Product details
Overview
74VHC32BQ,115 from Nexperia is a quad 2-input OR gate IC in DHVQFN14 package, operating at 2.0–5.5 V supply with CMOS input levels, 7 ns typical propagation delay (VCC = 4.5–5.5 V, CL = 15 pF), and rated for -40 °C to +125 °C ambient. It delivers balanced timing performance and Schmitt-trigger inputs for noise immunity in digital logic interfacing, bus arbitration, and control signal combining.
For engineers reviewing the 74VHC32BQ,115 datasheet, 74VHC32BQ,115 pinout, 74VHC32BQ,115 application, or 74VHC32BQ,115 equivalent, this device serves as a high-speed, temperature-robust OR logic element compatible with LSTTL-level systems via its 74VHCT32BQ counterpart - critical for industrial control, sensor interface aggregation, and FPGA/CPLD glue logic design.
Technical Context
This device implements four independent 2-input OR gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC standard No. 7-A and pin-compatible with LSTTL. Its Schmitt-trigger inputs accept voltages exceeding VCC and provide hysteresis for reliable signal conditioning in noisy environments.
The logic function follows standard Boolean OR behavior: output is HIGH if at least one input is HIGH; LOW only when both inputs are LOW. Input thresholds are CMOS-level (VIH ≥ 3.85 V at VCC = 5.5 V; VIL ≤ 1.65 V), ensuring clean switching across full rail-to-rail operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - provides four independent OR operations per package, enabling compact logic consolidation. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports dual-voltage system interoperability (e.g., 3.3 V microcontrollers interfacing with 5 V peripherals). |
| Propagation Delay | 2.8 ns (typ) at VCC = 4.5–5.5 V, CL = 15 pF - enables sub-10 ns timing-critical paths in high-speed digital control loops. |
| Input Thresholds | VIH = 3.85 V min, VIL = 1.65 V max at VCC = 5.5 V - ensures robust noise margin (>1.3 V) against ground bounce or crosstalk. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range embedded controllers. |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift. |
| Power Dissipation | 500 mW max at Tamb ≤ 125 °C - thermal derating of 9.6 mW/K above 98 °C enables stable operation in thermally constrained QFN layouts. |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, exposed thermal pad (non-soldered by default; may be floated or grounded), 14 terminals, terminal 1 index area marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts CMOS-level signals; Schmitt-triggered for noise rejection. |
| 2 | 1B | First OR gate input B - paired with 1A; identical electrical characteristics and timing. |
| 3 | 1Y | First OR gate output - drives up to 8 mA sink/source; TTL-compatible output swing. |
| 4 | 2A | Second OR gate input A - electrically isolated from other gates; same VIH/VIL specs. |
| 5 | 2B | Second OR gate input B - supports independent logic combination without fanout constraints. |
| 6 | 2Y | Second OR gate output - matches 1Y drive strength and voltage levels. |
| 7 | GND | Ground reference (0 V) - must be low-impedance; shared return for all four gates. |
| 8 | 3Y | Third OR gate output - routed to adjacent terminal for minimal trace length in dense PCB layouts. |
| 9 | 3A | Third OR gate input A - positioned to minimize crosstalk between input/output pairs. |
| 10 | 3B | Third OR gate input B - symmetrical with 3A; supports identical timing and loading. |
| 11 | 4Y | Fourth OR gate output - final output terminal; completes functional set of four OR functions. |
| 12 | 4A | Fourth OR gate input A - placed opposite VCC for balanced power distribution. |
| 13 | 4B | Fourth OR gate input B - complements 4A; enables full utilization of quad-gate resource. |
| 14 | VCC | Positive supply rail - decoupling capacitor required within 1 cm for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides hysteresis (≈0.3–0.5 V) on all 8 inputs, rejecting sub-microsecond noise spikes common in industrial wiring. |
| CMOS input level compatibility | Accepts VI up to 7.0 V regardless of VCC - enables level-shifting and hot-swap tolerant interface design. |
| Balanced propagation delays | tPLH and tPHL match within ±0.3 ns (typ), eliminating skew-induced glitches in synchronous logic trees. |
| Thermally enhanced QFN | DHVQFN14 package offers 2× lower θJA vs SO14 - improves reliability in sealed enclosures with limited airflow. |
| Wide temperature qualification | Specified over -40 °C to +125 °C with full static/dynamic parameter validation - eliminates derating assumptions. |
Applications
| Industrial Control Logic | Microcontroller Peripheral Interface |
|---|---|

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 |
|---|---|---|---|
| 74VHCT32BQ,115 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout and package; slightly higher tpd (3.1 ns typ @ CL=15 pF). | Required when interfacing legacy 5 V TTL logic or microcontrollers with non-rail-referenced outputs. | Select when input sources lack CMOS-level drive capability but require same thermal and footprint advantages. |
| SN74LVC32APWR | Lower VCC range (1.65–3.6 V); LVCMOS inputs; 3.5 ns tpd @ 3.3 V; TSSOP14 package (SOT402-1). | Suitable only for 3.3 V-only systems; incompatible with 5 V tolerant operation or industrial temperature range. | Choose only for cost-sensitive, single-rail 3.3 V designs where -40 °C to +125 °C rating is not required. |
Compared with 74VHC32BQ,115, the 74VHCT32BQ,115 trades minor speed for broader input compatibility, while SN74LVC32APWR sacrifices voltage flexibility and temperature range for lower static current - making the original part optimal for mixed-voltage, high-reliability applications.

FAQ
Is the exposed thermal pad on the DHVQFN14 package required to be soldered?
No. Per Nexperia's datasheet, the exposed pad (terminal 1 index area) has no electrical or mechanical requirement to be soldered. If connected, it must remain floating or tied to GND - never to VCC or signal nets. This preserves thermal performance without introducing unintended parasitic coupling.
Can 74VHC32BQ,115 safely interface with 5 V TTL outputs?
Yes - but only through the 74VHCT32BQ,115 variant. The 74VHC32BQ,115 uses CMOS input thresholds (VIH ≥ 3.85 V at VCC = 5.5 V), which exceed standard TTL VOH (2.4 V). For true TTL compatibility, use the pin-identical 74VHCT32BQ,115, whose VIH is specified at 2.0 V min.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF (per output) with guaranteed timing and voltage margins. Driving >50 pF increases propagation delay nonlinearly and risks output overshoot; for loads >60 pF, add a series resistor (22–47 Ω) near the output to dampen ringing and maintain signal integrity.
Does this part support partial power-down or I/O isolation when VCC = 0 V?
No. The datasheet specifies IIK (input clamping current) and IOK (output clamping current) limits but does not guarantee I/O high-impedance state during VCC = 0 V. Inputs remain active and may draw current; outputs can source/sink up to ±20 mA. Always power VCC before applying signals.
