Product details
Overview
MC74VHC1G32P5T5G from onsemi is a single 2-input OR gate in SOT-953 package, designed for 2.0 V to 5.5 V operation with CMOS-level input thresholds. It delivers 3.7 ns typical propagation delay at 5 V, supports 8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V-enabling robust 3 V/5 V mixed-supply interfacing in portable power management circuits.
For engineers reviewing the MC74VHC1G32P5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its SOT-953 footprint, IOFF partial power-down support, ±25 mA output current capability, and AEC-Q100 qualification readiness via −Q variants.
Technical Context
This device implements standard positive-logic OR functionality (Y = A + B) using advanced VHC CMOS technology. Its input structure tolerates voltages up to 5.5 V independent of VCC, enabling safe level-shifting between 3 V and 5 V domains without external components.
The output stage supports tri-state behavior under power-down conditions via IOFF protection, and exhibits low dynamic power consumption with CPD = 8.0 pF. Propagation delay varies predictably with supply voltage and load capacitance-e.g., 4.4 ns typical at 5 V with 50 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply systems and battery-powered designs with wide input tolerance. |
| tPD (Typ) | 3.7 ns at 5 V, CL = 15 pF - enables high-speed logic interfacing in timing-critical signal paths. |
| IOH/IOL | ±8 mA at 3.0 V - sufficient to drive multiple 74-series inputs or small LEDs directly. |
| VIN/VOUT Tolerance | Up to 5.5 V - eliminates need for external clamping diodes when interfacing 5 V signals to 3 V logic. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents back-powering and ensures clean shutdown in partial-power-down architectures. |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments. |
| ESD Rating | HBM: 2000 V - provides robust handling during PCB assembly and field service. |
Pinout & Package
SOT-953 (CASE 527AE), 5-pin ultra-small surface-mount package measuring 1.00 mm × 0.80 mm × 0.37 mm with 0.35 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First OR input; accepts CMOS-level thresholds (VIH = 1.5 V min at 2 V VCC). |
| 2 | GND | Ground reference for logic and power; required for stable bias and noise immunity. |
| 3 | B | Second OR input; electrically identical to Pin 1 with same input threshold specs. |
| 4 | Y | OR output; actively drives high/low states and enters high-impedance when VCC = 0 V (IOFF active). |
| 5 | VCC | Positive supply rail; powers internal circuitry and defines logic threshold levels. |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant I/O | Withstands 5.5 V on inputs/outputs regardless of VCC - enables direct 5 V-to-3 V interface without level shifters. |
| IOFF partial power-down | Output goes high-Z when VCC = 0 V - prevents current backflow and bus contention in hot-swap or sleep-mode systems. |
| Low propagation delay | 3.7 ns typical at 5 V - meets timing budgets in fast control loops and data path gating. |
| High output drive | 8 mA sink/source at 3.0 V - reduces need for buffer stages when driving capacitive loads or fan-out > 10. |
| Pb-free & RoHS compliant | Meets global environmental regulations and reflow soldering standards (JEDEC J-STD-020). |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |

IC Role / Device Role / Timing Role: Low-quiescent-current OR combiner feeding interrupt input of ultra-low-power microcontroller. Use Value: ICC ≤ 40 µA max at 5.5 V minimizes standby drain; SOT-953 footprint saves space on compact PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | Lower VCC min (1.65 V), higher speed (3.5 ns typ @ 3.3 V), but no 5.5 V I/O tolerance. | Preferred for 1.8 V/3.3 V-only systems; unsuitable for 5 V interfacing without external protection. | Select when operating exclusively below 3.6 V and maximum speed is critical. |
| 74AUP1G32GW,125 | Ultra-low power (ICC < 1 µA), wider temp range (−40 °C to +125 °C), but only 3.6 V max VCC and no 5.5 V tolerance. | Better for battery life in always-on IoT nodes; lacks mixed-voltage robustness of MC74VHC1G32P5T5G. | Choose for energy-constrained applications where 5 V compatibility is unnecessary. |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74VHC1G32P5T5G uniquely balances 5.5 V I/O tolerance, −55 °C to +125 °C operation, and SOT-953 size-making it optimal for ruggedized mixed-supply industrial and automotive edge nodes.

FAQ
What is the logic function implemented by the MC74VHC1G32P5T5G?
The MC74VHC1G32P5T5G implements a standard 2-input positive-logic OR gate (Y = A + B). Its truth table shows output Y is HIGH when either input A or B (or both) is HIGH, and LOW only when both inputs are LOW. This function is verified across the full operating range of 2.0 V to 5.5 V VCC and −55 °C to +125 °C ambient temperature per the official onsemi datasheet.
Does the MC74VHC1G32P5T5G support level shifting between 3 V and 5 V systems?
Yes, the MC74VHC1G32P5T5G supports bidirectional level shifting: its inputs and outputs tolerate up to 5.5 V regardless of VCC value. When powered at 3.0 V, it safely accepts 5 V input signals and drives 5 V–compatible loads, eliminating external level translators. This capability is explicitly specified in the Absolute Maximum Ratings and DC Electrical Characteristics sections of the MC74VHC1G32P5T5G datasheet.
What is the maximum output current rating for the MC74VHC1G32P5T5G?
The MC74VHC1G32P5T5G is rated for ±25 mA DC output current per IOUT in the Absolute Maximum Ratings table. Under recommended operating conditions, it delivers ±8 mA at 3.0 V while maintaining VOH ≥ 2.48 V and VOL ≤ 0.44 V-verified across −40 °C to +85 °C. These values are measured with defined test conditions and appear in the DC Electrical Characteristics table for MC74VHC1G32P5T5G.
Is the MC74VHC1G32P5T5G suitable for automotive applications?
The base MC74VHC1G32P5T5G is not AEC-Q100 qualified, but onsemi offers automotive-grade variants with −Q suffix (e.g., MC74VHC1G32P5T5G−Q) that are AEC-Q100 qualified and PPAP capable. These versions share identical electrical specifications and SOT-953 packaging, differing only in traceability, screening, and change control-making MC74VHC1G32P5T5G a direct drop-in option for automotive designs when ordered with the −Q suffix.
What package type does the MC74VHC1G32P5T5G use, and what are its dimensions?
The MC74VHC1G32P5T5G uses the SOT-953 package (CASE 527AE), a 5-pin ultra-compact surface-mount outline measuring 1.00 mm × 0.80 mm × 0.37 mm with 0.35 mm lead pitch. Pin 1 marking is "F", and the package is Pb-free and RoHS compliant-confirmed in the Ordering Information section of the MC74VHC1G32P5T5G datasheet.
