Product details
Overview
MC74VHC1G32MU3TCG from onsemi is a single 2-input OR gate in a 1.0 mm × 1.0 mm UDFN6 package with CMOS-level input thresholds, 3.7 ns propagation delay at 5 V, ±8 mA output drive at 3.0 V, and over-voltage tolerant inputs/outputs up to 5.5 V - used for level-shifting and logic interfacing between 3 V and 5 V subsystems in portable power management circuits.
For engineers reviewing the MC74VHC1G32MU3TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.0–5.5 V supply range, IOFF partial power-down support, 1.0×1.0 mm footprint, SC-70-compatible pin assignment, and AEC-Q100 qualification for automotive interface nodes.
Technical Context
This device implements a standard positive-logic OR function (Y = A + B) using advanced VHC CMOS technology. Its input structure tolerates voltages up to 5.5 V independent of VCC, enabling robust 5 V-to-3 V bidirectional interfacing without external clamping diodes.
The output stage supports active-drive capability (±8 mA at 3.0 V) and tri-state behavior during power-down via IOFF protection, which limits leakage when VCC = 0 V. The UDFN6 package features an exposed pad for thermal enhancement and includes a no-connect (NC) terminal at Pin 5 per the 1.0×1.0 mm case outline (517BX).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports mixed-voltage system integration across industrial, automotive, and portable domains. |
| tPD (Typ) | 3.7 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal routing in timing-critical control paths. |
| IOH/IOL | ±8 mA at VCC = 3.0 V - drives moderate capacitive loads (e.g., multiple CMOS inputs) without buffering. |
| VIN Tolerance | −0.5 V to +5.5 V - eliminates need for external voltage translators when interfacing legacy 5 V logic to 3 V microcontrollers. |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents back-powering and signal corruption in hot-swap or partial-power-down systems. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and extended-temperature industrial environments. |
| Package | UDFN6, 1.0 mm × 1.0 mm, 0.35 mm pitch - provides ultra-compact footprint for space-constrained PCB layouts. |
Pinout & Package
MC74VHC1G32MU3TCG uses the UDFN6 (Case 517BX) package: 1.0 mm × 1.0 mm body, 0.35 mm lead pitch, 6-terminal configuration with exposed thermal pad. Pin 1 is marked by a rotated 180° CW orientation (per ordering table), and Pin 5 is NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second OR operand; accepts CMOS-level thresholds (VIH = 1.5 V min @ VCC = 2.0 V). |
| 2 | Input A | Primary OR operand; electrically identical to Pin 1, fully over-voltage tolerant. |
| 3 | GND | Ground reference for all internal circuitry and I/O structures; must be low-impedance. |
| 4 | Output Y | OR result (Y = A + B); actively driven high/low or high-impedance when VCC = 0 V. |
| 5 | NC | No internal connection; left floating or grounded per layout best practices; not bonded. |
| 6 | VCC | Positive supply rail; powers internal logic and output stage; supports 2.0–5.5 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant I/O | Withstands −0.5 V to +5.5 V on any pin regardless of VCC - enables safe 5 V ↔ 3 V domain bridging without external protection. |
| IOFF partial power-down | Blocks current flow between powered and unpowered sections when VCC = 0 V - critical for hot-plug and battery-backup systems. |
| Ultra-small UDFN6 footprint | 1.0 mm × 1.0 mm area with 0.35 mm pitch - reduces board space by >50% vs. SC-70-5 while maintaining same pin count and function. |
| CMOS input thresholds | VIH = 70% VCC, VIL = 30% VCC - ensures noise immunity and compatibility with standard CMOS drivers across full VCC range. |
| AEC-Q100 qualified | Qualified to Grade 1 (−40 °C to +125 °C) with PPAP capability - suitable for automotive body electronics and ADAS sensor interfaces. |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |
|---|---|
Use Scenario: Combining door lock status and ignition key presence signals before enabling starter relay activation. IC Role / Device Role / Timing Role: Single OR gate performing real-time logical OR of two safety-critical digital inputs with sub-5 ns latency. Use Value: Eliminates discrete diode-OR network, reduces component count, and guarantees deterministic timing under wide temperature and voltage variation. | Use Scenario: Merging multiple sensor fault flags (e.g., temperature, pressure, flow) into a unified "system alarm" output line. IC Role / Device Role / Timing Role: Level-shifting OR gate accepting 5 V TTL sensor outputs and driving 3.3 V microcontroller interrupt input.

