Product details
Overview
74HC27D-Q100 from Nexperia is an automotive-qualified triple 3-input NOR gate in SO14 (SOT108-1) 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, body electronics, and ADAS sensor logic.
For engineers reviewing the 74HC27D-Q100 datasheet, 74HC27D-Q100 pinout, 74HC27D-Q100 application, or 74HC27D-Q100 equivalent, key selection criteria include supply voltage range (2.0–6.0 V), temperature grade (−40 °C to +125 °C), input compatibility (CMOS), output drive strength (±4.0 mA at VCC = 4.5 V), and automotive qualification status per AEC-Q100.
Technical Context
This device implements three independent 3-input NOR logic functions in a single monolithic CMOS IC. Each gate follows the Boolean expression Y = NOT(A + B + C), with inputs protected by integrated clamp diodes that allow safe interfacing to signals exceeding VCC when used with current-limiting resistors.
It complies with JEDEC standards JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), supports TTL-level compatible variants (74HCT27D-Q100), and delivers high noise immunity (>50% of VCC) alongside latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input NOR gate; each output asserts LOW only when all three inputs are HIGH. |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V systems without level translation. |
| Propagation Delay | 8 ns (typ) at VCC = 6.0 V - ensures timing-critical combinational logic paths meet sub-10 ns budgets. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC inputs or small capacitive loads (<15 pF). |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive environments including powertrain and chassis modules. |
| Input Compatibility | CMOS-level inputs - VIH = 3.15 V (min) at VCC = 4.5 V; eliminates need for external pull-ups in high-impedance interfaces. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and assembly in automotive production lines. |
Pinout & Package
74HC27D-Q100 uses the SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, with gull-wing leads and standard pin 1 index marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (Gate 1–3 A) | Three independent input pins per NOR gate; accept CMOS-level signals; include internal clamp diodes. |
| 1B, 2B, 3B | Data input (Gate 1–3 B) | Second input per gate; electrically identical to A/C inputs; supports wired-OR expansion via external diodes. |
| 1C, 2C, 3C | Data input (Gate 1–3 C) | Third input per gate; fully buffered; no internal series resistance - preserves signal edge integrity. |
| 1Y, 2Y, 3Y | Data output (Gate 1–3 Y) | Active-low NOR outputs; rail-to-rail swing; specified VOH ≥ 3.98 V and VOL ≤ 0.26 V at 4.0 mA load. |
| GND (Pin 7) | Ground reference | Primary 0 V return path; must be low-inductance connection to minimize ground bounce in multi-gate switching. |
| VCC (Pin 14) | Positive supply | Single supply input; decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including thermal cycling, HTOL, and ESD stress testing. |
| Integrated input clamp diodes | Enables robust interfacing to voltages up to VCC + 0.5 V using simple series resistors - eliminates external protection components. |
| Low dynamic power dissipation | CPD = 24 pF - limits switching power to <1.5 mW per gate at 1 MHz and 5 V, reducing thermal load in dense PCB layouts. |
| High noise immunity | Typical noise margin >1.3 V at VCC = 4.5 V - prevents false triggering in electrically noisy engine bay or motor drive environments. |
| JEDEC-compliant I/O levels | Fully compatible with JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) - ensures interoperability with legacy and modern logic families. |
Applications
| Engine Control Unit (ECU) Safety Logic | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Detecting simultaneous fault conditions (e.g., overtemperature + overcurrent + invalid enable) before disabling a high-side driver. IC Role / Device Role / Timing Role: Combinational safety interlock - performs real-time 3-input NOR on asynchronous sensor flags to generate immediate hardware shutdown signal. Use Value: Sub-10 ns response time ensures fault reaction occurs within one MCU instruction cycle, meeting ASIL-B timing constraints. |
