Product details
Overview
CLVC16244AIDGGRQ1 from Texas Instruments is an automotive-qualified 16-bit noninverting buffer/driver with 3-state outputs, operating from 1.65 V to 3.6 V, supporting mixed-mode 5-V input/3.3-V VCC operation, with 4.1 ns max propagation delay at 3.3 V and Ioff partial-power-down protection. It serves as a high-density bus driver in automotive infotainment backplanes and ADAS sensor interface modules.
For engineers reviewing the CLVC16244AIDGGRQ1 datasheet, CLVC16244AIDGGRQ1 pinout, CLVC16244AIDGGRQ1 application, or CLVC16244AIDGGRQ1 equivalent, key selection considerations include AEC-Q100 qualification, 48-pin TSSOP (DGG) package compatibility, true 3-state output control per 4-bit group, and robust 5.5-V-tolerant inputs in automotive power domain isolation scenarios.
Technical Context
This device implements four independent 4-bit noninverting buffers, each with dedicated active-low 3-state enable (1OE–4OE), enabling flexible partitioning as one 16-bit, two 8-bit, or four 4-bit drivers. All inputs tolerate up to 5.5 V regardless of VCC level, enabling direct interfacing between legacy 5-V logic and modern 3.3-V domains.
The Ioff circuitry actively disables outputs during power-down, blocking current backflow when VCC = 0 V, and latch-up performance exceeds 100 mA per JESD 17. Output drive strength is ±24 mA at 3.0 V, with VOH ≥ 2.2 V and VOL ≤ 0.55 V under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 3.6 V - Enables use across low-voltage automotive subsystems including body control and telematics. |
| Max Propagation Delay | 4.1 ns at VCC = 3.3 V - Supports high-speed address/data buffering in CAN FD gateway timing-critical paths. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct connection to 5-V microcontrollers or sensors without level-shifting circuitry. |
| Ioff Current | ±10 µA at VI/VO = 5.5 V - Prevents damaging back-current during hot-swap or partial-power-down sequences. |
| Output Drive | ±24 mA at VCC = 3.0 V - Sustains signal integrity driving 50-Ω transmission lines or multiple CMOS loads in ECU bus interfaces. |
| Operating Temperature | –40°C to +85°C - Qualified for under-hood and cabin-mounted automotive electronics per AEC-Q100 Grade 2. |
| ESD Protection | 2000-V HBM, 1000-V CDM - Meets stringent automotive board-level ESD immunity requirements. |
Pinout & Package
CLVC16244AIDGGRQ1 uses a 48-pin TSSOP package (DGG), 12.6 mm × 6.2 mm × 1.2 mm max height, with 0.5-mm pitch, JEDEC MO-153 compliant, moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE–4OE | Active-low output enable | Independent control per 4-bit group; tie high via pullup to ensure Hi-Z during power-up. |
| 1A1–4A4 | Buffer inputs | 16 total inputs tolerant to 5.5 V; accept 3.3-V or 5-V logic levels regardless of VCC. |
| 1Y1–4Y4 | True buffered outputs | 16 noninverting outputs with 3-state capability; drive buses or distributed loads with controlled edge rates. |
| VCC (Pins 7, 18, 29, 40) | Supply voltage | Four dedicated VCC pins reduce IR drop and improve noise immunity across wide bus traces. |
| GND (Pins 4, 10, 15, 22, 27, 32, 37, 43) | Ground reference | Eight GND pins provide low-inductance return paths essential for clean switching in high-speed automotive buses. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Qualified for automotive applications (Grade 2); includes enhanced DMS support and change notification. |
| Mixed-Mode Signal Operation | 5-V-tolerant inputs with 3.3-V VCC enable seamless integration into hybrid-voltage vehicle networks. |
| Ioff Partial-Power-Down | Outputs automatically enter high-impedance state when VCC = 0 V, preventing backfeed in multi-rail systems. |
| Low Ground Bounce | Typical VOLP < 0.8 V at VCC = 3.3 V ensures stable logic thresholds during simultaneous switching. |
| Widebus™ Architecture | Optimized pinout and layout for minimal crosstalk and skew in parallel bus implementations. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16244AQDRQ1 | Same electrical specs and AEC-Q100 qualification; differs only in SOIC (DW) package (56-pin) and tape-and-reel quantity (2500 pcs). | SOIC package offers higher thermal mass and easier manual rework but requires ~30% more PCB area than TSSOP. | Select when board space permits and hand-soldering or thermal cycling robustness is prioritized over density. |
| SN74LVCH16244AQGRQ1 | Includes bus-hold circuitry on all inputs; otherwise identical VCC range, drive strength, and timing. | Bus-hold eliminates need for external pullups on unused inputs-critical in modular ECU designs with configurable I/O. | Select when input floating risk exists due to connector disconnection or hot-plug scenarios in field-upgradable modules. |
Compared with SN74LVC16244AQDRQ1, CLVC16244AIDGGRQ1 saves board area in space-constrained modules; versus SN74LVCH16244AQGRQ1, it requires external pullups on unused inputs but reduces input leakage and simplifies biasing in fixed-function designs.

FAQ
What is the maximum operating temperature range for CLVC16244AIDGGRQ1?
The CLVC16244AIDGGRQ1 is rated for operation from –40°C to +85°C ambient temperature, fully qualified per AEC-Q100 Grade 2 for automotive under-hood and cabin applications. This range is validated across all electrical parameters including propagation delay, output drive, and Ioff behavior, ensuring consistent performance in thermal cycling environments typical of engine control units and infotainment head units.
Does CLVC16244AIDGGRQ1 support 5-V input signals while powered at 3.3 V?
Yes, CLVC16244AIDGGRQ1 supports input voltages up to 5.5 V regardless of VCC level (1.65 V to 3.6 V), enabling direct interfacing with legacy 5-V logic without external level shifters. This mixed-mode capability is confirmed in the absolute maximum ratings and recommended operating conditions tables of the SCES631 datasheet, and applies to all 16 inputs (1A1–4A4) of the CLVC16244AIDGGRQ1.
How many independent output-enable controls does CLVC16244AIDGGRQ1 have?
The CLVC16244AIDGGRQ1 features four independent active-low output-enable inputs: 1OE, 2OE, 3OE, and 4OE - one for each 4-bit buffer group. This allows granular control over bus segments, such as enabling only the camera interface section while holding the display driver section in high-impedance during power sequencing. Pin locations are confirmed in the DGG top-view diagram on page 1 of the SCES631 datasheet.
What is the typical output ground bounce (VOLP) specification for CLVC16244AIDGGRQ1?
The typical output ground bounce (VOLP) for CLVC16244AIDGGRQ1 is less than 0.8 V at VCC = 3.3 V and TA = 25°C, as specified in the Features section of the SCES631 datasheet. This low VOLP value reflects optimized output stage design that minimizes transient voltage depression on shared ground planes during simultaneous switching - critical for maintaining noise margins in automotive cluster and ADAS subsystems where CLVC16244AIDGGRQ1 is deployed.
Is CLVC16244AIDGGRQ1 pin-compatible with standard SN74LVC16244A catalog parts?
Yes, CLVC16244AIDGGRQ1 is pin-compatible with the commercial-grade SN74LVC16244A in the same TSSOP-48 (DGG) package, sharing identical pinout, electrical characteristics, and functional behavior. The Q1 suffix denotes AEC-Q100 qualification and automotive-specific manufacturing controls, but no physical or logical changes to the CLVC16244AIDGGRQ1 die or footprint - enabling drop-in replacement in existing designs requiring automotive reliability certification.
