Texas Instruments V62/04708-01XE

Overview

V62/04708-01XE from Texas Instruments is a radiation-hardened, high-reliability 16-bit LVT H-level buffer/line driver with true outputs and active-low 3-state control, designed for 3.3-V VCC operation while interfacing to 5-V TTL systems. It delivers ±12 mA drive strength per output, integrates 22-Ω series resistors to suppress overshoot/undershoot, and supports hot insertion via Ioff and power-up 3-state logic in extended temperature (−40°C to 85°C) military-grade applications.

For engineers reviewing the V62/04708-01XE datasheet, V62/04708-01XE pinout, V62/04708-01XE application, or V62/04708-01XE equivalent, key selection criteria include mixed-mode 3.3-V/5-V signal compatibility, bus-hold input retention without external resistors, distributed VCC/GND for noise suppression, and qualification per enhanced DMS and JEDEC extended-temperature reliability standards.

Technical Context

This device implements four independent 4-bit noninverting buffers, each with symmetrical active-low OE control and flow-through pin architecture optimized for PCB layout. Each output stage includes integrated 22-Ω series termination and supports bidirectional current sourcing/sinking up to ±12 mA at VCC = 3.3 V.

It features bus-hold circuitry on all data inputs to maintain valid logic states when undriven, Ioff protection that disables outputs during power-down to prevent backflow, and power-up 3-state behavior ensuring high-impedance outputs during VCC ramp from 0 to 1.5 V - critical for hot-swap and system-level fault containment.

FAQ

What is the operating temperature range for V62/04708-01XE?

V62/04708-01XE is fully specified for operation from −40°C to +85°C, qualified per JEDEC and industry standards including temperature cycling, HAST, and autoclave testing. This extended range supports deployment in aircraft flight decks, satellite payloads, and ground-mobile defense systems where ambient conditions exceed commercial limits. The V62/04708-01XE maintains full electrical compliance across this entire range without derating.

Does V62/04708-01XE support hot insertion, and how is it implemented?

Yes, V62/04708-01XE supports hot insertion through dual mechanisms: Ioff circuitry disables outputs when VCC = 0 V to prevent damaging back-current flow, and power-up 3-state logic forces outputs into high-impedance during VCC ramp from 0 to 1.5 V. These features are validated per TI's hot-insertion application guidelines and ensure safe module replacement in live backplane systems without disrupting adjacent circuitry. The V62/04708-01XE meets these requirements without external components.

Can V62/04708-01XE interface directly with 5-V logic while powered at 3.3 V?

Yes, V62/04708-01XE accepts 5-V input signals while operating at 3.3-V VCC, enabling seamless TTL-to-LVT interfacing without level shifters. Its input voltage rating extends to 5.5 V, and VIH/VIL thresholds (2.0 V / 0.8 V) guarantee reliable recognition of 5-V logic levels. This capability is intrinsic to the V62/04708-01XE design and verified across temperature and voltage corners per the SCBS781 datasheet.

What packaging and marking does V62/04708-01XE use?

V62/04708-01XE is supplied in a 48-pin TSSOP (DGG) package with 0.5-mm pitch, RoHS-compliant NiPdAu lead finish, and moisture sensitivity level 1 (260°C peak reflow). Each unit is marked "LH162244EP" on the top surface, consistent with TI's V62 military-grade marking convention. The V62/04708-01XE is shipped in large tape-and-reel format (2000 units per reel) compliant with EIA-481-D standards.

How does the bus-hold feature on V62/04708-01XE eliminate external resistors?

The V62/04708-01XE integrates active bus-hold circuitry on all 16 data inputs, which detects and latches the last-valid logic state when inputs float or become undriven. This eliminates the need for external pullup or pulldown resistors - reducing BOM count, saving PCB area, and removing resistor-induced timing skew. The V62/04708-01XE's bus-hold current (±750 µA max) is sufficient to override typical leakage currents in high-impedance environments.
