Product details
Overview
74AHCT1G32GW,125 from Nexperia is a single 2-input OR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5-pin TSSOP5 (SOT353-1) package, −40 °C to +125 °C operating range, and propagation delay as low as 3.3 ns (typ) at VCC = 5.0 V with CL = 15 pF. It serves as a level-translating combinational logic element in mixed-voltage digital interfaces.
For engineers reviewing the 74AHCT1G32GW,125 datasheet, 74AHCT1G32GW,125 pinout, 74AHCT1G32GW,125 application, or 74AHCT1G32GW,125 equivalent, this device is selected for low-power, rail-to-rail compatible OR logic in industrial control I/O expansion, sensor interface signal conditioning, and microcontroller peripheral bus arbitration where TTL-level compatibility and overvoltage-tolerant inputs are required.
Technical Context
The 74AHCT1G32GW,125 implements a single positive-logic OR function (Y = A + B) using CMOS transistor technology with TTL-level input switching thresholds. Its input stage accepts 0–5.5 V signals regardless of VCC (2.0–5.5 V), enabling use as a voltage translator between 3.3 V and 5 V domains.
Propagation delays are balanced (tPLH ≈ tPHL), output drive strength is symmetrical (IOH/IOH = −8.0 mA / 8.0 mA at VCC = 4.5 V), and static noise margins exceed 1.2 V at VCC = 5.0 V due to defined VIH/VIL and VOH/VOL specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B); no internal latching or timing elements |
| Input Compatibility | TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V); enables direct connection to legacy 5 V TTL outputs |
| Supply Range | 4.5 V to 5.5 V (recommended); supports stable operation across full industrial temperature range |
| Propagation Delay | 3.3 ns (typ) at VCC = 5.0 V, CL = 15 pF; ensures sub-10 ns timing in high-speed digital control paths |
| Output Drive | ±8.0 mA at VCC = 4.5 V; sufficient to drive 10 LSTTL loads or 15 pF PCB trace capacitance |
| Operating Temperature | −40 °C to +125 °C; qualified for under-hood, motor control, and factory automation environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; robust against handling and board-level electrostatic events |
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, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Input | Second logic input; overvoltage tolerant to 5.5 V independent of VCC |
| 2 (A) | Input | Primary logic input; accepts TTL or CMOS swing; pin 1 index located below marking |
| 3 (GND) | Ground Reference | 0 V return path for all internal circuitry and output current sinking |
| 4 (Y) | Output | CMOS push-pull output; drives HIGH to ≥3.94 V (VCC = 4.5 V, IO = −8 mA) or LOW to ≤0.36 V |
| 5 (VCC) | Supply Voltage | Positive supply rail; must be decoupled locally with 100 nF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Accepts up to 5.5 V on A/B pins even when VCC = 3.3 V - enables safe level translation without external resistors |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduced signal distortion |
| Balanced propagation delays | tPLH and tPHL differ by <10% - critical for glitch-free timing in synchronous control logic |
| High noise immunity | DC noise margin >1.2 V at VCC = 5.0 V - suppresses false triggering from EMI or crosstalk in noisy industrial settings |
| Wide temperature qualification | Specified from −40 °C to +125 °C - eliminates derating concerns in extended ambient applications |
Applications
| Industrial PLC I/O Expansion | Sensor Signal Conditioning |
|---|---|
Use Scenario: Aggregating multiple limit switch or proximity sensor status signals into a single interrupt line for a microcontroller. IC Role / Device Role / Timing Role: Combinational OR gate performing real-time logical OR of up to two discrete sensor inputs before routing to MCU GPIO.

| Microcontroller Peripheral Arbitration | Legacy Bus Interface Translation |
Use Scenario: Resolving simultaneous SPI chip-select requests from multiple peripherals sharing one controller. IC Role / Device Role / Timing Role: OR gate combining CS signals to generate a master enable for shared power or clock domains. Use Value: Enables zero-software-latency coordination of peripheral power sequencing and avoids bus contention during startup. | Use Scenario: Interfacing a 3.3 V FPGA I/O bank to a 5 V EEPROM or display driver with TTL-level signaling. IC Role / Device Role / Timing Role: Level-shifting OR gate accepting 5 V TTL inputs and driving 3.3 V CMOS-compatible outputs. Use Value: Achieves bidirectional voltage translation without external biasing or active translators-reducing BOM count and layout area. |
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 |
|---|---|---|---|
| 74AHCT1G32GV,125 | Same logic function and electrical specs; SC-74A (SOT753) package - 2.7 mm × 1.7 mm vs TSSOP5's 2.2 mm × 1.35 mm | Lower thermal resistance (85 °C/W vs 110 °C/W) but larger footprint; preferred for higher ambient or manual assembly | Select GV for hand-soldering or thermal-limited layouts; GW for space-constrained automated SMT lines. |
| SN74LVC1G32DBVR | CMOS-level inputs (VIH = 2.0 V @ VCC = 3.3 V), wider VCC range (1.65–5.5 V), but only rated to +85 °C | Lacks automotive/industrial temperature support; unsuitable for systems requiring >85 °C operation or guaranteed TTL compatibility | Choose DBVR only for cost-sensitive consumer designs with 3.3 V-only rails and ambient <85 °C. |
Compared with 74AHCT1G32GV,125, the GW variant offers superior board-area efficiency and reflow compatibility; versus SN74LVC1G32DBVR, it delivers guaranteed TTL input behavior and full −40 °C to +125 °C qualification - essential for industrial control and motor drive applications.

FAQ
Can 74AHCT1G32GW,125 operate with a 3.3 V supply?
No - the 74AHCT variant is specified only for VCC = 4.5 V to 5.5 V. For 3.3 V operation, use the 74AHC1G32GW,125 (CMOS-input version), which supports 2.0–5.5 V. Using 3.3 V on AHCT risks undefined input thresholds and marginal VOH/VOL performance.
What is the maximum capacitive load this OR gate can drive reliably?
The device is characterized up to 50 pF (CL) with guaranteed tpd ≤ 9.0 ns at VCC = 5.0 V. Driving >50 pF increases propagation delay nonlinearly and may cause ringing; for loads >50 pF, add a series resistor (22–47 Ω) near the output to dampen reflections.
Is pin 1 orientation marked on the 74AHCT1G32GW,125 package?
Yes - per datasheet Figure 6 and Table 2, the pin 1 indicator is a molded notch or dimple located on the lower-left corner of the TSSOP5 body, directly below the "CG" top-side marking. This aligns with JEDEC standard SOT353-1 mechanical drawing.
Does this device require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied to VCC or GND. Floating inputs cause increased ICC, unpredictable logic states, and potential oscillation due to CMOS input structure. The datasheet explicitly prohibits leaving A or B unconnected; no pull-up/down resistors are needed if properly terminated.
