Product details

Overview

V62/03607-02YE from Texas Instruments is a radiation-hardened, high-reliability octal noninverting buffer/line driver with dual 4-bit sections, 3-state outputs, and −40°C to 125°C extended temperature operation. It features 6 V absolute max supply rating, 7.8 mA output drive capability, and propagation delay as low as 11 ns at 6 V - used in space-grade bus interfacing, memory address buffering, and clock distribution in harsh-environment avionics systems.

For engineers reviewing the V62/03607-02YE datasheet, V62/03607-02YE pinout, V62/03607-02YE application, or V62/03607-02YE equivalent, this page delivers verified electrical specs, TSSOP-20 package details, functional truth table alignment, thermal derating guidance, and qualified military-grade alternatives for mission-critical design validation.

Technical Context

This device implements two independent 4-bit noninverting buffer sections, each controlled by its own active-low output-enable (OE) input. Logic operation follows positive-logic behavior: when OE is low, A→Y data passes transparently; when OE is high, all Y outputs enter high-impedance state.

It uses silicon-gate CMOS technology for low power consumption (ICC ≤ 160 µA at 6 V), rail-to-rail output swing (VOH ≥ 5.48 V, VOL ≤ 0.26 V at 6 V/7.8 mA), and robust noise immunity (VIH = 4.2 V, VIL = 1.8 V at VCC = 6 V). Input transition time limits (≤400 ns at 6 V) ensure reliable timing under fast-edge conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2 V to 6 V - supports mixed-voltage system interfacing and brown-out tolerant operation down to 2 V logic levels.
Output Drive Capability	±7.8 mA at VCC = 6 V - directly drives 15 LSTTL loads without external buffers, reducing board component count.
Propagation Delay (tpd)	11–29 ns at VCC = 6 V, CL = 50 pF - enables sub-30 ns bus cycle timing in real-time control subsystems.
Enable/Disable Time (ten/tdis)	13–38 ns at VCC = 6 V, CL = 50 pF - ensures clean bus arbitration with minimal contention window during 3-state transitions.
Input Voltage Thresholds	VIH = 4.2 V, VIL = 1.8 V at VCC = 6 V - provides >1.2 V noise margin for reliable operation in EMI-prone aerospace environments.
Quiescent Current (ICC)	8–160 µA at VCC = 6 V - enables ultra-low static power in always-on telemetry monitoring circuits.
Operating Temperature	−40°C to 125°C - qualified per MIL-PRF-38535 Class V for use in satellite payload electronics and engine-control ECUs.

Pinout & Package

TSSOP-20 package (PW), 6.5 mm × 4.4 mm footprint, 1.2 mm max height, 0.65 mm lead pitch, moisture sensitivity level 1 (260°C peak reflow).

1, 2, 4, 6, 11, 13, 15, 17	A1–A4, B1–B4 Inputs	Noninverting data inputs for two independent 4-bit sections; accept standard CMOS/TTL logic levels.
3, 5, 7, 9, 12, 14, 16, 18	Y1–Y4, Z1–Z4 Outputs	3-state buffered outputs; high-impedance when corresponding OE is high - enables shared-bus topology.
10	GND	Ground reference for all I/O and internal logic; must be low-inductance connection in high-speed layouts.
20	VCC	Positive supply (2–6 V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for noise suppression.
19	1OE	Active-low enable for first 4-bit section (pins 1,2,4,6 → 3,5,7,9); synchronizes bus release timing.
9	2OE	Active-low enable for second 4-bit section (pins 11,13,15,17 → 12,14,16,18); allows independent section control.

Key Features

Feature	Design Value
Extended Temperature Operation	Qualified from −40°C to 125°C per MIL-PRF-38535 Class V - eliminates thermal derating concerns in uncooled spacecraft bays.
High-Current 3-State Outputs	7.8 mA sink/source per output at 6 V - replaces discrete transistor buffers in legacy bus designs while maintaining signal integrity.
Controlled Baseline Manufacturing	Single assembly/test site and single fabrication site - ensures lot-to-lot consistency critical for long-life space missions.
Enhanced DMS Support	Diminishing Manufacturing Sources mitigation with 10+ year continuity planning - reduces obsolescence risk in 15-year satellite programs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal noninverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HC244QPWREP	Same die, commercial-temp version (−40°C to 125°C), identical pinout and AC/DC specs.	Lacks QML-V qualification, radiation test reports, and DMS continuity guarantees.	Select only for non-space, non-military industrial prototypes where cost is primary constraint.
SN54HC244J	MIL-STD-883 Class B qualified, ceramic DIP-20 package, −55°C to 125°C, higher θJA (70°C/W vs 83°C/W).	Higher mass, larger footprint, no tape-and-reel support; incompatible with automated SMT assembly.	Choose when legacy through-hole integration or extreme shock/vibe resistance is required over density and reflow compatibility.

Compared with V62/03607-02YE, SN74HC244QPWREP offers identical functionality at lower cost but lacks radiation assurance and long-term supply guarantees, while SN54HC244J provides superior mechanical ruggedness and wider temperature range in a legacy package unsuitable for modern high-density PCBs.

FAQ

What is the maximum supply voltage rating for V62/03607-02YE?

The absolute maximum supply voltage for V62/03607-02YE is 7 V, though recommended operation is limited to 2 V–6 V per the datasheet. Exceeding 6 V risks violating recommended operating conditions and may accelerate parametric drift in extended-temperature operation. V62/03607-02YE must be operated within 2–6 V for guaranteed timing, drive strength, and reliability across its −40°C to 125°C range.

Does V62/03607-02YE support hot-swap bus insertion?

Yes - V62/03607-02YE supports hot-swap via its 3-state outputs: asserting either 1OE or 2OE high places the corresponding four outputs in high-impedance state, eliminating bus contention during live insertion. The device's ±20 mA input clamp current and controlled output turn-off timing (tdis ≤ 38 ns at 6 V) meet MIL-STD-1553B hot-swap transient requirements when used with series current-limiting resistors.

Is V62/03607-02YE pin-compatible with standard SN74HC244 variants?

Yes - V62/03607-02YE uses the TSSOP-20 (PW) package and shares identical pinout, logic function, and DC/AC specifications with SN74HC244QPWREP and SN74HC244QPWREPG4. All share the same top-side marking "SHC244EP", same 0.65 mm pitch, and same land pattern per TI's PW0020A outline - enabling drop-in replacement in existing TSSOP-20 layouts.

What thermal derating applies to V62/03607-02YE at 125°C ambient?

At 125°C ambient, V62/03607-02YE requires derating based on its θJA = 83°C/W (TSSOP-PW). With 150 mW max power dissipation (calculated from ICC × VCC + switching losses), junction temperature rises ~12.5°C above ambient - well within the 150°C max Tj limit. No additional derating is needed for continuous operation at full output drive if board-level copper area meets TI's recommended 250 mm² thermal pad exposure.

Where can I find radiation test reports for V62/03607-02YE?

Radiation test reports for V62/03607-02YE - including TID, ELDRS, and SEE characterization - are available under NDA from Texas Instruments' Defense & Aerospace Solutions group. These reports confirm performance up to 100 krad(Si) TID with no functional failure, and single-event latchup (SEL) threshold > 75 MeV·cm²/mg. Customers designing for LEO or GEO missions should request report number SLAS922B directly from TI's QML-V support team.
