Product details
Overview
V62/05612-01YE from Texas Instruments is a 16-bit dual-octal noninverting level-shifting transceiver supporting bidirectional voltage translation between 2.5 V/3.3 V (A port) and 3.3 V/5 V (B port), with 3-state outputs, ±24-mA drive at 3.3 V, and 5.8 ns max propagation delay - used in mixed-voltage FPGA-to-ASIC interconnects and industrial controller backplanes.
For engineers reviewing the V62/05612-01YE datasheet, V62/05612-01YE pinout, V62/05612-01YE application, or V62/05612-01YE equivalent, key selection criteria include dual-supply rail independence (VCCA/VCCB), direction-control logic referenced to VCCA, latch-up immunity >250 mA, and operation across –40°C to +85°C for extended-temperature embedded systems.
Technical Context
The V62/05612-01YE implements two independent 8-bit transceiver sections (1A↔1B and 2A↔2B), each with dedicated DIR and OE controls powered by VCCA. Signal translation occurs asynchronously without internal clocking or timing constraints.
Control inputs (1DIR, 2DIR, 1OE, 2OE) are referenced to VCCA, enabling robust interface with 2.5 V/3.3 V logic domains, while I/O ports tolerate VCCA + 0.5 V (A-side) and VCCB + 0.5 V (B-side) input voltages - critical for hot-swap and power-sequence-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 16-bit dual-octal bidirectional level-shifting transceiver with 3-state outputs |
| VCCA Range | 2.3 V to 3.6 V - powers control logic and A-port I/O; defines VIH/VIL thresholds |
| VCCB Range | 3 V to 5.5 V - powers B-port I/O; supports legacy 5 V TTL and modern 3.3 V systems |
| tpd (Max) | 5.8 ns at VCCA = 3.3 V, VCCB = 5 V - enables high-speed data handshaking in real-time control loops |
| Output Drive | ±24 mA at 3.3 V - drives standard CMOS loads with margin for trace capacitance and fanout |
| Operating Temp | –40°C to +85°C - qualified per MIL-PRF-38535 Class V for industrial and avionics subsystems |
| Latch-up Immunity | >250 mA per JESD 17 - prevents destructive latch-up during supply sequencing or ESD events |
Pinout & Package
TSSOP-48 (DGG) package: 12.6 mm × 6.2 mm × 1.2 mm body, 0.5 mm pitch, gull-wing leads, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active-high) | Defines data flow: DIR = L → B→A; DIR = H → A→B; referenced to VCCA |
| 1OE, 2OE | Output-enable input (active-low) | Drives all 8 associated outputs into high-Z when high; tied to VCCA via pullup for power-up safety |
| 1A1–1A8, 2A1–2A8 | A-port I/O terminals | 2.5 V/3.3 V domain signals; VIH/VIL defined relative to VCCA; tolerate up to VCCA + 0.5 V |
| 1B1–1B8, 2B1–2B8 | B-port I/O terminals | 3.3 V/5 V domain signals; VIH/VIL defined relative to VCCB; tolerate up to VCCB + 0.5 V |
| VCCA | A-port and control logic supply | Powers DIR/OE inputs and A-side buffers; must be stable before VCCB during power-up |
| VCCB | B-port supply | Powers B-side buffers only; may ramp after VCCA to avoid contention |
| GND (×10) | Ground reference | Multiple distributed GND pins minimize ground bounce across 16-bit bus switching |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCCA (2.3–3.6 V) and VCCB (3–5.5 V) enable simultaneous interfacing of 2.5 V FPGAs and 5 V peripherals |
| Control-input voltage referencing | All DIR/OE inputs referenced to VCCA - eliminates need for level shifters on control lines |
| High noise immunity | VIH/VIL thresholds scale with VCCA/VCCB; 0.7×VCC low-level threshold prevents false triggering in noisy environments |
| Power-up robustness | OE tied to VCCA ensures outputs remain high-Z until both supplies stabilize - prevents bus contention |
| Extended temperature qualification | MIL-PRF-38535 Class V screening - validated for –40°C to +85°C operation with full parametric guarantee |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level-shifting transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16T245 | Single-supply (1.2–3.6 V), no VCCB rail; lower drive (±12 mA); 3.5 ns tpd | Suitable only for 1.8 V ↔ 3.3 V translation; lacks 5 V tolerance | Select when interfacing ultra-low-voltage SoCs where 5 V compatibility is unnecessary |
| TXB0108PWR | Auto-direction sensing; no DIR pins; 1.2–3.6 V I/O; ±20 mA drive; 5.2 ns tpd | Eliminates external direction control but adds latency uncertainty during bus turnaround | Prefer for I²C/SPI buses with frequent bidirectional transitions; avoid for deterministic timing-critical parallel buses |
Compared with SN74AVC16T245 and TXB0108PWR, V62/05612-01YE uniquely supports 5 V B-port operation with explicit DIR control and MIL-spec temperature range - making it the only choice for deterministic, high-drive, mixed-voltage industrial and avionics backplanes.

FAQ
What voltage levels does the V62/05612-01YE support on its A and B ports?
The V62/05612-01YE supports 2.3 V to 3.6 V on the A port (VCCA) and 3 V to 5.5 V on the B port (VCCB). This allows reliable bidirectional translation between 2.5 V/3.3 V logic and 3.3 V/5 V systems. The V62/05612-01YE datasheet specifies absolute maximum ratings up to VCCA + 0.5 V and VCCB + 0.5 V on respective I/O pins.
Is the V62/05612-01YE pin-compatible with commercial-grade SN74ALVC164245 variants?
Yes - the V62/05612-01YE uses the TSSOP-48 (DGG) package with identical pinout and footprint to CALVC164245IDGGREP and SN74ALVC164245. All signal, power, and ground assignments match exactly, enabling drop-in replacement in existing designs requiring extended temperature or enhanced product qualifications.
How should OE and DIR pins be handled during power-up to ensure safe operation of the V62/05612-01YE?
TI recommends tying OE to VCCA via a pullup resistor so it ramps with VCCA, and powering VCCA before VCCB. DIR may be held low (for B→A default) or ramped with VCCA if A→B direction is required at startup. This sequence prevents bus contention and ensures high-Z outputs until both supplies stabilize. The V62/05612-01YE design inherently supports this behavior due to VCCA-referenced control inputs.
Does the V62/05612-01YE require external level shifters for its control inputs?
No - all control inputs (1DIR, 2DIR, 1OE, 2OE) are referenced to VCCA, meaning they operate natively at the A-port voltage domain. When VCCA = 2.5 V or 3.3 V, those inputs accept standard 2.5 V/3.3 V logic levels without additional translation circuitry. This simplifies system design and reduces component count compared to solutions requiring separate control-line level shifters.
What is the latch-up immunity rating for the V62/05612-01YE, and how is it verified?
The V62/05612-01YE exceeds 250 mA latch-up immunity per JESD 17, verified through standardized stress testing including biased 85/85, temperature cycling, and HAST. This rating applies across the full –40°C to +85°C operating range and is part of its MIL-PRF-38535 Class V qualification - ensuring robust operation in electrically noisy industrial and avionics environments where transient-induced latch-up is a critical failure mode. The V62/05612-01YE maintains this performance without derating.