IC Role / Device Role / Timing Role: Low-quiescent-current OR gate operating from 2.5 V supply with IOFF protection during battery removal. Use Value: Prevents back-feeding into depleted battery; 1.0×1.0 mm size saves space in compact wearable form factors. | Use Scenario: Aggregating motion detection and ambient light trigger events to wake a Bluetooth LE microcontroller from deep sleep. IC Role / Device Role / Timing Role: Ultra-low-footprint OR gate with fast propagation (<8 ns typical) ensuring minimal wake latency. Use Value: Reduces PCB area and BOM cost versus discrete solutions while meeting strict 10 µA max ICC standby requirement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar OR 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 IOFF and only 125 °C max TJ. | Preferred for 1.8 V systems; unsuitable for hot-swap or zero-VCC isolation use cases. | Select when operating below 2.0 V or requiring tighter timing margins; verify absence of IOFF in power sequencing designs. |
| 74AUP1G32GW,125 | Wider temp range (−40 °C to +125 °C), lower ICC (0.9 µA typ), but slower tPD (10.3 ns typ @ 3.3 V) and no over-voltage tolerance. | Better for ultra-low-power always-on sensing nodes; cannot replace MC74VHC1G32MU3TCG in mixed-voltage interfaces. | Choose for battery-powered edge nodes where quiescent current dominates; avoid where 5 V signal coupling exists. |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74VHC1G32MU3TCG uniquely combines over-voltage tolerance, IOFF protection, and AEC-Q100 qualification - making it the only option among the three for automotive-grade 3 V/5 V domain bridging with fail-safe power-down behavior.

FAQ
What is the maximum input voltage rating for MC74VHC1G32MU3TCG?
The MC74VHC1G32MU3TCG supports DC input voltages from −0.5 V to +5.5 V on all pins, independent of VCC level. This over-voltage tolerance allows safe interfacing between 5 V and 3 V logic domains without external protection components, and is verified per the Absolute Maximum Ratings table in the official onsemi datasheet (Rev. 28, January 2026).
Does MC74VHC1G32MU3TCG support partial power-down operation?
Yes, MC74VHC1G32MU3TCG includes IOFF circuitry that disables input and output paths when VCC = 0 V, limiting leakage current to ≤10 µA. This feature prevents back-powering of upstream circuits and maintains signal integrity during hot insertion or battery replacement - confirmed in the DC Electrical Characteristics section for both MC74VHC1G32 and MC74VHC1GT32 variants.
What is the pin configuration for MC74VHC1G32MU3TCG's UDFN6 package?
MC74VHC1G32MU3TCG uses the UDFN6 (Case 517BX) package with Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = NC, and Pin 6 = VCC. Pin 1 orientation is rotated 180° clockwise per the ordering information table, and Pin 5 is unconnected - confirmed in the Pin Assignment (UDFN) section on page 2 of the datasheet.
Is MC74VHC1G32MU3TCG qualified for automotive applications?
Yes, MC74VHC1G32MU3TCG is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C) and PPAP capable, as indicated by the "−Q" suffix option in the ordering table and explicitly stated in the Features section. It meets automotive reliability requirements for body electronics, lighting, and sensor interface modules.
What is the typical propagation delay of MC74VHC1G32MU3TCG at 3.3 V supply?
At VCC = 3.3 V (within the 3.0–3.6 V range), the typical propagation delay (tPLH/tPHL) of MC74VHC1G32MU3TCG is 4.8 ns with CL = 15 pF, per the AC Electrical Characteristics table on page 5 of the datasheet. This value applies to both rising and falling edges and is measured under standard test conditions defined in Figure 3.
