Product details
Overview
HEF40175BTT-Q100 from Nexperia is a quad positive-edge-triggered D-type flip-flop with asynchronous master reset, four independent D inputs (D0–D3), common clock (CP), and complementary buffered Q/Q̅ outputs per stage. It operates across 3.0 V to 15.0 V supply, supports automotive-grade temperature range (−40 °C to +125 °C), and delivers propagation delays as low as 17 ns at 15 V with 50 pF load - used in synchronous data latching and state-holding within automotive control modules.
For engineers reviewing the HEF40175BTT-Q100 datasheet, HEF40175BTT-Q100 pinout, HEF40175BTT-Q100 application, or HEF40175BTT-Q100 equivalent, key selection criteria include edge-triggered timing integrity, AEC-Q100 Grade 1 qualification, wide-VDD static operation, and dual-rail output drive capability for noise-immune digital interfacing.
Technical Context
This device implements four independent CMOS D-type flip-flops sharing one clock and one active-low master reset line. Each stage latches D-input data on the LOW-to-HIGH transition of CP while maintaining full static operation - no minimum clock frequency required. The MR input forces all Q outputs LOW and Q̅ HIGH regardless of clock or data state.
Input clamp diodes enable safe interfacing to voltages exceeding VDD when used with current-limiting resistors. Output drive strength is specified across 5 V/10 V/15 V rails, with VOH ≥ 14.95 V and VOL ≤ 0.05 V at 15 V, supporting robust fan-out in mixed-voltage automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - enables direct interface with legacy 5 V, modern 12 V automotive domains, and high-voltage sensor signal conditioning stages. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood engine control, transmission, and ADAS ECU applications. |
| Propagation Delay (tPHL/tPLH) | 17 ns to 50 ns at 15 V (CL = 50 pF) - ensures sub-50 ns setup/hold timing margins for 10 MHz+ synchronous logic in real-time control loops. |
| Output Drive Strength | IOH = −2.4 mA / IOL = 2.4 mA at 15 V - sufficient to drive multiple 74HC inputs or small capacitive loads without external buffers. |
| Input Thresholds (VIH/VIL) | VIH = 11.0 V, VIL = 4.0 V at 15 V - provides >3 V noise margin against transients in noisy automotive power environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive board-level ESD immunity requirements without additional protection circuitry. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1); 16-pin, 4.4 mm body width, 0.65 mm pitch; suitable for automated SMT assembly and high-density PCB layouts in automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Master Reset input | Active-LOW asynchronous reset - forces all Q outputs LOW and Q̅ HIGH independently of clock or data, critical for fail-safe initialization. |
| 2 (Q0), 7 (Q1), 10 (Q2), 15 (Q3) | True output | Buffered, rail-to-rail CMOS outputs - drive downstream logic or LEDs directly; fan-out ≥ 10 LS-TTL loads at 5 V. |
| 3 (Q̅0), 6 (Q̅1), 11 (Q̅2), 14 (Q̅3) | Complementary output | Simultaneous inverted output per stage - eliminates need for external inverters in toggle or differential signaling paths. |
| 4 (D0), 5 (D1), 12 (D2), 13 (D3) | Data input | CMOS-compatible inputs with clamp diodes - tolerate overvoltage up to VDD + 0.5 V when series-resistor limited. |
| 8 (VSS), 16 (VDD) | Power supply | Dual-supply pins support clean decoupling; VSS must be connected before VDD during power sequencing to prevent latch-up. |
| 9 (CP) | Clock input | Edge-triggered on LOW-to-HIGH transition only - immune to glitches on falling edge; set-up/hold times defined down to 5 ns at 15 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including thermal cycling, humidity, and mechanical shock testing. |
| Wide VDD range (3–15 V) | Eliminates level-shifting in multi-rail systems - interfaces natively with 5 V microcontrollers, 12 V sensors, and 15 V actuator drivers. |
| Fully static operation | No minimum clock frequency required - supports ultra-low-power sleep modes where clock may halt indefinitely without data loss. |
| Standardized symmetrical output drive | Matched rise/fall times (6–40 ns) and equal sourcing/sinking capability - reduces skew in parallel data paths and timing-critical registers. |
| Input clamp diodes | Enables safe connection to signals exceeding VDD (e.g., 12 V CAN transceiver outputs) using simple series resistors - no external protection needed. |
Applications
| Shift Registers | Buffer/Storage Register |
|---|---|
|
