Product details
Overview
74HCT32PW-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in TSSOP14 package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, 27 ns max propagation delay at 125 °C, and AEC-Q100 Grade 1 qualification for under-hood control logic and body electronics.
For engineers reviewing the 74HCT32PW-Q100 datasheet, 74HCT32PW-Q100 pinout, 74HCT32PW-Q100 application, or 74HCT32PW-Q100 equivalent, this device supports robust digital signal combining in automotive powertrain modules, infotainment subsystems, lighting controllers, and ADAS sensor interface logic where input level compatibility and thermal stability are critical.
Technical Context
This device implements four independent OR logic functions using CMOS technology with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V microcontrollers and discrete logic without level translation. Each gate drives ±4.0 mA at VOH/VOL specifications across -40 °C to +125 °C.
Input clamp diodes allow safe operation with input voltages exceeding VCC when used with current-limiting resistors. The TSSOP14 package (SOT402-1) features side-wettable flanks for automated optical inspection of solder joints - a key requirement for automotive PCB assembly traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Four independent 2-input OR gates; outputs true when ≥1 input is HIGH. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail with ±10 % tolerance margin. |
| Propagation Delay (tpd) | 36 ns max at VCC = 4.5 V, Tamb = +125 °C - ensures timing predictability in high-temp engine bay environments. |
| Output Drive Strength | ±4.0 mA at VOH ≥ 3.7 V / VOL ≤ 0.4 V - sufficient to drive multiple 74-series inputs or small LED indicators. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - compatible with TTL output levels and avoids marginal switching near 1.5 V. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and chassis-mounted applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive ESD immunity requirements for handling and board-level stress. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, side-wettable flanks for AOI.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 4A, 9A, 12A | Input A of Gates 1–4 | Dedicated first input per OR gate; accepts TTL-level signals up to VCC + 0.5 V with clamping. |
| 2B, 5B, 10B, 13B | Input B of Gates 1–4 | Dedicated second input per OR gate; electrically identical to A inputs; symmetrical VIH/VIL. |
| 3Y, 6Y, 8Y, 11Y | Output Y of Gates 1–4 | CMOS push-pull output; rail-to-rail swing; capable of sourcing/sinking 4 mA while maintaining VOH/VOL specs. |
| 7 | GND | Ground reference (0 V); mandatory connection for logic reference and noise immunity. |
| 14 | VCC | Positive supply input; must be decoupled locally with 100 nF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and HTRB testing. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates need for external level shifters with 5 V MCU I/O. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times (tt ≤ 22 ns) and reduced skew between gates. |
| Input clamp diodes | Enable safe overvoltage tolerance (up to VCC + 0.5 V) when series resistors limit current to < ±20 mA. |
| Side-wettable flanks (TSSOP14) | Facilitates automated optical inspection of solder joint quality on bottom terminals - required for IATF 16949 production lines. |
Applications
| Engine Control Unit (ECU) Diagnostics Logic | Automotive Lighting Control Module |
|---|---|
|
Use Scenario: Combining fault flags from multiple sensors (e.g., camshaft/crankshaft position, knock, coolant temp) into a single "system error" signal routed to dashboard warning cluster. IC Role / Device Role / Timing Role: Digital OR combiner for asynchronous status bits; no clock required; operates at DC to <1 MHz. Use Value: Reduces component count vs. discrete transistor logic; maintains fail-safe behavior (any fault → HIGH output) across full automotive temperature range. |
Use Scenario: Enabling headlight high-beam function only when both low-beam is active AND high-beam switch is asserted - implemented via OR-based enable gating in LED driver subsystem. IC Role / Device Role / Timing Role: Combinational logic element in safety-critical lighting path; meets ISO 26262 ASIL-A functional requirements for deterministic response. Use Value: Guarantees sub-40 ns worst-case propagation at 125 °C, preventing race conditions during rapid beam switching sequences. |
| Body Control Module (BCM) Door Lock Interface | ADAS Camera Power Sequencing Logic |
|
Use Scenario: Merging lock/unlock commands from key fob receiver, door handle sensor, and central console switch into unified actuator enable signal. IC Role / Device Role / Timing Role: Input consolidation node feeding downstream driver IC; operates in always-on domain with 5 V rail. Use Value: Input clamp diodes tolerate transient coupling from adjacent RF receivers; ESD rating prevents latch-up during ESD events near door apertures. |
Use Scenario: Generating "camera ready" signal by OR-ing power-good outputs from three independent LDOs supplying image sensor, ISP, and interface PHY. IC Role / Device Role / Timing Role: Power sequencing monitor; output asserts only after all three supplies stabilize - used as reset release trigger. Use Value: Low ICC (<40 μA at 125 °C) minimizes quiescent load on always-on bias rail; stable VIH/VIL prevents false triggering during supply ramp. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT32D-Q100 | SO14 package (SOT108-1); 3.9 mm body width; no side-wettable flanks. | Lacks AOI support; suitable for manual rework or non-automated SMT lines. | Select when board space allows wider SO package and AOI is not required. |
| 74HCT32BQ-Q100 | DHVQFN14 package (SOT762-1); 2.5 × 3 mm footprint; thermal pad; no leads. | Superior thermal performance (9.6 mW/K derating above 98 °C); requires stencil-defined solder paste volume control. | Select for ultra-compact layouts or high-power-density modules needing enhanced thermal dissipation. |
Compared with 74HCT32PW-Q100, the SO14 variant trades AOI capability for easier hand-soldering and legacy footprint compatibility, while the DHVQFN offers 40 % smaller area and better thermal resistance but demands tighter process control for solder joint reliability.

FAQ
Is 74HCT32PW-Q100 pin-compatible with standard 74HCT32 devices?
Yes - it shares identical pinout (SOT402-1 TSSOP14) and electrical behavior with non-automotive 74HCT32 variants. However, only the -Q100 suffix indicates AEC-Q100 Grade 1 qualification, extended temperature validation, and automotive-specific test reporting. Non-Q100 versions lack these certifications and are not approved for automotive use.
Can 74HCT32PW-Q100 operate at 3.3 V supply?
No - the 74HCT32 variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) become marginal relative to VCC, risking unreliable switching. For 3.3 V systems, use 74HC32PW-Q100 instead, which has CMOS-level inputs (VIH = 0.7×VCC) and is rated down to 2.0 V.
What is the purpose of the input clamp diodes in this OR gate?
The internal clamp diodes protect inputs from voltage excursions beyond GND or VCC by shunting excess current when used with external series resistors. This enables safe interfacing with signals up to VCC + 0.5 V (e.g., 5.5 V on a 5 V rail), common in mixed-voltage automotive domains like CAN transceiver I/O or sensor bias networks.
Does the TSSOP14 package require special PCB layout considerations?
Yes - the side-wettable flanks demand controlled solder paste deposition and precise stencil aperture design to ensure reliable fillet formation for AOI. Thermal pad (if present in variant) is not applicable here; this TSSOP14 has no exposed pad. Maintain ≥0.2 mm solder mask clearance around all pins and use IPC-7351B compliant land patterns for SOT402-1.
