Product details
Overview
CLVTH16245AQDGGRQ1 from Texas Instruments is an automotive-qualified 16-bit noninverting 3-state transceiver in TSSOP-48 package, operating at 2.7–3.6 V VCC with 5-V tolerant inputs/outputs, 64 mA IOL drive, and bus-hold on all data inputs-designed for bidirectional data bridging between 3.3-V logic and legacy 5-V buses in engine control units.
For engineers reviewing the CLVTH16245AQDGGRQ1 datasheet, CLVTH16245AQDGGRQ1 pinout, CLVTH16245AQDGGRQ1 application, or CLVTH16245AQDGGRQ1 equivalent, key selection criteria include hot-insertion support via Ioff and power-up 3-state, mixed-voltage interface capability, and automotive-grade −40°C to 125°C operation with latch-up immunity >500 mA.
Technical Context
This device implements dual-octal flow-through architecture with independent DIR and OE controls per 8-bit section, enabling simultaneous A→B and B→A data paths or unified 16-bit operation. It uses Advanced BiCMOS Technology (ABT) for low static power and high-speed switching noise suppression via distributed VCC/GND pins.
Bus-hold circuitry actively maintains valid logic states on undriven inputs without external resistors, while Ioff protection prevents backflow current during power-down. The device enters high-impedance state when VCC drops below 1.5 V or when OE is asserted high.
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 in automotive environments |
| IOL / IOH | 64 mA / −32 mA - drives heavy capacitive loads and interfaces directly with TTL-level receivers |
| tPLH / tPHL | Max 4.5 ns at VCC = 3.3 V - enables reliable 200+ MHz bus operation with tight timing margins |
| VI Input Range | −0.5 V to 5.5 V - accepts 5-V logic signals while powered from 3.3-V rail, eliminating level shifters |
| θJA | 70°C/W - thermal performance validated for TSSOP-48 package under standard JEDEC conditions |
| Operating Temp | −40°C to 125°C - qualified per AEC-Q100 for under-hood automotive applications |
| Bus-Hold Current | ±750 µA max - ensures robust input state retention without external biasing components |

| 1A1–1A8, 2A1–2A8 | Port A data inputs/outputs | Connect to local 3.3-V domain; bus-hold active when undriven |
| 1B1–1B8, 2B1–2B8 | Port B data inputs/outputs | 5-V tolerant I/O; interfaces directly with legacy 5-V subsystems |
| VCC (Pins 7, 18, 29, 40) | Supply voltage | Distributed power pins minimize ground bounce and supply noise in high-speed switching |
| GND (Pins 4, 11, 22, 33, 44) | Ground reference | Five GND pins provide low-inductance return path and reduce simultaneous switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode signal operation | 3.3-V VCC with 5-V tolerant I/O eliminates external level translators in hybrid voltage systems |
| Ioff and power-up 3-state | Prevents backflow current and driver conflicts during hot insertion or power sequencing |
| Bus-hold on all data inputs | Removes need for external pullup/pulldown resistors, reducing BOM count and PCB area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVTH16245A | Commercial-grade (−40°C to 85°C), same pinout and electrical specs but lacks AEC-Q100 qualification | Not suitable for under-hood or safety-critical automotive use; limited temperature range | Select only for non-automotive industrial or test equipment where extended temperature is not required |
| CLVTH16245AQDLRQ1 | Same automotive qualification, but SSOP-48 package (DL) with larger footprint and higher θJA (63°C/W) | Less suitable for space-constrained layouts; requires different PCB land pattern and stencil design | Choose when thermal margin is prioritized over board area, or when SSOP is already standardized in existing design |
Compared with CLVTH16245AQDGGRQ1, SN74LVTH16245A lacks automotive qualification and thermal robustness, while CLVTH16245AQDLRQ1 trades compact TSSOP size for improved thermal dissipation in SSOP-making CLVTH16245AQDGGRQ1 optimal for space-constrained, high-reliability automotive modules requiring both miniaturization and AEC-Q100 compliance.

FAQ
What is the maximum operating temperature range for CLVTH16245AQDGGRQ1?
The CLVTH16245AQDGGRQ1 is rated for continuous operation from −40°C to +125°C and is AEC-Q100 qualified for automotive under-hood applications. This full industrial temperature range is guaranteed across all electrical parameters in the datasheet, including propagation delay, drive strength, and bus-hold functionality-ensuring reliability in extreme thermal environments encountered in modern powertrain and chassis control systems.
Does CLVTH16245AQDGGRQ1 support hot insertion, and how is it implemented?
Yes, CLVTH16245AQDGGRQ1 supports hot insertion through two integrated features: Ioff circuitry disables outputs when VCC = 0 V to prevent damaging current backflow, and power-up 3-state holds outputs in high-impedance until VCC stabilizes above 1.5 V. These functions are inherent to the silicon design and require no external components-enabling safe live replacement of modules in running vehicle networks such as body control or ADAS domains.
Can CLVTH16245AQDGGRQ1 interface between 3.3-V and 5-V logic without external level shifters?
Yes, CLVTH16245AQDGGRQ1 natively supports mixed-mode operation: its VCC is 2.7–3.6 V, yet all inputs and outputs tolerate up to 5.5 V. This allows direct connection of 3.3-V microcontrollers to legacy 5-V peripherals-such as sensors, displays, or actuators-without discrete level shifters or resistive dividers, preserving signal integrity and reducing bill-of-materials cost in automotive subsystems.
What is the purpose of bus-hold circuitry in CLVTH16245AQDGGRQ1, and how does it affect system design?
The bus-hold circuitry in CLVTH16245AQDGGRQ1 actively maintains the last-valid logic state on undriven or floating data inputs using ±750 µA dynamic hold current. This eliminates the need for external pullup/pulldown resistors, reducing PCB space, BOM count, and potential signal degradation-particularly valuable in automotive modules where connector open-circuits or intermittent wiring faults must not cause undefined logic states in safety-critical data paths.
How does the flow-through architecture of CLVTH16245AQDGGRQ1 improve PCB layout?
The flow-through architecture positions A-side pins (1A1–1A8, 2A1–2A8) on one half of the TSSOP-48 package and B-side pins (1B1–1B8, 2B1–2B8) on the opposite half, with DIR/OE and power pins distributed across edges. This enables straight-through trace routing-minimizing layer count, vias, and crosstalk-critical for meeting automotive EMI requirements and simplifying layout in dense ECU and ADAS PCBs where signal integrity and thermal management are tightly coupled.
