Texas Instruments CLVC2G101WBQBRQ1

Overview

CLVC2G101WBQBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive dual D-type flip-flop with configurable multi-function gated clock logic, operating from 1.1V to 3.6V supply, supporting 5.5V over-voltage tolerant inputs, and delivering ±24mA output drive at 3.3V. It enables momentary-to-toggle switch conversion and clock division by 2 or 4 in body control modules and ADAS sensor interfaces.

For engineers reviewing the CLVC2G101WBQBRQ1 datasheet, CLVC2G101WBQBRQ1 pinout, CLVC2G101WBQBRQ1 application, or CLVC2G101WBQBRQ1 equivalent, key selection factors include its Schmitt-trigger input hysteresis (ΔVT ≥ 0.07V), 7ns max propagation delay at 3.3V, Ioff partial-power-down support, and dual-channel independent clear (CLR) and data (D) paths with four programmable clock inputs per channel.

Technical Context

The CLVC2G101WBQBRQ1 implements two independent D-type flip-flops, each with asynchronous active-low CLR and four configurable clock inputs (CLKA–CLKD) that feed combinational logic to generate a single internal clock (Y) - enabling AND, OR, NAND, NOR, XOR, XNOR, or inverted/non-inverted 1-input operation. All inputs feature Schmitt-trigger architecture for noise immunity.

Its functional mode relies on synchronous edge-triggered data capture on Y↑ (derived from CLKx combinations) and asynchronous reset via CLR↓. The device supports partial power-down (Ioff) with back-drive protection and operates across –40°C to +125°C ambient, meeting AEC-Q100-002 HBM (±2000V) and AEC-Q100-011 CDM (±1000V) ESD requirements.

Key Specifications

Pinout & Package

FAQ

What is the maximum clock frequency supported by CLVC2G101WBQBRQ1?

The CLVC2G101WBQBRQ1 supports up to 160MHz clock frequency at 3.3V ±0.3V supply, as specified in the Timing Characteristics table. At lower voltages, maximum frequency decreases: 150MHz at 2.5V, 70MHz at 1.8V, and 40MHz at 1.5V. These values assume proper load capacitance (≤50pF) and signal integrity; actual system-level timing must account for board trace delays and input transition rates.

Does CLVC2G101WBQBRQ1 require external pull-up or pull-down resistors on unused clock inputs?

No - CLVC2G101WBQBRQ1 does not require external resistors on unused clock inputs because all inputs feature Schmitt-trigger architecture with defined hysteresis. However, TI recommends terminating unused inputs to VCC or GND to prevent floating states that could increase dynamic current consumption. A 10kΩ resistor is typical if the input may be repurposed later.

Can CLVC2G101WBQBRQ1 operate with a 5V input signal while powered from a 1.8V supply?

Yes - CLVC2G101WBQBRQ1 supports over-voltage tolerant inputs up to 5.5V independent of VCC. When powered from 1.8V, it safely accepts 5V signals on CLKA–CLKD, D, and CLR pins without damage or level-shifting circuitry, making it ideal for interfacing legacy 5V sensors or switches in modern low-voltage automotive systems.

How does the configurable clock logic in CLVC2G101WBQBRQ1 work?

The CLVC2G101WBQBRQ1 uses four clock inputs (CLKA–CLKD) per channel feeding combinational logic that generates a single internal clock (Y). By tying specific inputs high or low, users configure Y as AND, OR, NAND, NOR, XOR, XNOR, or inverted/non-inverted 1-input functions - enabling hardware-based clock gating, edge detection, or logic synthesis without external gates or FPGA resources.

Is CLVC2G101WBQBRQ1 pin-compatible with other TI dual flip-flop devices?

No - CLVC2G101WBQBRQ1 uses a unique 16-pin WQFN (BQB) package with dedicated CLKA–CLKD inputs per channel, differing from standard 8-pin or 14-pin dual DFF packages like SN74LVC2G74 or SN74LVC2G175. Its pinout is specific to its configurable clock architecture and is not pin-compatible with any other TI dual flip-flop device.
