tolerance validation, enhanced manufacturing pedigree, and guaranteed performance across the full –55°C to 125°C range with documented reliability life modeling at elevated junction temperatures.

FAQ
What is the operating temperature range of the V62/06609-01XE?
The V62/06609-01XE is fully characterized and qualified for continuous operation from –55°C to 125°C, meeting MIL-PRF-38535 Class V requirements. This range is validated through temperature cycling, biased 85/85, and HAST testing - ensuring reliability in satellite thermal vacuum environments and airborne engine bay installations where the V62/06609-01XE serves as a core bus interface element.
Does the V62/06609-01XE support hot-swap or live insertion?
Yes - the V62/06609-01XE enters a guaranteed high-impedance state when VCC is below 2.1 V, preventing bus contention during partial power application. When used with proper current-limiting and slew-rate-controlled power sequencing, the V62/06609-01XE enables safe live insertion into powered backplanes, a key requirement in modular avionics systems where the V62/06609-01XE bridges field-replaceable units.
What package type and footprint does the V62/06609-01XE use?
The V62/06609-01XE uses a 48-pin Shrink Small-Outline Package (SSOP-DL) with 0.5-mm lead pitch, 12.0 mm × 6.2 mm body size, and JEDEC MO-153 compliance. Its pinout follows TI's Widebus™ flow-through architecture, and the package carries MSL Level-1 rating for unlimited floor life - making the V62/06609-01XE compatible with standard SMT reflow profiles and automated optical inspection in high-mix defense manufacturing lines.
How does the V62/06609-01XE handle power-up and power-down sequencing?
The V62/06609-01XE automatically enters a high-impedance state when VCC is between 0 V and 2.1 V, eliminating bus conflicts during asymmetric power ramping. For robust isolation above 2.1 V, OE must be pulled high via external resistor; the V62/06609-01XE datasheet specifies minimum pull-up values based on driver sink capability - a critical detail for fail-safe operation in triple-redundant flight computers relying on the V62/06609-01XE for cross-channel data exchange.
Is the V62/06609-01XE pin-compatible with commercial SN74ABT16245A variants?
Yes - the V62/06609-01XE shares identical pinout, logic function, and DC/AC electrical specifications with SN74ABT16245A and SN54ABT16245A. However, it adds radiation tolerance validation, enhanced reliability screening, and extended temperature qualification - meaning the V62/06609-01XE can directly replace those parts in high-reliability designs without layout changes, provided system-level radiation and thermal requirements are met.
