Texas Instruments CLVC2G125IDCTRQ1

Overview

CLVC2G125IDCTRQ1 from Texas Instruments is an automotive-qualified dual 3-state bus buffer gate operating from 1.65 V to 5.5 V, featuring ±24-mA output drive at 3.3 V, 4.3 ns max propagation delay, and Ioff support for partial-power-down mode - used in CAN/LIN transceiver interface buffering and automotive body control module data routing.

For engineers reviewing the CLVC2G125IDCTRQ1 datasheet, CLVC2G125IDCTRQ1 pinout, CLVC2G125IDCTRQ1 application, or CLVC2G125IDCTRQ1 equivalent, key selection criteria include 3.3-V/5-V mixed-voltage signal translation, high-impedance state robustness during power sequencing, latch-up immunity (>100 mA), and SSOP-8 package compatibility with space-constrained automotive PCB layouts.

Technical Context

This device implements two independent noninverting buffers, each with active-low 3-state enable (OE) control logic. Output disable occurs when OE is high, placing Y in high-impedance; inputs tolerate up to 5.5 V regardless of VCC level, enabling level-shifting between 1.8-V, 3.3-V, and 5-V domains.

The Ioff circuitry actively disables outputs when VCC = 0 V, preventing backflow current from live buses into a powered-down system - critical for hot-swap and domain-isolation use cases in automotive infotainment and ADAS subsystems.

FAQ

What is the maximum propagation delay of CLVC2G125IDCTRQ1 at 3.3 V?

The maximum propagation delay (tpd) of CLVC2G125IDCTRQ1 is 4.3 ns when operating at VCC = 3.3 V and TA = 25°C, as specified in the Switching Characteristics table of the official TI datasheet SCES559C. This value applies to both A→Y and OE→Y transitions and ensures timing compliance in high-speed digital control paths such as SPI enable gating and LIN header synchronization. CLVC2G125IDCTRQ1 maintains this performance across its full –40°C to +85°C operating range.

Does CLVC2G125IDCTRQ1 support partial-power-down operation?

Yes, CLVC2G125IDCTRQ1 supports partial-power-down operation via its Ioff feature, which disables outputs and limits leakage to ±10 μA when VCC = 0 V. This prevents damaging current backflow from live signal lines into unpowered sections of the system - a critical capability in automotive gateway modules where multiple power domains coexist. The Ioff specification is verified per JEDEC JESD78 and explicitly guaranteed in the Electrical Characteristics table of the CLVC2G125IDCTRQ1 datasheet.

What package type and dimensions does CLVC2G125IDCTRQ1 use?

CLVC2G125IDCTRQ1 uses the SSOP-8 (DCT) package: 3.0 mm × 3.1 mm body size, 1.3 mm maximum height, 0.65 mm lead pitch, and gull-wing surface-mount leads. It is RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH). The package drawing DCT0008A is published by Texas Instruments and confirmed in the PACKAGE OUTLINE documentation for CLVC2G125IDCTRQ1.

Can CLVC2G125IDCTRQ1 interface 5-V signals with a 1.8-V microcontroller?

Yes, CLVC2G125IDCTRQ1 accepts input voltages up to 5.5 V regardless of VCC level - meaning it can safely translate 5-V logic signals down to a 1.8-V domain when VCC = 1.8 V. Its 5-V-tolerant inputs eliminate external level shifters in mixed-supply systems like automotive telematics units. This capability is explicitly tested and guaranteed in the Recommended Operating Conditions table, where VI(max) = 5.5 V applies across the full 1.65–5.5 V VCC range for CLVC2G125IDCTRQ1.

Is CLVC2G125IDCTRQ1 qualified for automotive applications?

Yes, CLVC2G125IDCTRQ1 is AEC-Q100 qualified (Grade 2, –40°C to +105°C ambient), with full automotive reliability testing including HTOL, temperature cycling, and latch-up immunity exceeding 100 mA per JESD 78 Class II. It is explicitly designated as an automotive-grade part in TI's ordering information and product folder, and carries the "-Q1" suffix confirming its qualification status. All electrical and thermal specifications for CLVC2G125IDCTRQ1 are validated under automotive operating conditions.
