Product details
Overview
74HC1G32GW-Q100 from Nexperia is a single 2-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V, CMOS input levels, and symmetrical output impedance. It implements basic Boolean OR logic in compact TSSOP5 packaging and is used in vehicle body control modules for discrete signal combination and fault-status aggregation.
For engineers reviewing the 74HC1G32GW-Q100 datasheet, 74HC1G32GW-Q100 pinout, 74HC1G32GW-Q100 application, or 74HC1G32GW-Q100 equivalent, this device serves as a low-power, high-noise-immunity logic gate for automotive signal conditioning where TTL compatibility is not required and precise propagation delay matching (tpd = 7–23 ns) matters.
Technical Context
This device implements a single 2-input positive-logic OR function (Y = A + B) with clamped inputs enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors. Its CMOS input structure ensures high noise immunity and low static power consumption (ICC ≤ 20 μA at VCC = 6.0 V).
It operates across two temperature ranges (−40 °C to +85 °C and −40 °C to +125 °C), supports dynamic loading up to 50 pF, and delivers balanced tPLH/tPHL propagation delays - critical for timing-critical automotive subsystems such as lighting control and sensor fusion logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A + B); enables discrete signal aggregation without microcontroller intervention. |
| Supply Voltage Range | 2.0 V to 6.0 V; supports direct interface with 3.3 V and 5 V automotive sub-systems. |
| Propagation Delay | 7 ns (typ, VCC = 6.0 V, CL = 50 pF); ensures deterministic timing in safety-relevant combinational logic paths. |
| Input Voltage Levels | CMOS-compatible (VIH ≥ 4.2 V @ VCC = 6.0 V; VIL ≤ 1.8 V); eliminates need for level-shifting when driven by same-supply logic. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; sustains handling and board-level transients in automotive manufacturing environments. |
| Operating Temperature | −40 °C to +125 °C; qualified per AEC-Q100 Grade 1 for under-hood and cabin control unit deployment. |
| Output Drive | ±2.6 mA (VOH/VOL guaranteed); sufficient to drive multiple 74HC-series inputs or small LED indicators directly. |
Pinout & Package
TSSOP5 plastic thin shrink small outline package (SOT353-1), 5-lead, body width 1.25 mm, lead pitch 0.65 mm, thermal padless, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input B | Active-HIGH CMOS input; accepts 0 V to VCC; clamped to support overvoltage tolerance with series resistor. |
| 2 (A) | Data input A | Active-HIGH CMOS input; electrically identical to Pin 1; dual-input OR requires both asserted for HIGH output. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance to maintain noise immunity and stable logic thresholds. |
| 4 (Y) | Data output Y | Push-pull CMOS output; drives HIGH to ≥5.63 V (VCC = 6.0 V) or LOW to ≤0.33 V under 2.6 mA load. |
| 5 (VCC) | Positive supply | Primary power rail; decoupling capacitor (100 nF) recommended within 5 mm to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient; includes latch-up immunity >100 mA per JESD78 Class II Level B. |
| Symmetrical output impedance | Equal rise/fall time performance (tPLH ≈ tPHL); minimizes duty-cycle distortion in clocked or pulse-width-sensitive paths. |
| Clamped inputs with current limiting | Integrated diodes allow safe interface to signals up to VCC + 0.5 V using external resistors - reduces external protection components. |
| Low dynamic power dissipation | CPD = 19 pF; enables <1 μW static power at 1 MHz toggle rate with 5 V supply - critical for always-on vehicle modules. |
| Wide VCC operating range | 2.0 V to 6.0 V operation supports legacy 5 V and modern 3.3 V/2.5 V domains without voltage translation. |
Applications
| Body Control Module Logic | LED Driver Enable Combining |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT1G32GW-Q100 | TTL-compatible inputs (VIH = 2.0 V min @ VCC = 4.5–5.5 V); higher input current draw (ΔICC up to 850 μA per input). | Required when interfacing legacy 5 V TTL sources; unsuitable for battery-powered nodes due to higher static current. | Select only when driving source is strictly TTL-level; otherwise prefer HC version for lower power and wider VCC flexibility. |
| SN74LVC1G32DBVR | Lower VCC range (1.65–5.5 V); LVTTL inputs; higher speed (tpd = 3.5 ns typ @ 3.3 V); non-automotive qualified. | Used in consumer-grade infotainment peripherals; lacks AEC-Q100 qualification and extended temperature support. | Acceptable for non-safety automotive subsystems (e.g., center console) where qualification is waived and speed is prioritized. |
Compared with 74HC1G32GW-Q100, the 74HCT1G32GW-Q100 trades CMOS input compatibility for TTL interoperability at higher quiescent current, while SN74LVC1G32DBVR offers faster switching but forfeits automotive qualification and high-temperature operation - making the HC variant optimal for robust, low-power, wide-VCC automotive logic.

FAQ
What is the maximum allowable supply voltage for 74HC1G32GW-Q100?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks violating static characteristics and may cause accelerated parametric drift or latent damage, especially at elevated temperatures. Designers should maintain VCC ≤ 6.0 V with ±5 % tolerance for reliable long-term operation.
Can 74HC1G32GW-Q100 drive a 50 pF capacitive load reliably?
Yes - the device is fully characterized for CL = 50 pF across its full temperature and voltage range, with guaranteed tpd ≤ 23 ns at VCC = 4.5 V and Tamb = +125 °C. Output drive strength (±2.6 mA) ensures clean edges into this load without excessive ringing or undershoot when properly decoupled and routed.
Does this part support mixed-voltage interfacing, e.g., 3.3 V inputs with 5 V supply?
No - input voltage limits are referenced to VCC, so VI must remain between 0 V and VCC. Applying 3.3 V to an input while VCC = 5 V is acceptable (within 0–VCC), but applying 5 V while VCC = 3.3 V violates the absolute maximum rating (VI > VCC + 0.5 V). Clamping diodes only protect against brief excursions beyond those bounds when current-limited.
How does the input clamping feature affect PCB design?
The integrated input clamp diodes allow safe connection to signals exceeding VCC, provided a series current-limiting resistor restricts IIK to ≤ ±20 mA. For example, a 1 kΩ resistor limits current to ~3 mA for a 3.3 V signal applied to a 2.5 V powered device - enabling simple level-tolerant interfaces without external diodes or translators.
