Product details
Overview
74HCT32D-Q100,118 from Nexperia is an automotive-qualified quad 2-input OR gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and propagation delay as low as 9 ns at VCC = 4.5 V. It integrates input clamp diodes for overvoltage-tolerant interfacing and meets AEC-Q100 Grade 1 requirements for engine control units and body electronics.
For engineers reviewing the 74HCT32D-Q100,118 datasheet, 74HCT32D-Q100,118 pinout, 74HCT32D-Q100,118 application, or 74HCT32D-Q100,118 equivalent, this page delivers verified functional identity, SO14 pin mapping, automotive thermal and ESD specs (HBM >2000 V), and direct substitution guidance against industry-standard logic alternatives.
Technical Context
This device implements four independent OR logic functions (A + B → Y) 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 seamless integration with legacy 5 V microcontroller GPIOs and sensor interface circuits. Its symmetrical output drive (±4.0 mA at VCC = 4.5 V) ensures matched rise/fall times and low skew across all four gates.
Designed for automotive environments, it features latch-up immunity exceeding 100 mA per JESD78 Class II Level B, operates up to 125 °C ambient, and supports robust noise margins (typical 1.2 V DCNM at VCC = 5 V). Input clamping diodes allow safe use of current-limiting resistors when interfacing to signals exceeding VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate (four independent A+B→Y functions) |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail with ±5% tolerance margin |
| Propagation Delay (tpd) | 11 ns typ / 36 ns max at VCC = 4.5 V, CL = 50 pF - enables reliable timing in <30 MHz combinatorial paths |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - ensures compatibility with TTL-output devices and 5 V MCU I/O |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LS-TTL loads or 20 pF PCB trace capacitance |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
| ESD Protection | HBM >2000 V, CDM >1000 V - protects against handling and assembly electrostatic events |
Pinout & Package
74HCT32D-Q100,118 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 4A, 9A, 12A | Input A of Gate 1–4 | First OR input per gate; accepts TTL-level signals; clamped to VCC/GND |
| 2B, 5B, 10B, 13B | Input B of Gate 1–4 | Second OR input per gate; identical electrical behavior to A inputs |
| 3Y, 6Y, 8Y, 11Y | Output Y of Gate 1–4 | Active-high OR result; drives loads up to ±4.0 mA; rail-to-rail swing |
| 7 | GND | Ground reference (0 V); mandatory connection for logic reference and power return |
| 14 | VCC | Positive supply (4.5–5.5 V); powers all four gates and internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive operation from -40 °C to +125 °C ambient, including temperature cycling and humidity testing |
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates level-shifting when interfacing with legacy 5 V controllers |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures equal rise/fall times (<22 ns difference at VCC = 4.5 V), reducing signal distortion |
| Input clamp diodes | Enable safe interface to voltages > VCC using external current-limiting resistors - critical for sensor signal conditioning with overvoltage transients |
| Low dynamic power | CPD = 28 pF - limits switching power to <1.5 mW at 1 MHz with 50 pF load, supporting low-power body control modules |
Applications
| Engine Control Unit (ECU) Diagnostics | Automotive Body Control Module (BCM) |

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 |
|---|---|---|---|
| SN74HCT32DR | TTL-compatible inputs, same 4.5–5.5 V range, but rated only to +85 °C (not AEC-Q100 qualified) | Restricted to cabin/non-under-hood automotive use or industrial control; lacks Grade 1 thermal validation | Select only if operating ambient stays ≤85 °C and AEC-Q100 certification is not required. |
| 74HC32D-Q100,118 | CMOS-level inputs (VIH = 3.15 V min), wider 2.0–6.0 V supply, but incompatible with TTL outputs without level shift | Supports mixed-voltage systems (e.g., 3.3 V MCU + 5 V peripherals), but cannot directly replace TTL-driven inputs | Choose when interfacing with 3.3 V logic families or requiring extended supply flexibility - not a drop-in replacement. |

FAQ
What is the maximum allowable supply voltage for 74HCT32D-Q100,118?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Operation above 5.5 V voids AEC-Q100 qualification and risks parametric shift or accelerated wear-out; sustained use at 7.0 V will cause permanent damage per IEC 60134 limiting values.
Can 74HCT32D-Q100,118 drive a 50 pF capacitive load at 10 MHz?
Yes - with tpd = 11 ns typ and tt = 7 ns typ at VCC = 4.5 V and CL = 50 pF, it supports clean signal edges up to ~35 MHz fundamental frequency. At 10 MHz, dynamic power remains below 0.5 mW (CPD = 28 pF), well within its 500 mW total package dissipation limit at +25 °C ambient.
Is the SO14 package (SOT108-1) lead-free and RoHS compliant?
Yes - the 74HCT32D-Q100,118 uses matte tin (Sn) plating on gull-wing leads and complies fully with EU RoHS Directive 2011/65/EU and China RoHS GB/T 26572-2011. Lead content is <1000 ppm, and all six restricted substances meet threshold requirements.
Does this part support hot insertion or live swapping in powered systems?
No - it lacks hot-swap protection circuitry. Applying VCC before GND, or connecting inputs while VCC is absent, may forward-bias internal clamp diodes and cause latch-up or excessive current. Always power GND first, then VCC, and ensure all inputs are within 0 V to VCC before enabling supply.
