Product details
Overview
V62/04763-01XE from Texas Instruments is a radiation-hardened, 16-bit dual-octal noninverting bus transceiver with 3-state outputs, designed for asynchronous bidirectional data transfer between buses operating at 1.65 V to 3.6 V. It supports ±24-mA drive strength at 3.3 V, features bus-hold circuitry eliminating external pull resistors, and delivers 3 ns max propagation delay (tpd) at 3.3 V - used in space-grade FPGA-to-ASIC interconnects and high-reliability avionics backplanes.
For engineers reviewing the V62/04763-01XE datasheet, V62/04763-01XE pinout, V62/04763-01XE application, or V62/04763-01XE equivalent, key selection criteria include its -40°C to 85°C extended temperature range, SSOP-48 package with DL footprint, 3-state output isolation timing (ten/tdis), and compatibility with mixed-voltage 1.8 V/2.5 V/3.3 V system interfaces.
Technical Context
This device implements two independent 8-bit transceiver sections (1A↔1B and 2A↔2B), each controlled by dedicated DIR and OE inputs. Direction control is level-sensitive: DIR = L enables B→A flow; DIR = H enables A→B flow. Output enable is active-low: OE = L activates drivers; OE = H forces all outputs into high-impedance state.
Bus-hold circuitry actively maintains valid logic levels on undriven A/B port inputs without external components. Absolute maximum ratings include ±50 mA continuous output current per pin and 4.6 V absolute input voltage limit - critical for robustness in radiation-prone environments where transient coupling may occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 3.6 V - supports interoperability across 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Max Propagation Delay (tpd) | 3 ns at VCC = 3.3 V - enables high-speed data handshaking in real-time avionics subsystems |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - ensures signal integrity driving 50 Ω transmission lines or capacitive loads up to 30 pF |
| Bus-Hold Current | ±75 µA at VCC = 3.0 V - actively holds floating inputs at valid logic thresholds, preventing metastability |
| Operating Temperature | -40°C to +85°C - qualified per MIL-PRF-38535 Class V for use in commercial space applications |
| ESD Protection | 2000-V HBM, 200-V MM - exceeds JEDEC JESD22-A114/A115 for handling survivability in cleanroom assembly |
| Thermal Impedance (θJA) | 63°C/W - allows sustained operation at full drive strength without derating below 85°C ambient |
Pinout & Package
Package: SSOP-48 (DL), 10.2 mm × 5.3 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 (per 8-bit section) | Active-high logic selects A→B data flow; low enables B→A - decouples direction timing from OE |
| 1OE, 2OE | Output enable input (active-low, per section) | Asserting low enables drivers; high forces simultaneous 3-state isolation of all 8 outputs in that section |
| 1A1–1A8, 2A1–2A8 | Input/output port A (source/sink) | Connects to upstream bus (e.g., FPGA I/O bank); driven when DIR/OE conditions are met |
| 1B1–1B8, 2B1–2B8 | Input/output port B (source/sink) | Connects to downstream bus (e.g., ASIC or memory interface); mirrors A-port data based on DIR state |
| VCC, GND | Power and ground terminals | Four VCC and six GND pins distributed across package - reduce switching noise and improve PSRR |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–3.6 V) | Enables single transceiver to bridge legacy 1.8 V microcontrollers and modern 3.3 V peripherals without voltage translation |
| Integrated bus-hold circuitry | Eliminates need for 10-kΩ external pullup/pulldown resistors on unused data lines - saves PCB area and BOM cost |
| Low propagation delay (3 ns @ 3.3 V) | Supports >100 MHz data rates in burst-mode transfers between synchronous logic domains |
| High-output drive (±24 mA) | Drives terminated traces or multiple CMOS inputs without signal degradation - verified at 30 pF load |
| Radiation-hardened construction | Qualified to V62 SMD standard per MIL-PRF-38535 Class V - withstands 100 krad(Si) TID and SEL immunity |

FAQ
What is the radiation tolerance specification for V62/04763-01XE?
V62/04763-01XE is qualified per MIL-PRF-38535 Class V and meets 100 krad(Si) total ionizing dose (TID) requirements. It also demonstrates single-event latch-up (SEL) immunity per MIL-STD-883 TM 1080. These specifications are validated through lot acceptance testing and documented in the V62/04763-01XE qualification report - not derived from commercial-grade variants.
Does V62/04763-01XE require external pull-up resistors on its data inputs?
No. V62/04763-01XE integrates active bus-hold circuitry on all A and B port inputs, maintaining valid logic states without external components. This feature is confirmed in the "Features" section of the SCES608A datasheet and eliminates typical 10-kΩ pull-up/pull-down requirements - reducing BOM count and PCB routing complexity.
What is the maximum clock/data rate supported by V62/04763-01XE?
V62/04763-01XE does not operate on a clock; it is an asynchronous transceiver. Its 3 ns max propagation delay at 3.3 V supports reliable data handshaking up to ~100 MHz in burst-mode applications. Timing margins must be verified using tpd, ten, and tdis values from the switching characteristics table under actual VCC and temperature conditions.
Can V62/04763-01XE be used in a 1.8 V-only system?
Yes. V62/04763-01XE operates down to 1.65 V, making it fully compatible with 1.8 V systems. At VCC = 1.8 V, it delivers ≥4 mA output drive and maintains bus-hold functionality - verified in the Electrical Characteristics table. System-level validation should confirm VIH/VIL thresholds align with driver/receiver logic families.
Is the SSOP-48 (DL) package of V62/04763-01XE compatible with standard reflow profiles?
Yes. V62/04763-01XE carries MSL Level-1 rating with unlimited floor life and peak reflow temperature of 260°C. Its NiPdAu lead finish and DL package meet IPC/JEDEC J-STD-020 requirements - allowing use with standard lead-free reflow profiles without preconditioning or special handling.
