Product details
Overview
74HC27BQ-Q100 from Nexperia is an automotive-qualified triple 3-input NOR gate in DHVQFN14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 8 ns at VCC = 6.0 V and guaranteed operation from –40 °C to +125 °C. It features CMOS-level inputs, clamp diodes enabling overvoltage-tolerant interfacing, and AEC-Q100 Grade 1 qualification for engine control and body electronics.
For engineers reviewing the 74HC27BQ-Q100 datasheet, 74HC27BQ-Q100 pinout, 74HC27BQ-Q100 application, or 74HC27BQ-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS), thermal-enhanced DHVQFN packaging, automotive temperature range compliance, and NOR logic timing performance under 15 pF load.
Technical Context
This device implements three independent 3-input NOR gates in a single monolithic CMOS structure, with input clamp diodes allowing safe interface to signals exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output drive capability up to ±4.0 mA at VCC = 4.5 V.
Logic behavior follows standard NOR truth table: output is HIGH only when all three inputs are LOW; otherwise output is LOW. Input thresholds scale with VCC for 74HC variant (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), ensuring robust noise immunity across the full 2.0–6.0 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input NOR gate - enables compact implementation of OR-invert logic in control signal conditioning and safety interlocks. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct integration with 3.3 V and 5 V automotive subsystems without level-shifting. |
| Propagation Delay (tpd) | 8 ns (typ) at VCC = 6.0 V, CL = 15 pF - ensures sub-10 ns timing for real-time fault detection circuits. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and transmission control module use. |
| Input Clamp Diodes | Integrated - permits safe connection of inputs to voltages > VCC using external current-limiting resistors. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive ESD robustness requirements for assembly and field operation. |
| Power Dissipation | CPD = 24 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting. |
Pinout & Package
DHVQFN14 package (SOT762-1), 2.5 mm × 3.0 mm × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection, thermally enhanced for high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1, 2, 3) | First input of each NOR gate; accepts CMOS-level signals; clamped to protect against overvoltage. |
| 1B, 2B, 3B | Data input (Gate 1, 2, 3) | Second input of each NOR gate; electrically identical to A inputs; shares same VIH/VIL thresholds. |
| 1C, 2C, 3C | Data input (Gate 1, 2, 3) | Third input of each NOR gate; completes 3-input NOR function; fully rail-to-rail compatible. |
| 1Y, 2Y, 3Y | Data output (Gate 1, 2, 3) | Active-low NOR output; drives loads up to ±4.0 mA; VOH ≥ 4.4 V and VOL ≤ 0.26 V at VCC = 4.5 V. |
| GND (Pin 7) | Ground reference | 0 V reference for all I/O and supply; must be low-impedance for noise immunity and timing stability. |
| VCC (Pin 14) | Positive supply | Primary power rail; decoupling capacitor required near pin for transient current handling during switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient, including accelerated lifetime and stress testing per JEDEC standards. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated QFN packages, improving manufacturing yield in SMT lines. |
| Input clamp diodes | Allows safe interface to external signals up to VCC + 0.5 V using series resistors - eliminates need for external protection diodes. |
| Low dynamic power | CPD = 24 pF enables <1 μW/MHz dynamic power at 3.3 V - critical for always-on vehicle modules with strict quiescent current limits. |
| High noise immunity | Typical noise margin > 1.5 V at VCC = 4.5 V due to wide VIH–VIL separation - suppresses false triggering in electrically noisy engine bays. |
Applications
| Engine Control Unit (ECU) Safety Interlock | Body Control Module (BCM) Door Lock Logic |
|---|---|
|
Use Scenario: Monitoring three independent crankshaft position sensor outputs to validate synchronized rotation before enabling fuel injection. IC Role / Device Role / Timing Role: Triple NOR gate performs real-time logical OR-invert of sensor fault flags - asserts active-HIGH "safe-to-start" signal only when all sensors report valid status. Use Value: Sub-10 ns propagation delay ensures fault detection occurs within one microcontroller instruction cycle, meeting ISO 26262 ASIL-B timing constraints. |
Use Scenario: Combining door ajar, lock actuator feedback, and ignition status to enable/disable central locking actuation. IC Role / Device Role / Timing Role: Implements combinatorial logic for lock/unlock permission - each NOR gate processes one door's state vector before feeding into master control logic. Use Value: CMOS-level compatibility allows direct connection to 3.3 V microcontroller GPIOs and 12 V relay drivers via simple resistor networks. |
| Transmission Control Module (TCM) Gear Selector Validation | Advanced Driver Assistance System (ADAS) Camera Power Sequencing |
|
Use Scenario: Validating simultaneous engagement of P/R/N/D signals from mechanical gear selector switch matrix. IC Role / Device Role / Timing Role: Detects invalid combinations (e.g., P+R asserted together) by NOR-ing complementary switch pairs - triggers immediate neutral-safety shutdown. Use Value: AEC-Q100 qualification and –40 °C to +125 °C operation ensure reliability in high-temperature transmission oil environments. |
Use Scenario: Coordinating power-up sequence between image sensor, ISP, and serializer ICs in rear-view camera modules. IC Role / Device Role / Timing Role: Generates synchronized enable pulses using inverted logic states from system controller - prevents bus contention during initialization. Use Value: Low 24 pF CPD minimizes dynamic current draw during frequent power-cycle events, extending module standby battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT27BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min), fixed 4.5–5.5 V supply range - no 2.0–3.6 V operation. | Better suited for legacy 5 V systems with mixed TTL/CMOS logic; less flexible for multi-rail designs. | Select when interfacing directly with 5 V TTL outputs and supply is strictly 5 V. |
| SN74LVC1G02DPWR | Single 2-input NOR in X2SON-6 package; 1.65–5.5 V supply; higher speed (4.5 ns typ) but not functionally equivalent. | Requires three devices plus external wiring to replicate triple 3-input functionality - increases board area and routing complexity. | Choose only for space-constrained, low-channel-count applications where gate count can be re-architected. |
Compared with 74HC27BQ-Q100, the 74HCT27BQ-Q100 trades supply flexibility for TTL input compatibility, while the SN74LVC1G02DPWR sacrifices integration density and functional equivalence for raw speed and ultra-small footprint - neither offers drop-in replacement capability without circuit redesign.

FAQ
What is the maximum recommended supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per datasheet Table 5. Operation above 6.0 V risks exceeding internal oxide breakdown limits and voids AEC-Q100 qualification guarantees, even if clamping diodes remain functional.
Can 74HC27BQ-Q100 interface directly with 5 V TTL outputs?
No - its CMOS inputs require VIH ≥ 0.7×VCC, so at VCC = 5 V, minimum HIGH input is 3.5 V. Standard TTL outputs (VOH ≈ 2.4–2.7 V) fall below this threshold. Use 74HCT27BQ-Q100 instead, which specifies VIH = 2.0 V min for 5 V operation.
Is the exposed thermal pad (Pin 1 index area) required to be soldered to ground?
No - per datasheet Section 5.1, the thermal pad has no electrical or mechanical requirement to be soldered. If connected, it must remain floating or tied to GND; intentional grounding improves thermal resistance by ~15 °C/W but is optional for functional operation.
How does the DHVQFN14 package improve manufacturability versus SO14 or TSSOP14?
The DHVQFN14's side-wettable flanks allow automated optical inspection (AOI) of solder fillets - unlike SO14 and TSSOP14, which require X-ray or ICT for hidden-joint verification. This reduces final-test escapes and improves first-pass yield in high-volume automotive SMT lines.
