Product details
Overview
MC74VHC1G32MU1TCG from onsemi is a single 2-input OR gate in a UDFN6 (1.45 × 1.0 mm, 0.5 mm pitch) 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 logic systems.
For engineers reviewing the MC74VHC1G32MU1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN6 footprint compatibility, IOFF partial power-down protection, −55 °C to +125 °C operating range, and AEC-Q100 qualification suitability for automotive signal conditioning and industrial control logic.
Technical Context
The MC74VHC1G32MU1TCG implements standard positive-logic OR functionality (Y = A + B) using advanced CMOS process technology. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe level translation between 3 V and 5 V domains without external components.
It includes IOFF circuitry that disables outputs and isolates I/O pins when VCC = 0 V, preventing back-driving and bus contention during partial power-down sequences. The device exhibits low quiescent current (≤40 µA at 5.5 V) and supports hot insertion in powered-backplane applications.
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 subsystems without level shifters. |
| tPD (Typ) | 3.7 ns at 5 V, CL = 15 pF - supports high-speed timing-critical combinational logic paths in microcontroller peripherals. |
| IOH/IOL | ±8 mA at 3.0 V - sufficient to directly drive multiple 74LVC inputs or small LED indicators without buffering. |
| VIN Tolerance | −0.5 V to +5.5 V - eliminates need for external clamping diodes when interfacing to 5 V signals while powered from 3 V. |
| IOFF Support | Active at VCC = 0 V - prevents current leakage and data corruption during system sleep or hot-swap events. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial temperature-grade deployments. |
| ESD Rating | HBM: 2000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD robustness. |
Pinout & Package
MC74VHC1G32MU1TCG uses a 6-pin UDFN package (1.45 mm × 1.0 mm, 0.5 mm pitch) with exposed thermal pad. Pin 1 is marked by a dot rotated 90° clockwise; pin 6 is VCC. The NC pin (Pin 5) must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second OR operand; accepts CMOS-level thresholds (VIH ≥ 1.5 V @ 2 V, ≥ 3.85 V @ 5.5 V). |
| 2 | Input A | Primary OR operand; electrically identical to Pin 1 with same voltage threshold behavior. |
| 3 | GND | Ground reference for all internal logic and I/O; requires low-impedance PCB connection for noise immunity. |
| 4 | Output Y | OR result (Y = A + B); rail-to-rail swing with VOL ≤ 0.1 V @ 4 mA, VOH ≥ 4.4 V @ 5.5 V. |
| 5 | NC | No connect - must be left floating; not internally bonded or used in any functional mode. |
| 6 | VCC | Positive supply; decoupling capacitor (0.1 µF ceramic) required within 2 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand up to 5.5 V regardless of VCC - enables safe 5 V signal injection into 3 V systems without damage. |
| IOFF Partial Power-Down | Outputs enter high-impedance state with <10 µA leakage when VCC = 0 V - critical for PCIe-style hot-plug and battery-backed subsystems. |
| Wide Temperature Range | Specified from −55 °C to +125 °C - supports deployment in engine control units, motor drives, and outdoor industrial controllers. |
| Low Dynamic Power | CPD = 8.0 pF - limits no-load switching power to <0.2 mW at 10 MHz and 5 V, reducing thermal load in dense logic arrays. |
| Pb-Free & RoHS Compliant | Meets J-STD-609 Class 1 moisture sensitivity and UL 94 V-0 flammability - suitable for lead-free reflow and global environmental compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | Same 5-pin SOT-23-5 package; TTL-compatible VIH/VIL thresholds; 3.2 ns tPD at 3.3 V. | Lacks IOFF and over-voltage tolerance; limited to 3.6 V max VCC. | Prefer for cost-sensitive 3.3 V-only designs where partial power-down is unnecessary. |
| 74AUP1G32GW,125 | UDFN6 (1.0 × 1.0 mm); lower ICC (0.9 µA), higher tPD (12.4 ns typ at 3.3 V); supports 0.8–3.6 V. | Not AEC-Q100 qualified; unsuitable for automotive under-hood use. | Choose for ultra-low-power battery-operated IoT edge nodes requiring sub-1 µA static current. |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74VHC1G32MU1TCG uniquely combines AEC-Q100 qualification, 5.5 V over-voltage tolerance, and IOFF in a miniature UDFN6 footprint - making it the only option among the three qualified for mixed-voltage automotive body electronics with hot-swap capability.

FAQ
What is the maximum input voltage rating for MC74VHC1G32MU1TCG?
The MC74VHC1G32MU1TCG supports DC input voltages from −0.5 V to +5.5 V, independent of VCC level. This over-voltage tolerance allows safe connection of 5 V signals even when the device is powered from 2.0 V or 3.3 V, eliminating external protection components in mixed-supply systems. Absolute maximum VIN is +6.5 V per the datasheet's Maximum Ratings table.
Does MC74VHC1G32MU1TCG support partial power-down operation?
Yes, MC74VHC1G32MU1TCG includes IOFF circuitry that actively disables outputs and isolates I/O pins when VCC = 0 V. This feature prevents back-driving, bus contention, and current leakage during hot-insertion or system sleep modes. Measured IOFF leakage is ≤10 µA at 5.5 V input or output voltage, ensuring robust partial power-down behavior in complex power-sequenced systems.
What is the pin configuration and marking for MC74VHC1G32MU1TCG?
MC74VHC1G32MU1TCG uses a 6-pin UDFN package (1.45 × 1.0 mm, 0.5 mm pitch) with pin 1 identified by a dot rotated 90° clockwise. Pinout is: 1=B, 2=A, 3=GND, 4=Y, 5=NC, 6=VCC. The "MU1" in the part number denotes the 1.45 × 1.0 mm UDFN variant; marking on the top surface includes a 3-character code followed by date code "M".
Is MC74VHC1G32MU1TCG qualified for automotive applications?
Yes, MC74VHC1G32MU1TCG is AEC-Q100 qualified and PPAP capable. It meets Grade 1 requirements (−40 °C to +125 °C) and includes design features such as latch-up immunity (>100 mA), enhanced ESD robustness (2000 V HBM), and controlled moisture sensitivity (MSL Level 1). The "−Q" suffix variants (e.g., MC74VHC1G32DFT1G−Q) are explicitly designated for automotive use, but the base MC74VHC1G32MU1TCG shares the same qualification.
What logic family does MC74VHC1G32MU1TCG belong to, and how does it differ from VHC1GT32?
MC74VHC1G32MU1TCG belongs to the VHC (Very High Speed CMOS) logic family and implements CMOS-level input thresholds (VIH ≥ 70% VCC, VIL ≤ 30% VCC). In contrast, the MC74VHC1GT32 variant uses TTL-compatible thresholds (VIH ≈ 2.0 V fixed, VIL ≈ 0.8 V fixed), making it suitable for interfacing with legacy 5 V TTL outputs. Both share identical output drive, timing, and packaging options - only input threshold behavior differs.
