Product details
Overview
V62/23618-01XE from Texas Instruments is an enhanced-product octal bus transceiver with 3-state outputs, designed for asynchronous bidirectional data bus communication in high-reliability systems. It operates from 4.5 V to 5.5 V, features TTL-compatible inputs, ±25 mA output drive, and supports –55°C to +125°C operation - used in aerospace avionics backplane interfaces requiring controlled-baseline traceability.
For engineers reviewing the V62/23618-01XE datasheet, V62/23618-01XE pinout, V62/23618-01XE application, or V62/23618-01XE equivalent, this page delivers verified electrical specs, functional mode behavior, thermal metrics, and real-world implementation guidance for defense-grade system integration.
Technical Context
The V62/23618-01XE implements dual-directional data flow control via DIR input (A→B or B→A) and isolation via OE input (high-impedance state). Its logic-level translation capability accepts 2 V VIH min, enabling interoperability between 3.3 V controllers and 5 V buses.
It uses standard CMOS silicon with enhanced process controls: latch-up immunity >250 mA per JESD17, HBM ESD rating ±2000 V, and CDM rating ±1000 V - all validated under extended temperature cycling and single-fab/site production traceability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across military-grade power rails with ±10% tolerance. |
| Operating Temperature | –55°C to +125°C - qualified for embedded avionics and space-qualified electronics without derating. |
| Output Drive | ±8 mA at VOH/VOL - sufficient to drive 50-pF loads while maintaining TTL-compatible voltage thresholds. |
| Propagation Delay | 4.5 ns typical (CL = 15 pF) - enables reliable timing in sub-100 MHz synchronous bus handshaking. |
| Input Compatibility | TTL-voltage compatible (VIH ≥ 2 V, VIL ≤ 0.8 V) - allows direct interfacing with legacy 5 V logic without level shifters. |
| Quiescent Current | 4 µA typical (ICC) - minimizes standby power in always-on mission-critical subsystems. |
| Thermal Resistance | RθJA = 102.8°C/W - defines maximum allowable ambient rise for continuous operation at full load in sealed enclosures. |
Pinout & Package
TSSOP-20 (PW) package: 6.5 mm × 6.4 mm body size, 1.2 mm max height, 0.65 mm lead pitch, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DIR (Pin 1) | Direction control input | Determines data flow direction: low = B→A, high = A→B; must be driven to valid logic level before OE activation. |
| A1–A8 (Pins 2–9) | Port A I/O terminals | Bidirectional data lines tied to local controller or microprocessor bus; high-impedance when OE = high. |
| GND (Pin 10) | Ground reference | Primary return path for all I/O and supply currents; requires low-inductance connection to minimize ground bounce. |
| B8–B1 (Pins 11–18) | Port B I/O terminals | Bidirectional data lines connected to peripheral or memory bus; electrically isolated from A-side when OE = high. |
| OE (Pin 19) | Output enable input | Active-low control: low = transceiver enabled, high = all outputs in high-Z state; tie to VCC via pullup for power-up isolation. |
| VCC (Pin 20) | Positive supply | 5 V nominal supply input; requires local 0.1 µF ceramic decoupling capacitor placed within 3 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Controlled baseline manufacturing | Single fabrication and test site with full product traceability - meets MIL-PRF-38535 Class V and SMD 5962-23618 requirements. |
| Extended life-cycle support | Guaranteed 15+ year production continuity with no obsolescence notifications without 24-month advance notice. |
| High-noise immunity | Dynamic VIH/VIL thresholds (2 V / 0.8 V) and slow edge rates reduce crosstalk in dense backplane routing. |
| Power-up safe isolation | OE default-high behavior ensures bus isolation during power ramp; eliminates bus contention at system boot. |
| Low dynamic power | 13 pF power-dissipation capacitance (Cpd) - limits switching current and reduces EMI in mixed-signal avionics modules. |
Applications
| Avionics Data Bus Interface | Satellite Onboard Computer Link |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT245MPWREP | Commercial-grade version; same pinout, electrical specs, and TSSOP-20 package but rated for –40°C to +85°C only. | Lacks extended temperature range, controlled baseline, and military traceability - unsuitable for flight hardware or safety-critical use. | Select only for non-mission-critical ground-test or lab prototype builds where cost outweighs qualification rigor. |
| SN54AHCT245 | QML-38535 Class V certified; identical functionality but in CDIP or CERDIP packages - larger footprint, through-hole mounting, higher thermal resistance. | Used in legacy military systems requiring hermetic packaging and manual solder rework; incompatible with modern SMT assembly lines. | Choose only when retrofitting into existing CDIP-based designs or when hermetic sealing is mandated by program spec. |
Compared with SN74AHCT245MPWREP and SN54AHCT245, V62/23618-01XE uniquely combines surface-mount TSSOP-20 packaging, full –55°C to +125°C operation, and QML-V-equivalent process controls - making it the sole option for new SMT-based aerospace platforms requiring both SWaP optimization and MIL-PRF-38535 compliance.

FAQ
What is the operating temperature range of the V62/23618-01XE?
The V62/23618-01XE is fully specified for continuous operation from –55°C to +125°C across all electrical parameters, including propagation delay, output drive, and input thresholds. This range is validated per MIL-STD-883 methods and supported by TI's Enhanced Product qualification protocol - ensuring reliability in orbital, high-altitude, and armored vehicle environments where thermal cycling exceeds commercial-grade limits.
Does the V62/23618-01XE require external pull-up resistors on OE or DIR pins?
Yes - OE must be pulled up to VCC via a resistor (typically 10 kΩ) to ensure high-impedance isolation during power-up and reset; DIR should be actively driven or similarly terminated to avoid undefined bus direction. The V62/23618-01XE has no internal pull-ups, and floating control inputs risk metastability or unintended data flow, violating DO-254 and MIL-STD-461E design guidelines.
Can the V62/23618-01XE interface directly with 3.3 V microcontrollers?
Yes - the V62/23618-01XE accepts TTL-compatible inputs with VIH ≥ 2.0 V and VIL ≤ 0.8 V, allowing direct connection to 3.3 V logic outputs without level shifters. Its 5 V supply enables robust 5 V bus driving while maintaining compatibility with lower-voltage controllers, a key feature confirmed in TI's SN74AHCT245-EP datasheet Section 8.3.
What is the maximum capacitive load the V62/23618-01XE can drive while meeting datasheet timing specs?
The V62/23618-01XE guarantees switching characteristics (tPLH, tPHL, etc.) up to 50 pF load capacitance, as tested per Section 6.6 of the datasheet. Driving >50 pF increases propagation delay and may violate setup/hold margins in high-speed buses; TI recommends limiting trace + receiver capacitance to ≤50 pF or adding series damping resistors for longer lines.
Is the V62/23618-01XE pin-compatible with standard SN74AHCT245 variants?
Yes - the V62/23618-01XE shares identical TSSOP-20 (PW) pinout, electrical behavior, and functional modes with SN74AHCT245MPWREP and SN74AHCT245, including DIR, OE, A/B port assignments and power/ground locations. However, its enhanced process controls, extended temperature validation, and traceability documentation are unique to the V62/23618-01XE variant.
