Product details
Overview
CLVTH16245AIDGVREP from Texas Instruments is a radiation-hardened, high-reliability 16-bit noninverting bus transceiver with 3-state outputs, designed for 3.3-V ABT operation in extended temperature (–40°C to 85°C) and harsh environments. It supports bidirectional data flow between A and B buses via DIR control, features Ioff and power-up 3-state for hot insertion, and includes bus-hold circuitry eliminating external pullup/pulldown resistors. Used in space-grade avionics backplanes and military communication subsystems.
For engineers reviewing the CLVTH16245AIDGVREP datasheet, CLVTH16245AIDGVREP pinout, CLVTH16245AIDGVREP application, or CLVTH16245AIDGVREP equivalent, key selection criteria include its dual-octal 3-state architecture, 2.7–3.6-V VCC range, mixed-mode 5-V-tolerant inputs, and TVSOP (DGV) 48-pin package qualified per enhanced product standards.
Technical Context
The CLVTH16245AIDGVREP implements two independent 8-bit transceiver sections sharing common direction (DIR) and output-enable (OE) controls per section. Its Advanced BiCMOS Technology (ABT) enables low static power dissipation while maintaining TTL-compatible thresholds at 3.3-V supply.
It features distributed VCC/GND pins to suppress high-speed switching noise, flow-through pinout for optimized PCB routing, and active bus-hold on all A/B port inputs-ensuring stable logic states without external biasing. Ioff protection disables outputs during power-down to prevent backflow current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V with full functionality |
| IOH / IOL | –32 mA / 64 mA at VCC = 3.3 V - drives heavy capacitive loads and standard TTL inputs |
| tPLH / tPHL | Typ. 3.3 ns at VCC = 3.3 V, CL = 50 pF - enables high-speed 16-bit data transfer in timing-critical interconnects |
| VIH / VIL | 2.0 V / 0.8 V - compatible with 5-V CMOS/TTL logic levels while powered from 3.3 V |
| Bus-Hold Current | ±750 µA - maintains valid logic state on floating inputs without external resistors |
| Ioff Leakage | ±100 µA at VI/VO = 0–4.5 V - prevents damaging current flow during hot-swap or partial power-down |
| Operating Temp | –40°C to +85°C - qualified for industrial and extended-temperature embedded systems |
Pinout & Package
CLVTH16245AIDGVREP uses a 48-pin TVSOP (DGV) package measuring 12.5 mm × 6.1 mm × 1.2 mm max height, with gull-wing leads and JEDEC MO-153 compliance. Pin 1 marked by corner chamfer; lead finish is NiPdAu.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (per 8-bit section) | High = A→B data flow; Low = B→A data flow; enables bidirectional isolation |
| 1OE, 2OE | Output-enable input (per 8-bit section) | Low = outputs active; High = outputs in high-impedance state for bus isolation |
| 1A1–1A8, 2A1–2A8 | Data inputs (A-side ports) | Accept 5-V-tolerant signals; bus-hold active when floating |
| 1B1–1B8, 2B1–2B8 | Data outputs (B-side ports) | 3-state outputs with 2.7–3.6-V swing; support mixed-voltage system interfacing |
| VCC (Pins 7, 18, 29, 40) | Power supply | Distributed VCC pins minimize simultaneous switching noise across 16-bit bus |
| GND (Pins 4, 11, 22, 33, 44) | Ground reference | Five GND pins ensure low-impedance return path and reduce ground bounce (VOLP < 0.8 V) |
Key Features
| Feature | Design Value |
|---|---|
| Hot-insertion support | Ioff and power-up 3-state prevent backflow current and driver conflict during live board insertion |
| Mixed-mode voltage interface | 5-V-tolerant inputs and 3.3-V outputs enable seamless bridging between legacy 5-V and modern low-voltage subsystems |
| Bus-hold circuitry | Eliminates need for 10-kΩ external pullup/pulldown resistors on all A/B port inputs, reducing BOM count and layout area |