Use Scenario: Serial-to-parallel conversion in automotive lighting control modules, where PWM commands are shifted in via SPI and latched simultaneously to drive LED strings. IC Role / Device Role / Timing Role: Quad D-flip-flop acts as a 4-bit parallel latch synchronized to system clock edges, holding stable output states between shift cycles. Use Value: Eliminates metastability risk during clock-domain crossing by enforcing strict setup/hold timing and providing glitch-free Q/Q̅ outputs. |
Use Scenario: Input buffering for analog-to-digital converter (ADC) result registers in engine control units, where sampled values must be held stable during CPU read access. IC Role / Device Role / Timing Role: Provides edge-triggered storage of 4-bit status flags (e.g., knock detection, misfire, O2 heater fault) with simultaneous readout capability. Use Value: Complementary outputs allow direct connection to both active-HIGH and active-LOW interrupt lines without external inverters. |
| Pattern Generator | State Machine Sequencer |
|
Use Scenario: Generating fixed timing sequences for fuel injector driver activation in sequential port injection systems, cycling through 4-phase firing order. IC Role / Device Role / Timing Role: Configured as a 4-bit ring counter using feedback from Q3 to D0 and MR for reset synchronization to crankshaft position sensor edges. Use Value: Propagation delay consistency (< ±5 ns variation across voltage/temp) ensures deterministic phase alignment across cylinders. |
Use Scenario: Implementing finite-state logic for HVAC blend door actuator control, where each flip-flop represents a motor direction or limit switch status bit. IC Role / Device Role / Timing Role: Stores current state bits (e.g., OPEN/CLOSE/STOP) and updates synchronously on CP edge, with MR enabling hard reset on power-up or fault condition. Use Value: Asynchronous MR guarantees known initial state regardless of clock stability during cold start - critical for safety-critical motion control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV175APWR | Lower VDD range (2–5.5 V); faster tpd (5.5 ns @ 3.3 V); no AEC-Q100 qualification; LVTTL-compatible thresholds. | Limited to 5 V automotive infotainment or body electronics; unsuitable for 12 V powertrain domains requiring extended voltage range. | Select when operating exclusively at 3.3 V/5 V with speed priority and non-safety-critical placement. |
| MC74HC175ADTR2G | Wider temp range (−55 °C to +125 °C); identical pinout; AEC-Q100 Grade 2 (−40 °C to +105 °C); slightly higher ICC at 15 V. | Acceptable for under-dash modules but not under-hood due to lower max ambient rating; requires external ESD protection beyond HBM 2 kV. | Choose for cost-sensitive designs where Grade 2 qualification suffices and 15 V operation is not required. |
Compared with SN74LV175APWR and MC74HC175ADTR2G, the HEF40175BTT-Q100 uniquely combines 15 V tolerance, AEC-Q100 Grade 1 qualification, and integrated input clamping - making it the only option qualified for direct integration into 12 V/15 V powertrain control units without external protection or level-shifting.

FAQ
What is the maximum clock frequency supported by HEF40175BTT-Q100?
The device supports up to 45 MHz maximum clock frequency at 15 V supply with 50 pF load, as specified in the dynamic characteristics table. At 5 V, fmax drops to 11 MHz due to slower switching; actual usable frequency depends on load capacitance and board layout parasitics - design margin should include ≥20% derating for automotive EMI environments.
Can HEF40175BTT-Q100 operate with mixed voltage inputs (e.g., 12 V signals into a 5 V VDD system)?
Yes - input clamp diodes allow safe interface to voltages up to VDD + 0.5 V. For 12 V signals into a 5 V system, a series current-limiting resistor (≥10 kΩ) is required to restrict IIK to <±10 mA per input, preventing damage while preserving logic thresholds. This is validated per JEDEC JS-001 and documented in Section 6.2.
Is the master reset (MR) pin synchronous or asynchronous?
MR is fully asynchronous and active-LOW: asserting MR immediately forces all Q outputs LOW and Q̅ outputs HIGH, independent of clock state or timing. Recovery time after MR release is specified as 0 ns to 15 ns (negative values indicate setup margin), ensuring deterministic reset behavior even during clock instability or power brownouts.
Does HEF40175BTT-Q100 require external pull-up or pull-down resistors on unused inputs?
No - all inputs have internal clamp diodes and CMOS structure with negligible leakage (<±0.1 μA at 15 V). Unused inputs may be tied directly to VDD or VSS without external resistors. However, for best noise immunity in automotive harness environments, tying unused D inputs to VSS is recommended to prevent floating node coupling.
