Product details
Overview
74HC1G32GW,125 from Nexperia is a single 2-input OR gate logic IC in TSSOP5 (SOT353-1) package, operating from 2.0 V to 6.0 V supply, with CMOS input levels, ±12.5 mA output drive, and propagation delay as low as 7 ns at 6.0 V/50 pF - used for level-shifting, signal combining, and enable logic in portable power management and sensor interface circuits.
For engineers reviewing the 74HC1G32GW,125 datasheet, 74HC1G32GW,125 pinout, 74HC1G32GW,125 application, or 74HC1G32GW,125 equivalent, this page delivers verified pin functions, temperature-rated static/dynamic specs, real-world use cases in battery-powered systems, and validated alternatives with TTL-compatible variants.
Technical Context
This device implements a single 2-input positive-logic OR function using standard CMOS silicon technology. Its inputs include clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. The output stage provides symmetrical sourcing/sinking capability with balanced propagation delays (tPLH ≈ tPHL).
It is specified across -40 °C to +125 °C and supports JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards. Input thresholds scale with VCC for the HC variant (VIH = 0.7×VCC min), ensuring robust noise immunity up to 1.8 V at VCC = 2.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A + B); enables basic decision logic in control paths. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct integration with 3.3 V and 5 V rails without level shifters. |
| Propagation Delay | 7 ns typical at VCC = 6.0 V, CL = 50 pF - suitable for sub-100 MHz timing-critical combinational logic. |
| Output Drive | ±12.5 mA - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74HC inputs (fan-out ≥ 10). |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, industrial, and extended-range embedded applications. |
| Input Clamp Diodes | Integrated - allows safe overvoltage input handling (e.g., 12 V signals via series resistor) without external protection. |
| Power Dissipation | 250 mW max at Tamb ≤ 74 °C (TSSOP5); derates 3.3 mW/K above - enables compact PCB layout without forced cooling. |
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) | Data input B | CMOS-level digital input; accepts 0 V to VCC; clamped to GND/VCC for overvoltage tolerance. |
| 2 (A) | Data input A | CMOS-level digital 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 to ≥95% VCC and LOW to ≤0.33 V at 2.6 mA load. |
| 5 (VCC) | Positive supply | Primary power rail; decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (2.0–6.0 V) | Eliminates need for separate voltage translators when interfacing mixed-supply subsystems (e.g., 3.3 V MCU to 5 V peripheral). |
| Symmetrical output impedance | Ensures matched rise/fall times (<10% skew), critical for glitch-free timing in clock gating and state-machine enable paths. |
| Latch-up immunity >100 mA | Guarantees robustness against transient current surges during hot-plug or ESD events per JESD78 Class II Level B. |
| HBM ESD rating >2000 V | Reduces risk of field failure during manual handling or board assembly without additional protection components. |
| Input transition rate support | Accepts edge rates down to 83 ns/V at 6.0 V - compatible with fast microcontroller GPIOs and FPGA outputs. |
Applications
| Portable Power Sequencing | Industrial Sensor Interface |
|---|---|
Use Scenario: Enable sequencing of three LDOs based on battery voltage and system reset status. IC Role / Device Role / Timing Role: OR gate combines "battery OK" and "reset released" signals to assert main power-enable line. Use Value: Prevents premature power-up by requiring both conditions; eliminates need for discrete diodes or microcontroller polling. |
Use Scenario: Aggregate fault flags from temperature, pressure, and humidity sensors in a PLC I/O module. IC Role / Device Role / Timing Role: Wired-OR summation node pulling shared interrupt line LOW when any sensor reports error. Use Value: Reduces MCU GPIO count by 2 pins; leverages built-in clamp diodes to tolerate mismatched sensor output voltages. |
| USB-C Port Controller Logic | Automotive Body Control Module |
Use Scenario: Generate "VBUS present" indicator from dual-source detection (CC logic + analog comparator output). IC Role / Device Role / Timing Role: Combinatorial OR resolves redundant VBUS detection paths into single status flag for USB PD controller. Use Value: Improves system reliability by eliminating single-point failure; operates reliably across full 0–6 V VBUS range. |
Use Scenario: Combine door-open and key-fob proximity signals to trigger interior lighting activation. IC Role / Device Role / Timing Role: Low-power OR gate driving LED driver enable, active only when either condition is asserted. Use Value: Draws <20 μA quiescent current at 125 °C - extends battery standby time in always-on vehicle modules. |
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,125 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V); otherwise identical pinout, package, and speed. | Required when interfacing legacy 5 V TTL outputs or microcontrollers with non-rail-to-rail GPIOs. | Select when driving from older MCUs or logic families with marginal high-level output voltage. |
| SN74LVC1G32DBVR | Lower VCC range (1.65–5.5 V); higher drive (±32 mA); smaller SC-70-5 package; no input clamp diodes. | Preferred for space-constrained 3.3 V designs needing stronger drive, but requires external overvoltage protection. | Choose for ultra-low-profile layouts where 1.65 V operation or 32 mA sink/source is mandatory. |
Compared with 74HC1G32GW,125, the 74HCT1G32GW,125 offers guaranteed TTL input compatibility at 5 V while retaining identical packaging and thermal performance; the SN74LVC1G32DBVR trades clamp diodes and 2 V minimum supply for higher drive strength and smaller footprint in 3.3 V systems.

FAQ
Is 74HC1G32GW,125 pin-compatible with 74HCT1G32GW,125?
Yes - both share identical TSSOP5 (SOT353-1) pinout, package dimensions, and terminal numbering. The only functional difference is input threshold behavior: 74HC1G32 requires CMOS-level inputs (VIH ≥ 0.7×VCC), while 74HCT1G32 accepts TTL-level inputs (VIH ≥ 2.0 V at 5 V). No PCB redesign is needed for substitution.
What is the maximum capacitive load this OR gate can drive reliably?
The 74HC1G32GW,125 is characterized up to 50 pF load capacitance with guaranteed 7–23 ns propagation delay (depending on VCC). For loads exceeding 50 pF, rise/fall times increase linearly; design margin requires limiting total trace + input capacitance to ≤45 pF for timing-critical paths at 6 V.
Can this device operate at 1.8 V supply?
No - the absolute minimum recommended VCC is 2.0 V per Table 6. At 1.8 V, VIH and VOL specifications are not guaranteed, and propagation delay increases significantly (>100 ns). For 1.8 V systems, consider the 74LVC1G32 or 74AUP1G32 families instead.
Does the TSSOP5 package have an exposed thermal pad?
No - the SOT353-1 (TSSOP5) package used for 74HC1G32GW,125 has no exposed pad. Thermal dissipation relies solely on lead-frame conduction through the five leads; PCB copper area under the package provides minimal additional cooling.
