Product details
Overview
74VHC32D,118 from Nexperia is a quad 2-input OR gate IC in SO14 package, operating at 2.0–5.5 V supply, delivering propagation delays as low as 2.8 ns (typ.) at 5 V with 15 pF load, and supporting industrial temperature range (−40 °C to +125 °C). It provides discrete logic-level OR functionality for signal combining in digital control, bus arbitration, and status aggregation circuits.
For engineers reviewing the 74VHC32D,118 datasheet, 74VHC32D,118 pinout, 74VHC32D,118 application, or 74VHC32D,118 equivalent, key selection criteria include CMOS input compatibility, guaranteed 8 mA output drive, Schmitt-trigger input tolerance for noisy environments, and SO14 package suitability for legacy PCB layouts requiring pin-compatible LSTTL replacement.
Technical Context
The 74VHC32D,118 implements four independent 2-input OR gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC Std. 7-A and pin-compatible with Low-power Schottky TTL. Its inputs accept voltages up to 7.0 V - exceeding VCC - enabling mixed-voltage interfacing without level shifters.
Each gate features balanced propagation delays (tPLH ≈ tPHL), Schmitt-trigger action on all inputs for noise immunity, and operates across −40 °C to +125 °C with static VIH/VIL thresholds defined for 2.0 V, 3.0 V, and 5.5 V supply rails. Output drive capability is specified at ±8 mA under 4.5–5.5 V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR (A + B = Y per gate) |
| Supply Voltage Range | 2.0 V to 5.5 V - supports 3.3 V and 5 V systems without voltage translation |
| Propagation Delay | 2.8 ns (typ.) at VCC = 5 V, CL = 15 pF - enables >100 MHz toggle rates in clean loads |
| Output Drive | ±8 mA at VCC = 4.5–5.5 V - sufficient to drive 10 LSTTL loads or moderate capacitive buses |
| Input Voltage Tolerance | −0.5 V to +7.0 V - allows safe interfacing with higher-voltage signals or open-drain pull-ups |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, industrial control, and power-conversion monitoring |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 for board-level robustness |
Pinout & Package
74VHC32D,118 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, and standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible LSTTL replacement | Direct drop-in substitute for 74LS32 in existing designs without layout change |
| Schmitt-trigger inputs | Eliminates false triggering from slow-rising or noisy control signals (e.g., mechanical switch debouncing) |
| Wide input voltage tolerance | Accepts inputs up to 7.0 V regardless of VCC - enables direct connection to 5 V microcontroller GPIO driving 3.3 V logic |
| High noise immunity | Input hysteresis ≥0.3 V at VCC = 5 V ensures reliable operation in electrically noisy industrial environments |
| Low quiescent current | ICC ≤ 40 μA at VCC = 5.5 V - suitable for battery-backed or always-on status-monitoring circuits |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHCT32D,118 | TTL-compatible inputs (VIH = 2.0 V min); identical SO14 package and pinout | Required when interfacing with legacy 5 V TTL outputs or microcontrollers lacking 3.3 V-tolerant GPIO | Select when driving from 5 V LSTTL sources without level shifters |
| SN74LVC32APWR | Lower VCC range (1.65–5.5 V); 24 mA output drive; different pinout (TSSOP-14) | Supports 1.8 V logic domains and higher fan-out but requires PCB redesign | Choose for new designs needing 1.8 V compatibility or stronger drive; not pin-compatible |
Compared with 74VHC32D,118, the 74VHCT32D,118 offers guaranteed TTL-level input recognition at 5 V systems but sacrifices 3.3 V input compatibility, while SN74LVC32APWR enables lower-voltage operation and higher drive strength at the cost of layout rework and non-drop-in replacement.

FAQ
What is the maximum clock frequency supported by the 74VHC32D,118?
The 74VHC32D,118 is a combinational logic device without internal clocking, so it does not have a "clock frequency." Its usable toggle rate depends on propagation delay and load capacitance: with 15 pF load and 5 V supply, tpd ≤ 5.5 ns supports signal transitions up to ~100 MHz in ideal conditions. Real-world limits are set by PCB trace capacitance and driver strength.
Can the 74VHC32D,118 interface directly with 5 V microcontroller outputs?
Yes - the 74VHC32D,118 accepts input voltages up to +7.0 V, making it safe for direct connection to 5 V CMOS or TTL outputs. Its VIH threshold is 3.85 V at VCC = 5.5 V, ensuring reliable HIGH recognition from standard 5 V logic drivers without external level shifting.
Is the SO14 package of 74VHC32D,118 RoHS compliant and lead-free?
Yes - the 74VHC32D,118 in SOT108-1 (SO14) package is manufactured per RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination and halogen-free molding compound, as confirmed in Nexperia's official compliance documentation dated April 2024.
Does the 74VHC32D,118 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied to VCC or GND to prevent floating states and increased ICC. The datasheet explicitly prohibits leaving inputs unconnected due to CMOS gate susceptibility to noise-induced shoot-through current; Schmitt-trigger inputs do not eliminate this requirement.
