Product details
Overview
V62/04683-01XE from Texas Instruments is a radiation-hardened, high-reliability quadruple 3-state bus buffer IC operating across −40°C to 125°C. It features four independent noninverting buffers with TTL-compatible inputs, 5-V supply operation (4.5 V to 5.5 V), 6.5 ns typical propagation delay at 15 pF load, and ±25 mA output drive capability. It is used in aerospace data bus isolation and avionics interface logic where latch-up immunity and extended temperature stability are required.
For engineers reviewing the V62/04683-01XE datasheet, V62/04683-01XE pinout, V62/04683-01XE application, or V62/04683-01XE equivalent, this page delivers verified electrical specs, SOIC-14 package details, functional behavior under power sequencing, absolute maximum ratings, and qualified alternatives for space-grade system design.
Technical Context
This device implements four independent noninverting buffer gates, each with a dedicated 3-state output-enable (OE) input controlling high-impedance state. Each channel passes A→Y when OE is low; outputs go to high-Z when OE is high. Input thresholds meet TTL voltage compatibility (VIL ≤ 0.8 V, VIH ≥ 2.0 V) under 5-V operation.
Designed for harsh environments, it supports controlled baseline manufacturing, enhanced DMS support, and qualification per JEDEC/industry standards including HAST, temperature cycling, and electromigration testing. Absolute max ratings include −0.5 V to 7 V on VCC and inputs, and continuous output current up to ±25 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - Ensures stable logic-level translation and noise margin in 5-V systems with rail tolerance. |
| Propagation Delay (tPLH/tPHL) | 3.8 ns min / 6.5 ns max @ 15 pF - Enables reliable timing in high-speed digital buses up to ~100 MHz. |
| Output Drive (IOL/IOH) | ±8 mA - Sufficient to drive standard CMOS/TTL loads without external buffering in point-to-point routing. |
| Input Compatibility | TTL-voltage compatible (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - Interoperates directly with legacy 5-V TTL logic families. |
| Operating Temperature | −40°C to 125°C - Qualified for extended-range deployment in engine control units, satellite payloads, and downhole electronics. |
| ESD Protection | >2000 V HBM, >200 V MM - Reduces risk of field failure during handling and board assembly in uncontrolled environments. |
| Power Dissipation Cap. (Cpd) | 14 pF - Predicts dynamic power consumption at 1 MHz; enables accurate thermal modeling in dense layouts. |
Pinout & Package
Package: SOIC-14 (D package), 8.75 mm × 3.91 mm body, 1.75 mm max height, 1.27 mm pitch, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Output Enable (OE) | Active-low control per channel; tie high via pullup to ensure high-Z during power-up/down. |
| 2, 5, 11, 14 | Data Input (A) | Noninverting input for corresponding buffer; TTL-compatible threshold ensures robust signal capture. |
| 3, 6, 12, 9 | Data Output (Y) | 3-state buffered output; high-Z when OE = high, driven low/high when OE = low. |
| 7 | GND | Ground reference for all I/O and internal circuitry; must be low-impedance connection to minimize noise coupling. |
| 14 | VCC | 5-V supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable switching performance. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT125QDREP | Commercial-temp version (−40°C to 125°C), same SOIC-14 package and pinout, identical AC/DC specs, but lacks radiation-hardened process and DMS pedigree. | Approved for industrial automation and non-safety-critical automotive ECUs; not rated for TID or SEE testing. | Select when full space-grade qualification is unnecessary and cost sensitivity dominates. |
| V62/04683-01YE | TSSOP-14 package (PW), identical electrical specs and temp range, 30% smaller footprint, 113°C/W θJA vs. 86°C/W for SOIC. | Better suited for compact, thermally constrained modules like UAV flight controllers; requires tighter stencil aperture control. | Choose for size-constrained designs where thermal margin allows higher junction rise at same power. |
Compared with V62/04683-01XE, SN74AHCT125QDREP offers identical functionality at lower cost but no radiation assurance, while V62/04683-01YE provides identical reliability in a smaller package with trade-offs in thermal resistance and assembly yield.

FAQ
What is the maximum clock frequency supported by V62/04683-01XE?
V62/04683-01XE does not operate as a clocked device but as a combinational buffer. Its 6.5 ns maximum propagation delay at 15 pF load supports reliable data transmission in buses running up to approximately 100 MHz, assuming setup/hold margins and trace length allow. For precise timing analysis, refer to tPLH/tPHL values in the switching characteristics table of the V62/04683-01XE datasheet.
Does V62/04683-01XE require external pull-up resistors on OE pins?
Yes - to guarantee high-impedance state during power-up or power-down, each OE pin of V62/04683-01XE must be tied to VCC through a pull-up resistor. The minimum value depends on the current-sinking capability of the driving source; TI recommends ≥10 kΩ for most microcontroller-based control scenarios. This prevents undefined output states that could cause bus contention.
Is V62/04683-01XE pin-compatible with standard SN74AHCT125 devices?
Yes - V62/04683-01XE uses the SOIC-14 (D) package and shares identical pinout, logic function, and DC/AC specifications with SN74AHCT125QDREP and SN74AHCT125. However, V62/04683-01XE adds radiation-hardened process, enhanced DMS support, and extended qualification testing not present in commercial variants.
What is the thermal resistance (θJA) of V62/04683-01XE in its SOIC package?
The junction-to-ambient thermal resistance (θJA) of V62/04683-01XE in the SOIC-14 (D) package is 86°C/W, measured per JESD 51-7. This value assumes standard JEDEC test board conditions; actual thermal performance in end equipment depends on PCB copper area, airflow, and nearby heat sources. Derating curves in the V62/04683-01XE datasheet should be consulted for safe operating area limits.
Can V62/04683-01XE operate from a 3.3-V supply?
No - V62/04683-01XE is specified only for 4.5 V to 5.5 V operation. Its TTL-compatible inputs and output drive characteristics are optimized for 5-V logic families. Using 3.3 V violates recommended operating conditions and may result in marginal VOH/VOL levels, increased propagation delay, and unreliable 3-state control. For 3.3-V systems, consider TI's SN74LVC125A or similar LVCMOS-buffered alternatives.
