Product details
Overview
74HCT1G32GW-Q100 from Nexperia is a single 2-input OR gate logic IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5.5 V max supply, and propagation delay of 10 ns (typ) at VCC = 4.5 V/CL = 50 pF - deployed in body control modules for discrete signal combination.
For engineers reviewing the 74HCT1G32GW-Q100 datasheet, 74HCT1G32GW-Q100 pinout, 74HCT1G32GW-Q100 application, or 74HCT1G32GW-Q100 equivalent, key selection criteria include automotive temperature compliance, TTL-level input compatibility, TSSOP5 package footprint, and sub-25 ns worst-case propagation delay under 125 °C operation.
Technical Context
This device implements a single 2-input positive-logic OR function (Y = A + B) using silicon-gate CMOS technology with TTL-level input thresholds, enabling direct interfacing with legacy 5 V TTL outputs without level translation. Input clamp diodes allow safe overvoltage tolerance when used with current-limiting resistors.
It features symmetrical output drive capability (±2.0 mA at VCC = 4.5 V), balanced tPLH/tPHL propagation delays, and latch-up immunity exceeding 100 mA per JESD78 Class II Level B - critical for robustness in noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B); enables signal merging in safety-critical control paths |
| Supply Voltage Range | 4.5 V to 5.5 V (recommended); supports stable operation across automotive battery transients |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V; ensures reliable recognition of 5 V TTL signals |
| Propagation Delay | 10 ns (typ), 27 ns (max) at VCC = 4.5 V/CL = 50 pF/TA = 125 °C; meets timing budgets in fast-response subsystems |
| Output Drive | ±2.0 mA at VCC = 4.5 V; sufficient to drive multiple 74HCT inputs or small capacitive loads (<30 pF) |
| Operating Temperature | -40 °C to +125 °C; qualified per AEC-Q100 Grade 1 for engine bay and chassis-mounted ECUs |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; withstands handling and assembly ESD events in automotive production |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second logic input; accepts TTL-level signals up to VCC; includes internal clamp diode to GND/VCC |
| 2 | A | Primary logic input; identical electrical characteristics to Pin 1; enables dual-signal OR logic |
| 3 | GND | Ground reference (0 V); must be low-impedance connection to minimize switching noise coupling |
| 4 | Y | CMOS-compatible output; drives high/low with symmetrical impedance; fan-out ≥ 10 HCT loads |
| 5 | VCC | Positive supply (4.5–5.5 V); requires local 100 nF ceramic decoupling within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient; eliminates need for additional reliability screening |
| TTL-level input compatibility | VIH = 2.0 V min / VIL = 0.8 V max at VCC = 4.5–5.5 V; interfaces directly with legacy 5 V microcontrollers and sensors |
| Symmetrical output drive | IOH = IOL = ±2.0 mA at VCC = 4.5 V; ensures consistent rise/fall times and reduced signal skew |
| Input clamp diodes | Enables safe interface to voltages > VCC using external current-limiting resistors; prevents damage during bus contention |
| Low dynamic power | CPD = 20 pF; enables <1 mW typical dynamic power at 1 MHz/5 V, reducing thermal load in dense PCB layouts |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT1G32GV-Q100 | SC-74A (SOT753) package: 3.1 mm × 1.7 mm body, 0.95 mm pitch; 0.26 mm height vs. TSSOP5's 0.9 mm | Preferred where board space allows larger footprint but lower profile is needed; same electrical specs and AEC-Q100 Grade 1 rating | Select for manual assembly or reflow profiles incompatible with TSSOP5's fine pitch |
| 74HCT1G32GZ-Q100 | XSON5 (SOT8065-1) package: 1.1 mm × 0.85 mm, side-wettable flanks, no leads; 0.5 mm height | Required for ultra-dense automotive modules with automated optical inspection (AOI); identical logic and temp range | Select when PCB area is constrained and AOI-capable solder paste printing is available |

FAQ
What is the maximum supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 4.5 V to 5.5 V. Operation above 5.5 V risks exceeding input/output voltage limits and invalidates AEC-Q100 qualification margins. Sustained use beyond 5.5 V may cause accelerated parametric drift or latent failure in automotive environments.
Can this OR gate drive a 50 pF capacitive load at 125 °C?
Yes - the datasheet specifies tPD = 27 ns (max) at VCC = 4.5 V, CL = 50 pF, and TA = 125 °C. Output drive capability remains ±2.0 mA under these conditions, ensuring clean edges and adequate noise margin even at temperature extremes.
Is there a difference in input threshold between 74HC1G32GW-Q100 and 74HCT1G32GW-Q100?
Yes: the HC version uses CMOS-level inputs (VIH = 3.15 V min at VCC = 4.5 V), while the HCT version uses TTL-level inputs (VIH = 2.0 V min). This allows the HCT variant to interface directly with legacy 5 V TTL outputs without level shifters - a key differentiator for mixed-technology automotive systems.
Does the TSSOP5 package require special PCB layout considerations?
Yes - the 0.65 mm lead pitch demands controlled-depth solder paste deposition and stencil aperture design per IPC-7525. A thermal relief on Pin 3 (GND) and Pin 5 (VCC) is recommended, and decoupling capacitance must be placed within 5 mm of Pin 5 to maintain signal integrity at 100 MHz edge rates.
