Product details
Overview
74HCT1G32GV,125 from Nexperia is a single 2-input OR gate logic IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply range, -40 °C to +125 °C operating temperature, SC-74A (SOT753) 5-pin package, and 10 ns typical propagation delay at VCC = 4.5 V / CL = 50 pF. It serves as a compact combinatorial logic element in power-constrained industrial control signal conditioning.
For engineers reviewing the 74HCT1G32GV,125 datasheet, 74HCT1G32GV,125 pinout, 74HCT1G32GV,125 application, or 74HCT1G32GV,125 equivalent, key selection criteria include TTL-level input compatibility, guaranteed operation up to +125 °C, low dynamic power dissipation (CPD = 20 pF), and SC-74A footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements standard positive-logic OR functionality (Y = A + B) using CMOS technology with TTL-compatible input voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V). It features symmetrical output drive capability (±2.0 mA) and balanced propagation delays for predictable timing behavior in synchronous logic paths.
Input clamp diodes enable safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The design supports stable operation across industrial and extended-temperature environments without derating until ambient exceeds +85 °C, where thermal resistance governs power dissipation limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B); enables basic Boolean summing of digital control signals. |
| Supply Voltage Range | 4.5 V to 5.5 V; ensures compatibility with 5 V TTL systems and robust noise margin under rail variation. |
| Propagation Delay | 10 ns typical (A/B → Y, VCC = 4.5 V, CL = 50 pF); supports reliable timing in sub-100 MHz combinational paths. |
| Output Drive | ±2.0 mA at VCC = 4.5 V; sufficient to drive one 74-series TTL input or multiple CMOS loads without buffering. |
| Operating Temperature | -40 °C to +125 °C; qualified for under-hood automotive modules, industrial PLC I/O stages, and high-ambient sensor interfaces. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max (VCC = 4.5–5.5 V); guarantees interoperability with legacy 5 V TTL outputs. |
| Power Dissipation Cap. | CPD = 20 pF; enables accurate dynamic power estimation (PD = CPD × VCC² × fi) for thermal budgeting. |
Pinout & Package
74HCT1G32GV,125 is housed in an SC-74A (SOT753) plastic surface-mounted package: 5-terminal, 1.1 mm × 1.7 mm body, 0.65 mm pitch, no exposed thermal pad, and pin 1 index located below marking "T32" on lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input B | Active-HIGH logic input; accepts TTL-level signals; clamped to GND/VCC via internal diodes. |
| 2 (A) | Data input A | Active-HIGH logic input; electrically identical to Pin 1; supports wired-OR expansion with external pull-ups. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current; must be low-impedance for noise immunity. |
| 4 (Y) | Data output Y | CMOS push-pull output; drives HIGH/LOW actively; fan-out ≥ 10 LS-TTL loads at VCC = 4.5 V. |
| 5 (VCC) | Positive supply | Primary power rail; decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply enables direct connection to legacy 5 V microcontrollers and peripheral drivers. |
| Extended temperature range | Guaranteed operation from -40 °C to +125 °C supports deployment in engine control units, motor drives, and outdoor industrial enclosures. |
| Low dynamic power | CPD = 20 pF allows precise calculation of switching power (e.g., 450 μW at 1 MHz, 5 V), critical for battery-backed subsystems. |
| Input clamp diodes | Enable safe interface to voltages > VCC using series resistors-eliminates need for external level-shifting components. |
| ESD robustness | HBM > 2000 V and CDM > 1000 V reduce handling sensitivity and improve field reliability in automated assembly lines. |
Applications

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 |
|---|---|---|---|
| 74LVC1G32GV,125 | Lower VCC range (1.65–5.5 V); CMOS input thresholds (VIH = 0.7×VCC); 4 ns tpd at 3.3 V. | Better suited for mixed-voltage 3.3 V/5 V systems; not TTL-compatible; requires level translation when interfacing 5 V TTL sources. | Select when operating below 4.5 V or requiring faster speed at 3.3 V; avoid if interfacing legacy 5 V TTL outputs. |
| SN74LVC1G32DBVR | Same logic function; SOT-23-5 package; VIH/VIL referenced to VCC; 3.5 ns tpd at 3.3 V; TI's enhanced ESD rating (HBM > 8 kV). | Higher ESD tolerance benefits high-handling-volume manufacturing; SOT-23-5 footprint differs from SC-74A (0.95 mm vs. 0.65 mm pitch). | Choose for TI-design ecosystems or where higher HBM robustness is mandatory; verify PCB land pattern compatibility. |
Compared with 74HCT1G32GV,125, the 74LVC1G32GV,125 offers wider supply flexibility and speed at 3.3 V but lacks native TTL input compatibility, while SN74LVC1G32DBVR provides superior ESD protection and faster timing but requires mechanical redesign due to different lead pitch and package outline.

FAQ
Can 74HCT1G32GV,125 operate reliably at 4.2 V supply?
No. The 74HCT1G32GV,125 is specified only for 4.5 V to 5.5 V operation per JEDEC JESD8C compliance. At 4.2 V, VIH minimum (2.0 V) remains met, but VOH and VOL margins degrade beyond specification limits, risking downstream logic misreads. Use 74LVC1G32GV,125 for 4.2 V systems.
Does this part support hot-swap or live-insertion?
No. The 74HCT1G32GV,125 lacks powered-off protection circuitry. Applying input signals before VCC stabilization may forward-bias internal clamp diodes, causing latch-up or excessive current draw. Always sequence VCC before applying inputs in hot-swap applications.
What is the maximum capacitive load this output can drive without timing degradation?
The datasheet specifies timing parameters up to 50 pF load capacitance. Driving >50 pF increases propagation delay nonlinearly-e.g., 100 pF raises tpd from 10 ns to ~18 ns at VCC = 4.5 V. For heavier loads, add a buffer stage or use a higher-drive logic family like 74AHCT.
Is the SC-74A (SOT753) package compatible with reflow profiles for lead-free soldering?
Yes. The SC-74A package is rated for standard IPC/JEDEC J-STD-020D Level 1 moisture sensitivity and withstands peak reflow temperatures up to 260 °C for 30 seconds. Pre-bake is not required unless exposed to >60% RH for >168 hours.
