Product details
Overview
MC74VHC1G32DFT2G-L22038 from onsemi is a single 2-input OR gate IC in SC-88A (SOT-353) package, operating from 2.0 V to 5.5 V, with CMOS-level input thresholds, 3.7 ns typical propagation delay at 5 V, and over-voltage tolerant inputs/outputs up to 5.5 V-enabling robust 3 V/5 V mixed-supply interfacing in portable logic control circuits.
For engineers reviewing the MC74VHC1G32DFT2G-L22038 datasheet, pinout, applications, or equivalent options, this page delivers verified pin functions, real-world interface use cases, voltage translation capability, IOFF partial power-down support, and validated alternative options for logic-level bridging in space-constrained embedded systems.
Technical Context
This device implements standard positive-logic OR functionality (Y = A + B) using advanced VHC CMOS technology, supporting rail-to-rail input operation across its full 2.0–5.5 V supply range. Its input structure tolerates up to 5.5 V regardless of VCC, enabling safe level shifting between 3 V and 5 V domains without external components.
The output stage provides ±8 mA drive capability at 3.0 V and supports IOFF functionality-ensuring high-impedance outputs during power-down to prevent back-driving in partial-power-down systems. Propagation delays are tightly specified (e.g., 3.7 ns typ @ 5 V, CL = 15 pF), making it suitable for timing-critical signal conditioning in low-power digital subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - Enables direct integration into both 3.3 V and 5 V logic systems without level shifters. |
| tPD (Typ) | 3.7 ns at 5 V, CL = 15 pF - Supports >100 MHz toggle rates in clean-signal paths for fast control logic. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows safe connection to 5 V signals while powered from 3 V, eliminating clamping diodes. |
| IOFF Support | Yes - Outputs enter high-impedance state when VCC = 0 V, preventing current backflow in hot-swap or battery-backup scenarios. |
| Output Drive | ±8 mA at 3.0 V - Sufficient to drive multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering. |
| Operating Temp | −55 °C to +125 °C - Qualified for extended industrial and automotive under-hood applications. |
| Package | SC-88A (SOT-353), 5-pin - 2.1 mm × 1.25 mm footprint ideal for ultra-dense PCB layouts. |
Pinout & Package
SC-88A (SOT-353) package: 5-pin, 2.1 mm × 1.25 mm × 0.95 mm body, lead pitch 0.65 mm, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Standard CMOS input accepting 0–5.5 V; compatible with TTL and CMOS logic families. |
| 2 | Input A | Second OR input; identical electrical characteristics to Pin 1; no internal inversion. |
| 3 | GND | Ground reference for all I/O and internal circuitry; must be connected before VCC for ESD-safe power sequencing. |
| 4 | Output Y | Push-pull CMOS output; drives high/low actively; supports IOFF when VCC = 0 V. |
| 5 | VCC | Positive supply input; decoupling capacitor (0.1 μF) recommended within 3 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant I/O | Inputs and outputs withstand up to 5.5 V regardless of VCC - eliminates need for external protection in mixed-voltage interconnects. |
| IOFF partial power-down | Outputs go high-Z when VCC = 0 V - prevents bus contention and leakage in multi-rail systems during standby or fault conditions. |
| Low dynamic power | CPD = 8.0 pF - enables sub-μW static power at low frequencies and predictable dynamic consumption (PD = CPD·VCC²·f). |
| Wide temperature range | −55 °C to +125 °C operation - meets requirements for industrial automation, automotive body electronics, and outdoor equipment. |
| Pb-free & RoHS compliant | Halogen-free/BFR-free construction - satisfies global environmental compliance mandates without performance trade-offs. |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|
Use Scenario: Combining fault signals from multiple temperature/humidity sensors into a single alert line feeding a microcontroller interrupt pin. IC Role / Device Role / Timing Role: Logic OR gate aggregating asynchronous digital status flags with minimal propagation delay and no added latency.

IC Role / Device Role / Timing Role: Level-translating OR function accepting 5 V CC-line voltages while powered from 3.3 V system rail. Use Value: Eliminates need for dual-supply translators; 3.7 ns tPD ensures timely response to plug insertion/removal events. |
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 |
|---|---|---|---|
| SN74LVC1G32DBVR | Lower VCC min (1.65 V), higher drive (±32 mA), but max input tolerance = VCC + 0.5 V - requires external clamping above 3.6 V. | Better for ultra-low-voltage 1.8 V systems; unsuitable for direct 5 V signal interfacing without protection. | Select when operating below 2.0 V or requiring stronger drive; avoid where 5 V inputs coexist with 3 V supply. |
| 74AUP1G32GW,125 | Ultra-low power (ICC < 1 μA), slower tPD (6.4 ns @ 3.3 V), same 5.5 V input tolerance, but only rated to +85 °C. | Ideal for battery-critical wearables; not recommended for under-hood or extended-temperature industrial use. | Choose for energy-sensitive portable designs with relaxed timing; verify thermal environment fits −40 °C to +85 °C spec. |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74VHC1G32DFT2G-L22038 uniquely balances 5.5 V input tolerance, −55 °C to +125 °C operation, and 3.7 ns speed-making it optimal for ruggedized mixed-voltage control logic where reliability trumps ultra-low quiescent current.

The MC74VHC1G32DFT2G-L22038 accepts input voltages up to 5.5 V regardless of VCC level-verified per datasheet Absolute Maximum Ratings (VIN = −0.5 V to +6.5 V). This allows direct connection to 5 V signals even when powered from 2.5 V or 3.3 V, eliminating external clamping diodes in mixed-supply designs.
Does the MC74VHC1G32DFT2G-L22038 support partial power-down operation?
Yes, the MC74VHC1G32DFT2G-L22038 features IOFF circuitry that forces outputs into high-impedance state when VCC = 0 V-confirmed in DC Electrical Characteristics tables. This prevents back-driving of powered sections during hot-insertion, battery switchover, or controlled shutdown sequences.
What is the typical propagation delay of the MC74VHC1G32DFT2G-L22038 at 3.3 V?
At VCC = 3.3 V and CL = 15 pF, the MC74VHC1G32DFT2G-L22038 exhibits tPLH/tPHL = 4.8 ns (typ), per AC Electrical Characteristics table. This value increases to 7.9 ns (max) over −40 °C to +85 °C, ensuring reliable timing margin in commercial and industrial applications.
Which package does the MC74VHC1G32DFT2G-L22038 use, and what are its key dimensions?
The MC74VHC1G32DFT2G-L22038 uses the SC-88A (SOT-353) package: 5-pin, 2.1 mm × 1.25 mm × 0.95 mm body size, 0.65 mm lead pitch. Pin 1 orientation is marked by a dot or notch per onsemi mechanical drawings (Case 419A), and the device is Pb-free and RoHS-compliant.
Is the MC74VHC1G32DFT2G-L22038 suitable for automotive applications?
The base MC74VHC1G32DFT2G-L22038 is not AEC-Q100 qualified, but the pin-compatible automotive-grade variant MC74VHC1G32DFT2G-Q is explicitly qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) and PPAP-capable-per Ordering Information table and Features section.
