Product details
Overview
74VHCT32PW,118 from Nexperia is a quad 2-input OR gate IC in TSSOP14 package, operating at 4.5 V to 5.5 V supply with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), propagation delay of 3.1–9.0 ns (CL = 15–50 pF), and rated for -40 °C to +125 °C ambient operation. It serves as a logic-level combiner in industrial control signal routing and digital bus arbitration circuits.
For engineers reviewing the 74VHCT32PW,118 datasheet, 74VHCT32PW,118 pinout, 74VHCT32PW,118 application, or 74VHCT32PW,118 equivalent, this page delivers verified pin functions, real-world timing behavior under load, thermal derating data for TSSOP14, and validated alternatives for logic-level compatibility and package migration.
Technical Context
This device implements four independent 2-input OR gates using high-speed Si-gate CMOS technology compliant with JEDEC Std 7-A and pin-compatible with LSTTL. Its TTL input thresholds enable direct interfacing with legacy 5 V logic families without level-shifting.
Each gate features Schmitt-trigger inputs for noise immunity, supports input voltages up to 7.0 V (exceeding VCC), and exhibits balanced tPLH/tPHL propagation delays. The TSSOP14 package (SOT402-1) provides 4.4 mm body width and thermal derating of 7.3 mW/K above 81 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR (74-series standard Boolean OR per gate) |
| Supply Voltage (VCC) | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL systems and stable operation across industrial voltage tolerances |
| Propagation Delay (tpd) | 3.1 ns (typ, CL = 15 pF) to 10.0 ns (max, CL = 50 pF, -40 °C to +125 °C) - defines maximum clock/data path timing margin in synchronous logic |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL logic levels without external biasing |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor drive, and industrial PLC environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 for board-level handling robustness |
| Power Dissipation Cap | 500 mW max at Tamb ≤ 81 °C; derates 7.3 mW/K above - constrains thermal design for TSSOP14 PCB layout |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each OR gate - accepts TTL/CMOS logic levels up to 7.0 V |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each OR gate - Schmitt-triggered for noise rejection on slow-rising signals |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | OR output per gate - drives 8 mA sink/source while maintaining VOL ≤ 0.55 V at 8 mA |
| 7 | GND | Ground reference (0 V) - must be low-impedance connection to minimize switching noise coupling |
| 14 | VCC | Positive supply - requires local 100 nF ceramic decoupling within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates need for level translators when interfacing with 74LS/74F families |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V typical - suppresses chatter on noisy control lines (e.g., pushbutton debouncing, sensor outputs) |
| Overvoltage-tolerant inputs | VI rating up to 7.0 V - allows safe connection to 5 V buses even during hot-swap or power sequencing events |
| High-speed performance | tpd ≤ 7.0 ns (typ, CL = 15 pF, VCC = 5 V) - supports >100 MHz toggle rates in non-critical paths |
| Industrial temperature range | Specified from -40 °C to +125 °C - enables use in motor drives, power supplies, and factory automation without derating |
Applications
| Industrial Control Signal Routing | Digital Bus Arbitration Logic |
|---|---|
|
Use Scenario: Combining multiple enable signals (e.g., emergency stop, interlock, mode select) to generate a unified system enable output in PLC I/O modules. IC Role / Device Role / Timing Role: Quad OR gate performing wired-OR logic aggregation with sub-10 ns propagation to meet deterministic response deadlines. Use Value: Eliminates discrete diode-OR networks, reduces board space by 60%, and guarantees monotonic output transitions under varying input slew rates. |
Use Scenario: Resolving bus master priority in multi-controller CAN or SPI systems where any active request asserts a shared BUSY line. IC Role / Device Role / Timing Role: Fast OR combiner feeding BUSY status to all masters; propagation delay directly limits arbitration latency. Use Value: Enables worst-case arbitration time ≤ 10 ns, supporting real-time bus turnaround in motion control networks. |
| Legacy TTL System Interface | Power Sequencing Monitoring |
|
Use Scenario: Interfacing modern microcontrollers (3.3 V GPIO) with legacy 5 V TTL peripherals requiring OR-combined interrupt sources. IC Role / Device Role / Timing Role: Level-shifting logic gate translating 3.3 V outputs to 5 V–compatible inputs while preserving OR function. Use Value: Avoids dedicated level shifters; VIH/VIL specs ensure correct interpretation of 3.3 V logic highs as valid TTL HIGH. |
Use Scenario: Monitoring individual rail OK signals (e.g., 12 V, 5 V, 3.3 V) to assert a single POWER_GOOD flag in industrial power supplies. IC Role / Device Role / Timing Role: Fault-tolerant OR gate where any missing rail pulls POWER_GOOD LOW via open-drain pull-down. Use Value: Provides fail-safe power-up sequencing validation with guaranteed 125 °C operation and no external components. |
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 |
|---|---|---|---|
| 74VHC32PW,118 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); operates down to 2.0 V VCC | Better suited for mixed-voltage systems (e.g., 3.3 V logic driving 5 V loads) but incompatible with pure TTL input sources | Select when interfacing with CMOS or mixed-supply logic; verify input drive strength matches VIH requirement. |
| SN74LVC32APWR | 3.3 V only (1.65–3.6 V VCC); LVCMOS thresholds; 3.5 ns tpd (CL = 50 pF) | Optimized for low-voltage portable/embedded designs; lacks 5 V tolerance and industrial temp rating | Prefer for battery-powered or FPGA-adjacent logic where 3.3 V operation and minimal propagation delay are critical. |
Compared with 74VHCT32PW,118, the 74VHC32PW,118 offers wider VCC range and CMOS input compatibility but fails to interface directly with TTL outputs, while SN74LVC32APWR delivers faster speed at lower voltage but sacrifices 5 V tolerance and extended temperature capability.

FAQ
Is 74VHCT32PW,118 compatible with 3.3 V microcontroller GPIOs?
No - its TTL input thresholds require minimum 2.0 V for HIGH recognition, but 3.3 V GPIOs typically output ≥2.4 V, satisfying VIH. However, output swing is 0–5 V, so level-shifting may be needed downstream if interfacing with 3.3 V receivers. Confirm VOH/VOL margins against the receiver's VIH/VIL at actual load current.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies timing up to 50 pF load capacitance. Driving >50 pF increases propagation delay nonlinearly and may cause output ringing due to trace inductance. For 100 pF loads, add a series 10–22 Ω resistor near the output pin to dampen reflections and maintain signal integrity.
Does the TSSOP14 package require thermal pad soldering?
No - the SOT402-1 package has no exposed thermal pad. Thermal dissipation relies on copper pour under pins 7 (GND) and 14 (VCC). Use ≥2 cm² internal ground plane connected via ≥4 thermal vias to inner layers to sustain 500 mW at 125 °C ambient.
Can this device be used in place of 74LS32 in existing designs?
Yes - it is pin-compatible and electrically compatible: same VCC (5 V), same input thresholds, and higher drive strength (8 mA vs. 74LS32's 0.4 mA sink). Replace with direct substitution; no layout changes needed. Verify that increased speed does not induce timing violations in legacy timing-critical paths.