| Flow-through architecture | A/B port pins aligned top-to-bottom (e.g., 1A1 ↔ 1B1) simplifies layer routing and minimizes trace skew in high-speed layouts |
| Distributed power/ground | Four VCC and five GND pins suppress simultaneous switching noise, critical for signal integrity in 16-bit parallel buses |
Applications
| Avionics Data Bus Interface | Military Radios Backplane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVTH16245AQDGGREP | Same ABT core, identical pinout and specs, but rated for –40°C to 125°C and catalog-grade (non-EP) qualification | Suitable for commercial/industrial high-temp applications; lacks EP-level DMS support and enhanced pedigree documentation | Select when extended temperature range is required but space/military pedigree is not mandated |
| SN74LVC16245ADGGR | Lower drive strength (24 mA sink/source), no bus-hold, 1.65–3.6-V VCC, no Ioff or hot-insertion support | Cost-optimized for benign environments; requires external pullups and cannot be hot-inserted | Select only for non-critical, cost-sensitive consumer or lab prototypes where reliability and mixed-voltage tolerance are secondary |
Compared with SN74LVTH16245AQDGGREP, CLVTH16245AIDGVREP trades higher temperature range for enhanced product pedigree and DMS support; versus SN74LVC16245ADGGR, it delivers superior noise immunity, bus-hold autonomy, and system-level robustness at higher BOM cost.

FAQ
What is the maximum data rate supported by CLVTH16245AIDGVREP?
The CLVTH16245AIDGVREP does not specify a maximum data rate in MHz, but its typical propagation delays (tPLH/tPHL = 3.3 ns at VCC = 3.3 V, CL = 50 pF) support reliable operation up to ~150 Mbps in point-to-point 16-bit parallel links. System-level timing must account for board trace delays, load capacitance, and setup/hold margins. The CLVTH16245AIDGVREP's 10 ns/V input transition rate limit further constrains usable edge rates in high-noise environments.
Does CLVTH16245AIDGVREP require external pullup resistors on its A/B port inputs?
No. CLVTH16245AIDGVREP integrates active bus-hold circuitry on all A and B port inputs, maintaining valid logic states without external pullup or pulldown resistors. Using external resistors with the CLVTH16245AIDGVREP's bus-hold feature is explicitly discouraged in the datasheet, as it may cause contention or excessive current draw. This reduces BOM count and improves reliability in floating-input scenarios.
Can CLVTH16245AIDGVREP operate with a 2.5-V supply?
No. CLVTH16245AIDGVREP is specified for VCC between 2.7 V and 3.6 V per its Recommended Operating Conditions. Operation below 2.7 V violates the absolute minimum supply rating and risks undefined logic behavior, increased propagation delay, and failure to meet VOL/VOH specifications. For 2.5-V systems, consider TI's SN74LVC16245A or similar LVC-family devices.
Is CLVTH16245AIDGVREP pin-compatible with standard SN74LVTH16245A packages?
Yes - CLVTH16245AIDGVREP uses the same 48-pin TVSOP (DGV) footprint and pinout as the commercial SN74LVTH16245AQDGGREP and SN74LVTH16245AIDGV. All share identical terminal assignments, including DIR, OE, A/B port mapping, and distributed VCC/GND pin locations. Mechanical dimensions and solder paste stencil recommendations also match per TI's DGG0048A package drawing.
What is the meaning of "-EP" in CLVTH16245AIDGVREP?
The "-EP" suffix denotes Texas Instruments' Enhanced Product qualification level: a controlled-baseline manufacturing flow with single assembly/test/fab site, enhanced DMS (Diminishing Manufacturing Sources) support, full qualification pedigree per JEDEC/industry standards (including HAST, temperature cycling, and electromigration testing), and extended reliability reporting. CLVTH16245AIDGVREP meets these requirements for high-integrity applications where long-term supply stability and proven field reliability are mandatory.
