Product details
Overview
74AHC1G32W5-7 from Diodes Incorporated is a single 2-input positive OR gate in SOT25 package, operating from 2.0V to 5.5V supply, delivering ±8 mA output drive at 5.0V, with Schmitt-trigger inputs for noise immunity and CMOS low-power operation. It performs the Boolean function Y = A + B and is used in logic-level translation and signal combining in portable consumer electronics.
For engineers reviewing the 74AHC1G32W5-7 datasheet, 74AHC1G32W5-7 pinout, 74AHC1G32W5-7 application, or 74AHC1G32W5-7 equivalent, key selection criteria include input voltage thresholds (VIH/VIL), propagation delay (tpd ≤ 7.0 ns @ 5V/15pF), output drive capability, ESD robustness (2 kV HBM), and SOT25 footprint compatibility.
Technical Context
This device implements a non-inverting OR logic function with rail-to-rail CMOS output swing and Schmitt-trigger inputs that tolerate slow edge rates-enabling reliable operation in noisy or high-impedance signal environments. Its dual-voltage capability (2.0–5.5V) supports mixed-supply system interfacing.
The 74AHC1G32W5-7 uses standard push-pull output stages without internal pull-ups/downs, requires no external biasing, and features latch-up immunity (>100 mA per JESD78 Class II) and full ESD protection (2 kV HBM, 1 kV CDM, 200 V MM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Positive OR (Y = A + B); enables signal merging or active-high enable logic |
| Supply Voltage Range | 2.0 V to 5.5 V; supports direct interface with 3.3 V and 5 V logic domains |
| Propagation Delay | ≤ 7.0 ns @ VCC = 5 V, CL = 15 pF; ensures timing compliance in sub-10 ns logic paths |
| Output Drive | ±8 mA @ 5 V; sufficient to drive multiple 74AHC inputs or small capacitive loads |
| Input Thresholds | VIH = 3.85 V, VIL = 1.65 V @ VCC = 5.5 V; provides 1.2 V noise margin under worst-case conditions |
| ESD Protection | 2 kV HBM, 1 kV CDM, 200 V MM; meets industrial handling requirements without external protection |
Pinout & Package
SOT25 (5-pin SC-74A) package: compact surface-mount outline with 0.95 mm pitch, 2.8 mm × 2.9 mm footprint, and exposed thermal pad not present. Compatible with standard reflow profiles and automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First OR operand; Schmitt-triggered for noise rejection on slow-rising/falling signals |
| B | Data Input | Second OR operand; electrically identical to Pin A, fully interchangeable |
| GND | Ground Reference | Return path for all internal logic and output current; must be low-impedance |
| Y | Data Output | Push-pull CMOS output; drives high/low actively-no pull-up required |
| VCC | Supply Voltage | Primary power rail; decoupling capacitor (0.1 µF) recommended within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables clean switching with input rise/fall times up to 100 ns/V-eliminates need for external RC filtering |
| Wide supply range | Operates across 2.0–5.5 V without level-shifting circuitry-reduces BOM count in multi-rail systems |
| Low static current | ICC ≤ 40 µA over full temperature range-critical for battery-powered always-on logic nodes |
| Green packaging | SOT25 molded with halogen-free, RoHS-compliant compound-meets IPC-1752A environmental reporting |
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 |
|---|---|---|---|
| SN74AHC1G32DBVR | Same logic function and SOT-23-5 package; VIH/VIL thresholds differ slightly (VIH = 3.5 V min @ VCC = 4.5 V) | TI part has tighter propagation delay variation (±0.5 ns vs ±1.5 ns) but lower ESD rating (1.5 kV HBM) | Select for tighter timing budgets where ESD environment is controlled |
| 74LVC1G32GW,125 | NXP variant in SOT353; operates down to 1.65 V, but max VCC = 5.5 V same; IO = ±24 mA @ 3.3 V | Lower voltage support enables 1.8 V domain interfacing; higher drive at 3.3 V improves fanout to LVC loads | Select when interfacing with 1.8 V logic or requiring higher sink current at 3.3 V |
Compared with SN74AHC1G32DBVR and 74LVC1G32GW,125, the 74AHC1G32W5-7 offers superior ESD robustness (2 kV HBM) and guaranteed Schmitt-trigger input behavior-making it preferred for noisy industrial or consumer front-panel interfaces where input edge integrity is critical.

FAQ
What is the maximum operating temperature for the 74AHC1G32W5-7?
The 74AHC1G32W5-7 is rated for continuous operation from −40°C to +125°C ambient temperature. This specification is validated per Recommended Operating Conditions and confirmed by electrical characterization data across temperature extremes in the DS35174 datasheet, including output drive and propagation delay performance at −40°C and +125°C.
Can unused inputs be left floating?
No. Unused inputs must be tied to VCC or GND per Note 3 in the datasheet. Floating inputs may cause excessive ICC due to intermediate voltage states triggering both PMOS and NMOS conduction paths-leading to increased power consumption and potential logic instability.
Does the 74AHC1G32W5-7 support 1.8 V operation?
No. The absolute minimum supply voltage is 2.0 V per Recommended Operating Conditions. At 1.8 V, the device fails to meet VOH/VOL specifications and may exhibit undefined logic states or excessive propagation delay. For 1.8 V systems, consider the 74LVC1G32 series instead.
Is the SOT25 package lead-free and RoHS compliant?
Yes. The 74AHC1G32W5-7 uses lead-free finish and complies with EU Directive 2002/95/EC (RoHS), including all applicable exemptions. The molding compound is halogen-free ("Green" compound), and the part marking includes RoHS-compliant identification per Diodes Incorporated's AP02001 pad layout documentation.
