Product details
Overview
MC74VHC32DR2G-Q from onsemi is a quad 2-input OR gate IC in SOIC-14 package, operating from 2.0 V to 5.5 V, with 3.8 ns typical propagation delay at 5.0 V, ±8 mA output drive, and AEC-Q100 qualification for automotive use.
For engineers reviewing the MC74VHC32DR2G-Q datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 terminal mapping, automotive-grade interface behavior, and direct logic-family alternatives.
Technical Context
The MC74VHC32DR2G-Q implements four independent OR logic functions (Y = A + B) using silicon-gate CMOS technology, achieving TTL-compatible speed while maintaining CMOS power efficiency. Its three-stage internal architecture includes a buffered output stage for high noise immunity and stable switching.
Input structures tolerate up to 5.5 V, enabling safe interfacing between 3.3 V and 5.0 V systems; output swings fully rail-to-rail (0 V to VCC) under all valid supply conditions. The −Q suffix denotes AEC-Q100 qualification, PPAP capability, and controlled manufacturing site requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate (Y = A + B), fully independent channels |
| Propagation Delay | 3.8 ns typical at VCC = 5.0 V, CL = 15 pF - enables >100 MHz toggle rates in clean signal paths |
| Supply Range | 2.0 V to 5.5 V - supports mixed-voltage system interfacing without level shifters |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive standard CMOS loads and small capacitive buses |
| Input Voltage Tolerance | −0.5 V to 5.5 V - allows hot-insertion and 5 V-tolerant inputs in 3 V systems |
| Quiescent Current | 2.0 µA max at TA = 25°C - ensures ultra-low static power in battery-backed or standby circuits |
| Operating Temperature | −55°C to +125°C - meets extended automotive ambient requirements |
Pinout & Package
MC74VHC32DR2G-Q is housed in a 14-lead SOIC (Small Outline Integrated Circuit) package per case 751A, with 1.27 mm pitch, Pb-free finish, and JEDEC-standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | First input of Gate 1 - accepts CMOS-level signals (VIH ≥ 1.5 V @ VCC = 2.0 V) |
| 2 | B1 | Second input of Gate 1 - electrically identical to Pin 1; both inputs tolerant to 5.5 V |
| 3 | Y1 | Output of Gate 1 - rail-to-rail CMOS output swing (0 V to VCC), ±8 mA drive capability |
| 4 | A2 | First input of Gate 2 - shares same voltage tolerance and logic threshold as Pins 1 and 2 |
| 5 | B2 | Second input of Gate 2 - no internal connection to other gates; fully isolated function |
| 6 | Y2 | Output of Gate 2 - independently buffered; immune to crosstalk from Y1/Y3/Y4 |
| 7 | GND | Ground reference - must be low-impedance return path for all four gates' output currents |
| 8 | Y3 | Output of Gate 3 - matches Y1/Y2/Y4 in timing, drive strength, and noise rejection |
| 9 | A3 | First input of Gate 3 - pin-compatible with A1/A2/A4; no shared internal nodes |
| 10 | B3 | Second input of Gate 3 - supports same VIH/VIL thresholds across full VCC range |
| 11 | Y4 | Output of Gate 4 - final output; identical AC/DC specs to Y1–Y3 |
| 12 | A4 | First input of Gate 4 - electrically decoupled from other inputs; no internal fan-in sharing |
| 13 | B4 | Second input of Gate 4 - completes fourth OR function; supports 5.5 V tolerant operation |
| 14 | VCC | Positive supply - powers all four gates; bypass capacitor (0.1 µF) required near this pin |
Key Features
| Feature | Design Value |
|---|---|
| High-speed CMOS logic | 3.8 ns tPD at 5 V enables use in 100+ MHz clock domains and fast control-path decision logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC32DR2G | No −Q suffix; commercial temperature range (−40°C to +85°C); same electrical specs and pinout | Not AEC-Q100 qualified; unsuitable for automotive production or safety-critical industrial use | Select when cost sensitivity outweighs automotive qualification requirements and ambient stays ≤85°C |
| SN74LVC32APWR | TSSOP-14 package; 1.65–3.6 V supply only; 3.9 ns tPD at 3.3 V; lower drive (±24 mA) | Optimized for 3.3 V systems; lacks 5.5 V input tolerance and extended temperature support | Prefer for space-constrained 3.3 V designs where 5 V interfacing is unnecessary and AEC-Q100 not mandated |
Compared with MC74VHC32DR2G-Q, the MC74VHC32DR2G offers identical performance at lower cost but lacks automotive qualification, while SN74LVC32APWR trades voltage flexibility and qualification for smaller size and higher drive in 3.3 V-only contexts.

FAQ
What is the maximum input voltage rating for MC74VHC32DR2G-Q?
The MC74VHC32DR2G-Q supports DC input voltages from −0.5 V to +5.5 V, independent of VCC. This 5.5 V tolerance allows safe interfacing with 5 V logic sources even when powered from 3.3 V or 2.5 V supplies, eliminating external clamping diodes in mixed-voltage designs.
Is MC74VHC32DR2G-Q pin-compatible with standard TTL OR gates?
MC74VHC32DR2G-Q is functionally and pin-compatible with 74LS32 and 74F32, but uses CMOS input thresholds (VIH ≥ 70% VCC). It is not TTL-input compatible like the MC74VHCT32A variant; for true TTL-level input acceptance, MC74VHCT32ADR2G−Q is the qualified automotive alternative.
Does MC74VHC32DR2G-Q support partial power-down operation?
Yes - MC74VHC32DR2G-Q features power-down protection on all inputs. When VCC = 0 V, inputs remain high-impedance and tolerate −0.5 V to +5.5 V, preventing back-powering or latch-up during hot-swap or battery-backup scenarios common in automotive gateway modules.
What is the thermal resistance (θJA) of the SOIC-14 package used by MC74VHC32DR2G-Q?
The SOIC-14 package (case 751A) for MC74VHC32DR2G-Q has a junction-to-ambient thermal resistance (θJA) of 116°C/W when mounted on a standard FR-4 PCB with minimum copper pad spacing and no airflow, per JESD51-7. This value assumes 2-ounce copper traces on a 76 mm × 114 mm board.
Can MC74VHC32DR2G-Q drive a 50 pF load at 50 MHz without signal degradation?
At VCC = 5.0 V and CL = 50 pF, MC74VHC32DR2G-Q exhibits 6.5 ns max propagation delay and 0.8 V max dynamic VOL (VOLP), confirming clean switching into 50 pF loads at frequencies up to 50 MHz. Layout best practices (short traces, ground plane, local decoupling) are required to maintain integrity.
