Product details
Overview
V62/04738-01XE from Texas Instruments is a radiation-hardened, high-drive octal bus transceiver with direction control (DIR) and output-enable (OE), designed for asynchronous bidirectional data transfer between A and B buses in harsh-environment systems. It delivers −24-mA IOH / 32-mA IOL drive strength, supports hot insertion via Ioff and power-up 3-state, and operates across −55°C to 125°C.
For engineers reviewing the V62/04738-01XE datasheet, V62/04738-01XE pinout, V62/04738-01XE application, or V62/04738-01XE equivalent, key selection criteria include extended temperature operation, latch-up immunity (>500 mA), ESD robustness (2000-V HBM), ground-bounce performance (<1 V VOLP), and SSOP-20 package compatibility with space-grade PCB layouts.
Technical Context
This device implements TTL-compatible 8-bit bidirectional bus interface logic with independent DIR and OE controls. Its dual-rail isolation architecture enables safe hot-insertion: Ioff limits reverse current when VCC = 0 V, while power-up 3-state ensures outputs remain high-impedance during supply ramp-up/down.
It features enhanced reliability qualifications per JEDEC JESD17 (latch-up), biased 85/85 and HAST (bias + humidity), temperature cycling, and intermetallic bond life testing - confirming suitability for military and aerospace platforms requiring long-term operational stability under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures stable operation with standard 5-V rail tolerances in avionics and defense power systems. |
| IOH / IOL | −24 mA / 32 mA - Drives heavy capacitive loads (e.g., backplane traces or multiple inputs) without signal degradation. |
| Propagation Delay | tPLH/tPHL ≤ 4.2 ns @ 5 V - Supports high-speed data handshaking up to ~200 MHz system clock domains. |
| Operating Temperature | −55°C to 125°C - Validated for deployment in satellite payload bays, engine-mounted controllers, and desert-deployed radar units. |
| ESD Protection | 2000-V HBM, 200-V MM - Withstands handling and field-level electrostatic discharge in uncontrolled environments. |
| Latch-Up Immunity | >500 mA per JESD17 - Prevents destructive latch-up during voltage transients or ground bounce events. |
| VOLP (Ground Bounce) | <1 V @ VCC = 5 V, TA = 25°C - Minimizes noise coupling into adjacent sensitive analog or RF circuitry on shared PCBs. |
Pinout & Package
Package: SSOP-20 (DB), 7.5 mm × 5.6 mm body, 0.65 mm lead pitch, 2.0 mm max height, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DIR | Direction Control Input | Low = B→A data flow; High = A→B data flow - Enables dynamic bus arbitration without external logic. |
| 2–9 A1–A8 | Port A Data Inputs/Outputs | Bidirectional I/O pins tied to local subsystem bus; high-impedance when OE = High or VCC = 0. |
| 10 GND | Ground Reference | Primary return path for all I/O and internal logic; must be low-inductance connection in high-speed layouts. |
| 11 VCC | Power Supply | 5-V nominal supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for noise suppression. |
| 12 OE | Output Enable Input | Low = transceiver active; High = both ports isolated - Used for bus contention prevention and power sequencing control. |
| 13–20 B1–B8 | Port B Data Inputs/Outputs | Bidirectional I/O pins connected to remote bus segment; electrically identical to A-side with matched timing. |
Key Features
| Feature | Design Value |
|---|---|
| Hot-Insertion Support | Ioff and power-up 3-state eliminate backfeed current and bus conflicts during live board replacement in modular avionics racks. |
| High-Drive Outputs | −24-mA source / 32-mA sink capability drives 50-pF loads with <4.2-ns propagation delay, enabling legacy TTL bus interfacing. |
| Extended Temp Qualification | JEDEC JESD17 latch-up, biased 85/85, HAST, and thermal cycle testing confirm reliability over full −55°C to 125°C range. |
| Low Ground Bounce | VOLP <1 V at 5 V ensures minimal noise injection into shared ground planes - critical for mixed-signal payloads. |
| Controlled Baseline | Single assembly/test site and single fabrication site guarantee consistent parametric distribution and traceable lot history. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT245BMDBREP | Same DB package, identical electrical specs, commercial-temp version (−40°C to 85°C); no radiation hardening or extended temp qualification. | Approved for industrial automation and test equipment - not rated for space or military deployment. | Select only if operating environment stays within commercial temperature range and radiation exposure is negligible. |
| V62/04737-01XE | Same family, but configured as octal buffer (non-inverting, unidirectional); lacks DIR pin and B→A capability. | Suitable for fixed-direction data paths (e.g., ADC output latching), not bidirectional bus arbitration. | Choose when system architecture requires one-way data flow and space savings justify eliminating DIR logic. |
Compared with SN74ABT245BMDBREP and V62/04737-01XE, V62/04738-01XE uniquely combines bidirectional control, extended temperature operation, and radiation-hardened process - making it the sole option for mission-critical aerospace bus bridging where direction flexibility and environmental resilience are non-negotiable.

FAQ
What is the maximum operating temperature range certified for V62/04738-01XE?
V62/04738-01XE is fully qualified for continuous operation from −55°C to 125°C, validated per JEDEC JESD17 and enhanced environmental stress testing including biased 85/85, HAST, and thermal cycling. This range is explicitly documented in the SCBS798 datasheet and TI's Package Option Addendum, confirming suitability for spacecraft thermal vacuum chambers and jet engine-mounted control units where ambient extremes exceed commercial limits.
Does V62/04738-01XE support hot insertion, and how is it implemented?
Yes, V62/04738-01XE supports hot insertion via two integrated features: Ioff circuitry disables outputs when VCC = 0 V to prevent damaging back-current, and power-up 3-state holds outputs in high-impedance during supply ramp-up/down. These functions are verified in the SCBS798 datasheet under "Ioff and Power-Up 3-State Support Hot Insertion" and confirmed by TI's enhanced product-change notification pedigree.
What package type and footprint does V62/04738-01XE use, and are layout guidelines available?
V62/04738-01XE uses the SSOP-20 (DB) package: 7.5 mm × 5.6 mm body, 0.65 mm lead pitch, 2.0 mm max height. TI provides official land pattern, stencil design, and PCB layout recommendations at ti.com/sc/package - including solder mask defined pads, 0.125-mm stencil thickness guidance, and quadrant-specific pin-1 orientation for tape-and-reel placement.
How does V62/04738-01XE differ from the commercial SN74ABT245B part?
V62/04738-01XE is the radiation-hardened, extended-temperature derivative of SN74ABT245B. Key differences include: qualification to −55°C to 125°C (vs. −40°C to 85°C), controlled baseline manufacturing (single fab/assembly site), enhanced DMS support, and inclusion in TI's V62 military-grade product family. Electrical specs are identical, but V62/04738-01XE undergoes additional reliability screening per MIL-PRF-38535 requirements.
What are the absolute maximum ratings for V62/04738-01XE supply voltage and input voltage?
V62/04738-01XE has an absolute maximum supply voltage (VCC) of −0.5 V to 7 V and absolute maximum input voltage (VI) of −0.5 V to 7 V (except I/O ports). These ratings are specified in the SCBS798 datasheet Section "Absolute Maximum Ratings" and define stress limits beyond which permanent damage may occur - not recommended operating conditions. For reliable function, VCC must stay within 4.5 V to 5.5 V per recommended operating conditions.
