Product details

Overview

V62/04709-02YE from Texas Instruments is a 16-bit dual-octal noninverting 3-state transceiver optimized for 3.3-V V_CC operation with 5-V tolerant I/O, supporting mixed-mode signal interfacing between 3.3-V and 5-V buses. It features bus-hold circuitry, hot-insertion support via I_off and power-up 3-state, and integrated 22-Ω series resistors on A-port outputs. Used in military-grade backplane interface and FPGA-to-ASIC data bridging applications.

For engineers reviewing the V62/04709-02YE datasheet, V62/04709-02YE pinout, V62/04709-02YE application, or V62/04709-02YE equivalent, key selection criteria include its −55°C to 125°C extended temperature rating, SSOP-48 package with distributed V_CC/GND pins, 2.7–3.6-V supply range, and guaranteed 64-mA B-port sink current at 3 V.

Technical Context

This device implements a flow-through architecture with two independent 8-bit bidirectional data paths controlled by DIR and OE inputs per section. Each path supports direction-controlled data transmission (A↔B) with simultaneous isolation capability when OE is high.

It integrates active bus-hold on all data inputs to maintain valid logic states without external pull resistors, and uses distributed V_CC/GND pin placement to suppress high-speed switching noise. The A-port outputs embed 22-Ω series termination to reduce overshoot/undershoot, while I_off protection prevents backflow during partial power-down.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - Ensures stable operation across unregulated battery supplies down to 2.7 V.
Operating Temperature	−55°C to 125°C - Qualified per enhanced DMS and JEDEC HAST/temperature cycle standards for space/military use.
B-port I_OL	64 mA at V_CC = 3 V - Supports direct drive of heavy capacitive loads or multiple TTL inputs without buffering.
A-port Output Resistance	22 Ω series - Reduces signal ringing and EMI without requiring external termination components.
t_PLH/t_PHL (A→B)	1 ns min / 3.3 ns typ at V_CC = 3.3 V - Enables reliable 100+ MHz data transfer in synchronous bus interfaces.
I_off	±100 µA at V_CC = 0 V - Prevents damaging current backflow during hot insertion or partial system power-down.
Bus-Hold Current	±750 µA max at V_CC = 3.6 V - Maintains defined logic state on floating inputs without external biasing.

1B1–1B8, 2B1–2B8	B-port data I/O (input/output)	5-V tolerant side capable of sinking 64 mA; interfaces directly to legacy 5-V logic or peripherals.
V_CC (Pins 7, 18, 29, 40)	Power supply	Distributed V_CC pins minimize IR drop and supply noise across high-speed switching channels.
GND (Pins 4, 11, 22, 33, 44)	Ground reference	Five dedicated GND pins provide low-inductance return paths and reduce ground bounce (V_OLP < 0.8 V).

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional level-shifting transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CLVTH162245MDLREP	Same DL package, identical electrical specs, but commercial-temp (−40°C to 85°C) qualification and standard TI EP process.	Lacks extended temperature and enhanced DMS pedigree; not approved for space/military deployment.	Select only for non-critical industrial applications where cost and availability outweigh environmental ruggedness.
SN54LVTH162245	QML-38535 Class V qualified; same pinout and function but different screening, test flow, and lot traceability documentation.	Requires full QML procurement chain and DoD compliance reporting; higher unit cost and longer lead times.	Choose when formal QML certification and traceability to MIL-PRF-38535 Rev G are contractually mandated.

Compared with CLVTH162245MDLREP, V62/04709-02YE adds −55°C start-up capability and enhanced reliability testing; versus SN54LVTH162245, it offers identical military performance with streamlined V62 procurement and reduced documentation overhead.

FAQ

What is the maximum operating temperature range supported by V62/04709-02YE?

V62/04709-02YE is fully specified for operation from −55°C to 125°C. This extended range is validated through JEDEC-compliant temperature cycling, biased 85/85, and HAST testing per its enhanced qualification pedigree. The device maintains guaranteed timing and DC parameters across this full range, making it suitable for engine bay, avionics, and space payload applications where ambient extremes are routine. V62/04709-02YE achieves this via process and packaging enhancements beyond commercial-grade SN74LVTH162245 variants.

Does V62/04709-02YE support hot insertion, and how is it implemented?

Yes, V62/04709-02YE supports hot insertion via two complementary mechanisms: I_off circuitry disables outputs when V_CC = 0 V, preventing damaging current backflow into powered-down systems; and power-up 3-state ensures outputs remain in high-impedance until V_CC stabilizes above 1.5 V. These features are verified per JESD78 and applied in backplane and modular chassis designs. V62/04709-02YE's I_off is limited to ±100 µA, enabling safe connection to live 5-V buses without disrupting adjacent circuitry.

Can V62/04709-02YE interface directly between 3.3-V and 5-V logic without external components?

Yes, V62/04709-02YE supports mixed-mode signal operation: its A-port accepts 5-V inputs while operating from a 3.3-V V_CC, and its B-port drives 5-V logic levels with up to 64-mA sink current. No level-shifting resistors or translators are needed. The A-port's 22-Ω series resistance further eliminates external termination. V62/04709-02YE's absolute maximum input voltage of 7 V and 5.5-V VI rating ensure robustness against transient overvoltage during cross-voltage domain signaling.

What package type and lead finish does V62/04709-02YE use?

V62/04709-02YE uses the SSOP-48 (DL) package: 12.6 mm × 6.2 mm body, 0.5-mm pitch, gull-wing leads. Its lead finish is NiPdAu (nickel-palladium-gold), commonly referenced as NIPDAU in TI documentation, and it carries a moisture sensitivity level (MSL) rating of Level-1 (unlimited floor life at ≤30°C/60% RH). This package is optimized for high-density routing and thermal dissipation in conduction-cooled military PCBs. V62/04709-02YE's DL package matches the footprint of CLVTH162245MDLREP for design reuse.

How does the bus-hold feature on V62/04709-02YE eliminate external pull resistors?

V62/04709-02YE integrates active bus-hold circuitry on all A- and B-port data inputs, providing ±750 µA dynamic hold current at V_CC = 3.6 V to maintain valid logic states on undriven or floating lines. This eliminates the need for external pullup or pulldown resistors, reducing BOM cost, PCB area, and potential signal integrity issues from resistor parasitics. TI explicitly warns against combining bus-hold with external resistors, as it may cause contention. V62/04709-02YE's bus-hold behavior is characterized across −55°C to 125°C and is part of its enhanced military qualification.
