Product details
Overview
SN74LVC2G101PWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive dual D-type flip-flop with configurable gated clock logic, operating from 1.1V to 3.6V, supporting over-voltage tolerant inputs up to 5.5V, and delivering ±24mA output drive at 3.3V for robust signal conditioning in vehicle control modules.
For engineers reviewing the SN74LVC2G101PWRQ1 datasheet, SN74LVC2G101PWRQ1 pinout, SN74LVC2G101PWRQ1 application, or SN74LVC2G101PWRQ1 equivalent, key selection criteria 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 multi-input clock configuration capability.
Technical Context
The SN74LVC2G101PWRQ1 implements two independent edge-triggered D-type flip-flops, each with four configurable clock inputs (CLKA–CLKD) that feed combinational logic to generate a single internal clock (Y) - enabling 2-input AND/OR/NAND/NOR/XOR/XNOR or 1-input inverted/non-inverted modes. All inputs feature Schmitt-trigger architecture for noise immunity on slow or noisy signals.
It supports partial-power-down via Ioff protection, allowing safe back-drive during power sequencing, and operates across -40°C to +125°C with HBM ESD rating of ±2000V and CDM rating of ±1000V - meeting stringent automotive reliability requirements without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.1V to 3.6V - enables direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - allows mixed-voltage system interfacing (e.g., 5V sensors into 1.8V MCU) |
| Max Propagation Delay | 7ns at 3.3V - supports high-speed clock division and toggle applications up to 160MHz |
| Output Drive Strength | ±24mA at 3.3V - drives moderate capacitive loads (≤50pF) and multiple CMOS inputs directly |
| Operating Temperature | -40°C to +125°C (Grade 1) - qualified for under-hood and transmission control unit environments |
| ESD Rating | HBM ±2000V, CDM ±1000V - meets AEC-Q100-002 and -011 for automotive production use |
| Ioff Support | Enabled - prevents current backflow during power-down, critical for hot-swap and multi-rail systems |
Pinout & Package
SN74LVC2G101PWRQ1 is packaged in a 16-pin WQFN (BQB) with 3.5mm × 2.5mm body size and thermal pad. The package supports fine-pitch PCB layout and enhanced thermal dissipation when thermal pad is connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLR1, CLR2 | Asynchronous active-low clear | Resets Q1/Q2 independently to logic low regardless of clock state - essential for deterministic power-up initialization |
| CLKA1–CLKD1, CLKA2–CLKD2 | Configurable clock inputs | Four per channel; routed through internal combinational logic to form Y1/Y2 - enables flexible clock gating and logic synthesis without external gates |
| D1, D2 | Data inputs | Edge-sensitive D inputs synchronized to internal clock Y - accepts standard CMOS logic levels with Schmitt-trigger noise rejection |
| Q1, Q2 | Non-inverted outputs | Push-pull CMOS outputs capable of sourcing/sinking up to ±24mA - suitable for driving LEDs, buffers, or downstream logic |
| VCC, GND | Power supply and ground | Single-supply operation; Ioff protection isolates VCC/GND paths during power loss or sequencing mismatches |
Key Features
| Feature | Design Value |
|---|---|
| Configurable multi-input clock logic | Each channel's CLKA–CLKD inputs synthesize 2-input Boolean functions (AND/OR/XOR/etc.) or invert/non-invert - eliminates need for discrete gate ICs in clock path design |
| Schmitt-trigger inputs | Input hysteresis ΔVT ≥ 0.07V minimizes false triggering from slow edges or EMI - critical for switch debouncing and sensor signal conditioning |
| Over-voltage tolerant inputs | Accepts 0–5.5V inputs while powered from 1.1–3.6V - enables direct connection to legacy 5V subsystems without external voltage translators |
| Automotive AEC-Q100 Grade 1 | Qualified for -40°C to +125°C ambient operation with full electrical characterization - certified for safety-critical body electronics and ADAS domain controllers |
| Ioff partial-power-down | Blocks current flow between powered and unpowered sections - ensures system-level robustness during battery disconnect or rail sequencing |
