Product details
Overview
V62/03607-01XE from Texas Instruments is a radiation-hardened, high-reliability octal 3-state noninverting buffer/driver IC designed for memory address and bus driving in extended-temperature aerospace and defense systems. It operates from −55°C to 125°C, supports 2-V to 6-V supply voltage, delivers ±35 mA output drive, and features 20-pin SOIC (DW) package with NIPDAU lead finish.
For engineers reviewing the V62/03607-01XE datasheet, V62/03607-01XE pinout, V62/03607-01XE application, or V62/03607-01XE equivalent, this page provides verified electrical specs, thermal performance data, JEDEC-qualified reliability pedigree, and precise pin-level functional mapping for mission-critical embedded timing and signal routing designs.
Technical Context
This device implements two independent 4-bit noninverting buffer sections, each with dedicated 3-state output-enable (OE) control. Each section passes A-inputs to Y-outputs when OE is low; outputs enter high-impedance state when OE is high - enabling bidirectional bus management without external logic.
It uses silicon-gate CMOS technology for low power consumption (ICC ≤ 160 µA at 6 V), rail-to-rail output swing (VOH ≥ 5.9 V, VOL ≤ 0.4 V at 6 V), and robust noise immunity (VIH = 4.2 V, VIL = 1.8 V at VCC = 6 V). Propagation delay is 11–29 ns across 2–6 V supply range with 50-pF load.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC244MDWREP | Same DW package and −55°C to 125°C rating, but commercial-grade qualification (not QML-V or V62) | Lacks radiation tolerance, DMS support, and MIL-PRF-38535 pedigree - unsuitable for space or nuclear applications | Select only for non-safety-critical industrial systems where cost outweighs long-term supply assurance |
| SN54HC244 | Military-grade (QML-38535 Class B), same pinout, but rated −55°C to 125°C with different screening flow and no V62 prefix | Approved for defense platforms but lacks V62's enhanced DMS tracking and controlled baseline documentation | Prefer V62/03607-01XE when full V62 pedigree, DMS reporting, and TI's extended product-change notification are contractually mandated |
Compared with SN74HC244MDWREP and SN54HC244, V62/03607-01XE uniquely combines QML-V qualification, controlled baseline manufacturing, and TI's V62-specific DMS and change notification protocols - making it the only option meeting DoD SAE AS6019 and NASA GSFC-8010 requirements for new spaceflight hardware.

FAQ
What is the maximum operating temperature range for V62/03607-01XE?
V62/03607-01XE is fully specified and qualified for continuous operation from −55°C to 125°C ambient temperature, per MIL-PRF-38535 Class V requirements. This range is validated through temperature cycling, biased 85/85, and HAST testing - ensuring reliability in spacecraft thermal vacuum and nuclear facility control room environments. The V62/03607-01XE datasheet confirms no derating is required across this full range.
Does V62/03607-01XE support 3.3-V logic interfaces?
Yes, V62/03607-01XE supports 3.3-V operation with guaranteed performance: at VCC = 3.3 V, VIH is 2.31 V (min), VIL is 1.09 V (max), and VOH/VOL meet 3.3-V LVTTL thresholds. Its 2-V to 6-V supply range allows direct interfacing with 3.3-V FPGAs and microcontrollers without level shifters. All switching characteristics in the V62/03607-01XE datasheet include 4.5-V test conditions relevant to 3.3-V systems.
Is V62/03607-01XE pin-compatible with standard SN74HC244 devices?
Yes, V62/03607-01XE uses the identical 20-pin SOIC (DW) package and exact pinout as SN74HC244MDWREP and SN74HC244QDWREP - including 1OE, 2OE, A/Y, B/Z, VCC, and GND assignments. However, due to its enhanced screening and qualification, V62/03607-01XE requires no PCB layout changes when replacing commercial HC244 variants in existing designs targeting extended temperature or radiation environments.
What JEDEC qualification standards apply to V62/03607-01XE?
V62/03607-01XE is qualified per JEDEC JESD22-A108 (HAST), JESD22-A104 (temperature cycling), JESD22-A110 (mechanical shock), and JESD22-A113 (biased 85/85), as documented in its MIL-PRF-38535 Class V pedigree. These tests verify reliability under extreme thermal, humidity, and mechanical stress - essential for V62/03607-01XE deployment in launch vehicle avionics and deep-space probe electronics.
How does V62/03607-01XE differ from SN54HC244 in terms of supply chain assurance?
V62/03607-01XE includes TI's Enhanced Diminishing Manufacturing Sources (DMS) support and enhanced product-change notification - features not present in SN54HC244. While both meet MIL-PRF-38535, V62/03607-01XE provides formal DMS reporting, controlled baseline documentation, and guaranteed 15-year minimum supply commitment, making it the preferred choice for programs requiring strict obsolescence risk mitigation per DoD Directive 5000.89.