Use Scenario: Consolidating door lock, window lift, and mirror fold control signals into a single enable bus for power distribution ICs. IC Role / Device Role / Timing Role: Signal combiner - aggregates three independent control inputs to assert a shared "system active" flag with deterministic propagation. Use Value: Eliminates need for microcontroller GPIO polling; reduces firmware latency and frees CPU cycles for higher-priority tasks. |
| ADAS Camera Power Sequencing | Electric Power Steering (EPS) Diagnostic Interface |
Use Scenario: Validating camera sensor readiness (I²C ACK + PWDN deasserted + RESET released) before enabling image processor clock. IC Role / Device Role / Timing Role: Hardware-ready arbiter - NOR output goes HIGH only when all three prerequisites are met, gating clock enable to downstream logic. Use Value: Prevents race conditions during cold boot; ensures pixel data validity before first frame capture, avoiding corrupted initialization. |
Use Scenario: Generating diagnostic inhibit signal when EPS motor current exceeds threshold, torque sensor fails, and CAN error counter exceeds limit. IC Role / Device Role / Timing Role: Fault aggregation node - combines three independent analog/digital fault indicators into a single hardware interrupt source for MCU. Use Value: Enables deterministic, zero-software-latency fault escalation - critical for ISO 26262 ASIL-C diagnostic coverage requirements. |
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 |
|---|---|---|---|
| 74HCT27D-Q100 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout, package, and AEC-Q100 Grade 1 rating. | Better suited for mixed-logic systems with legacy 5 V TTL outputs; slightly higher ICC at VCC = 5.5 V. | Select when interfacing directly to 74LS/74F outputs without level shifters. |
| SN74LVC1G10DRYR | Single 3-input NOR in 6-pin X2SON; operates down to 1.65 V; not AEC-Q100 qualified. | Limited to non-safety-critical consumer or industrial applications; requires three devices for functional equivalence. | Choose only for space-constrained, non-automotive designs where qualification is unnecessary. |
Compared with 74HC27D-Q100, the 74HCT27D-Q100 offers seamless TTL interfacing but sacrifices some noise margin, while SN74LVC1G10DRYR trades qualification and integration for ultra-small footprint and lower voltage support - neither matches the original's balance of automotive compliance, triple-gate density, and 2–6 V flexibility.

FAQ
Is 74HC27D-Q100 pin-compatible with non-automotive 74HC27 variants?
Yes - it shares identical pinout, electrical characteristics, and SO14 (SOT108-1) package with standard 74HC27, but adds AEC-Q100 Grade 1 qualification, extended temperature validation (−40 °C to +125 °C), and enhanced ESD robustness (HBM >2000 V). No layout changes are needed for drop-in replacement in automotive redesigns.
Can 74HC27D-Q100 interface directly with 3.3 V microcontrollers?
Yes - its CMOS inputs guarantee VIH ≥ 2.1 V at VCC = 4.5 V and VIH ≥ 1.5 V at VCC = 2.0 V, making it fully compatible with 3.3 V GPIO outputs. With VCC = 3.3 V, VOH remains ≥ 2.9 V and VOL ≤ 0.3 V at 4 mA load, ensuring reliable driving of subsequent 74HC inputs.
What is the maximum capacitive load this device can drive reliably?
At VCC = 4.5 V and Tamb = 25 °C, 74HC27D-Q100 maintains tPLH/tPHL ≤ 23 ns with CL = 15 pF (per Table 7). For reliable operation beyond 15 pF, derate propagation delay linearly: +1 ns per additional 2 pF up to 50 pF, verified in Nexperia's test circuit (Fig. 5, RL = 1 kΩ).
Does the SO14 package support automated optical inspection (AOI)?
No - unlike the DHVQFN14 (SOT762-1) variant, the SO14 (SOT108-1) package lacks side-wettable flanks and is not AOI-optimized. For AOI-capable alternatives, consider 74HC27BQ-Q100 in DHVQFN14, which enables solder-joint verification in high-reliability automotive SMT lines.