Applications
| Vehicle Door Module Switch Debounce | ADAS Camera Clock Divider |
|---|---|
Use Scenario: Momentary door latch switches generate mechanical bounce; raw signals must be cleaned before feeding microcontroller GPIOs. IC Role / Device Role / Timing Role: SN74LVC2G101PWRQ1 acts as a synchronous toggle latch with Schmitt-trigger inputs, converting noisy switch closures into clean, edge-stable Q outputs. Use Value: Eliminates software debounce overhead and ensures deterministic response within 7ns propagation delay - improves ASIL-B functional safety compliance. | Use Scenario: A 40MHz camera pixel clock must be divided by 2 or 4 to synchronize with image processing pipeline timing budgets. IC Role / Device Role / Timing Role: SN74LVC2G101PWRQ1 configures CLKA/CLKB as NAND gate to generate divide-by-2 clock; second channel divides again for /4 output. Use Value: Achieves jitter-free division using internal edge-triggered flip-flops - avoids PLL phase noise and reduces BOM count vs. dedicated divider ICs. |
| Electric Power Steering (EPS) Fault Latching | Body Control Module (BCM) Signal Multiplexing |
Use Scenario: Two independent motor fault signals (FAULT1, FAULT2) require latching on first rising edge to trigger fail-safe shutdown. IC Role / Device Role / Timing Role: SN74LVC2G101PWRQ1 uses OR-combined clock inputs and asynchronous CLR to capture and hold fault state until reset. Use Value: Provides hardware-level fault persistence independent of MCU firmware - meets ISO 26262 ASIL-C diagnostic coverage requirements. | Use Scenario: Multiple low-speed LIN bus nodes share a single UART interface; signals must be time-multiplexed onto common data lines. IC Role / Device Role / Timing Role: SN74LVC2G101PWRQ1 toggles enable strobes for bidirectional transceivers using gated clock logic and D-flip-flop timing control. Use Value: Enables deterministic half-duplex arbitration without CPU intervention - reduces latency and frees MCU resources for real-time control tasks. |
Equivalent & Alternatives

FAQ
What is the maximum clock frequency supported by SN74LVC2G101PWRQ1?
The SN74LVC2G101PWRQ1 supports up to 160MHz clock frequency at 3.3V ±0.3V, with lower limits at reduced supply voltages: 150MHz at 2.5V, 70MHz at 1.8V, and 40MHz at 1.5V. These values are specified across -40°C to +125°C and assume proper load capacitance (≤50pF) and signal integrity. The actual usable frequency depends on configured clock logic and board-level routing.
Does SN74LVC2G101PWRQ1 support partial power-down mode?
Yes, SN74LVC2G101PWRQ1 supports Ioff partial-power-down functionality. When VCC = 0V, all inputs and outputs are high-impedance and leakage current is limited to ±10µA, preventing current backflow between powered and unpowered sections - a critical feature for automotive multi-rail systems undergoing controlled power sequencing.
How does the configurable clock logic work in SN74LVC2G101PWRQ1?
The SN74LVC2G101PWRQ1 routes each channel's CLKA–CLKD inputs through internal combinational logic to generate a single effective clock (Y). By tying specific inputs to VCC or GND, users configure Y as AND, OR, NAND, NOR, XOR, XNOR, or inverted/non-inverted versions - enabling flexible clock gating and logic synthesis without external components.
Can SN74LVC2G101PWRQ1 interface with 5V logic signals?
Yes, SN74LVC2G101PWRQ1 features over-voltage tolerant inputs rated to 5.5V independent of VCC, allowing direct connection to 5V sensors, switches, or legacy subsystems while operating from 1.1V–3.6V supplies - eliminating level-shifter ICs and reducing BOM cost and board area in mixed-voltage automotive designs.
What packaging options are available for SN74LVC2G101PWRQ1?
SN74LVC2G101PWRQ1 is offered in two automotive-qualified packages: 16-pin WQFN (BQB, 3.5mm × 2.5mm) with exposed thermal pad, and 16-pin TSSOP (PW, 5mm × 6.4mm). The WQFN variant is preferred for space-constrained applications and improved thermal performance; both packages are AEC-Q100 qualified and RoHS compliant.
