Product details
Overview
MC74VHC1G32DFT1G-L22038 from onsemi is a single 2-input OR gate in SC-88A (SOT-353) 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-voltage interfacing in portable power management circuits.
For engineers reviewing the MC74VHC1G32DFT1G-L22038 datasheet, pinout, applications, or equivalent options, key selection considerations include input threshold compatibility (CMOS vs. TTL), IOFF partial power-down support, SC-88A footprint constraints, and guaranteed −55 °C to +125 °C operating range for industrial control logic.
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 safe level translation between 3 V and 5 V domains without external clamping.
The output stage provides symmetrical sourcing/sinking capability (±8 mA at 3.0 V), and IOFF functionality ensures high-impedance outputs when VCC = 0 V-critical for hot-swap and battery-backup systems where supply sequencing is uncontrolled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports single-supply operation across legacy 3.3 V and modern low-power 2.5 V/3.0 V rails |
| tPD (typ) | 3.7 ns at 5 V - enables timing-critical combinational logic in high-speed digital interfaces |
| IOH/IOL | ±8 mA at 3.0 V - drives standard CMOS loads and small LED indicators directly |
| VIN Tolerance | −0.5 V to +5.5 V - eliminates need for external protection diodes when interfacing to 5 V peripherals |
| IOFF Support | Active at VCC = 0 V - prevents back-driving powered subsystems during partial power-down |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial motor-control environments |
| ESD Rating | 2000 V HBM - withstands handling in non-ESD-controlled assembly lines |
Pinout & Package
MC74VHC1G32DFT1G-L22038 uses the SC-88A (SOT-353) 5-pin surface-mount package (3.00 mm × 1.50 mm × 0.95 mm), optimized for space-constrained PCB layouts in portable electronics and sensor nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second OR operand; accepts CMOS-level signals up to 5.5 V regardless of VCC |
| 2 | Input A | Primary OR operand; identical electrical characteristics to Pin 1 |
| 3 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance connection |
| 4 | Output Y | OR result (Y = A + B); actively driven high/low with ±8 mA capability at 3.0 V |
| 5 | VCC | Positive supply rail; powers internal logic and enables IOFF behavior when at 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Over-voltage tolerant I/O | Inputs and outputs withstand −0.5 V to +5.5 V - eliminates external protection components in mixed-voltage systems |
| IOFF partial power-down | Outputs enter high-impedance state when VCC = 0 V - prevents current leakage during system sleep modes |
| Wide VCC range | Operates from 2.0 V to 5.5 V - compatible with Li-ion battery discharge curves and multi-rail PMIC outputs |
| Low propagation delay | 3.7 ns typical at 5 V - meets timing budgets in fast clock-domain crossing and status aggregation circuits |
| AEC-Q100 qualification | Qualified per AEC-Q100 Rev G Grade 1 - suitable for automotive body electronics and infotainment subsystems |

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 speed (3.5 ns typ at 3.3 V), but no 5.5 V input tolerance | Suitable for pure 1.8 V/3.3 V systems; not recommended for 5 V interface scenarios | Select when operating exclusively below 3.6 V and maximum speed is prioritized over voltage flexibility |
| 74AUP1G32GW,125 | Ultra-low power (ICC = 0.9 μA typ), wider temp range (−40 °C to +125 °C), but only 3.6 V max VCC | Better for always-on battery-powered nodes; lacks 5 V tolerance and automotive qualification | Prefer for energy-harvesting or coin-cell devices where quiescent current dominates design trade-offs |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, MC74VHC1G32DFT1G-L22038 uniquely balances 5.5 V input tolerance, AEC-Q100 qualification, and −55 °C low-temp operation-making it the only choice for industrial-grade mixed-voltage control logic requiring extended environmental resilience.

FAQ
What logic family does MC74VHC1G32DFT1G-L22038 belong to, and how does it differ from TTL or LVC variants?
MC74VHC1G32DFT1G-L22038 belongs to the VHC (Very High Speed CMOS) logic family. Unlike TTL, it uses CMOS-level input thresholds (VIH = 1.5 V at 2.0 V VCC) and offers rail-to-rail output swing. Compared to LVC variants, MC74VHC1G32DFT1G-L22038 supports higher input voltage tolerance (up to 5.5 V) and operates down to −55 °C-features not found in standard LVC gates like SN74LVC1G32.
Does MC74VHC1G32DFT1G-L22038 support hot insertion or partial power-down scenarios?
Yes, MC74VHC1G32DFT1G-L22038 supports partial power-down via its IOFF feature: when VCC = 0 V, outputs automatically enter high-impedance state, preventing back-current flow from live inputs or outputs. This makes MC74VHC1G32DFT1G-L22038 suitable for hot-plug modules and battery-backed systems where supply sequencing is uncontrolled.
What is the maximum input voltage MC74VHC1G32DFT1G-L22038 can tolerate, and does it depend on VCC?
MC74VHC1G32DFT1G-L22038 tolerates input voltages from −0.5 V to +5.5 V regardless of VCC value. This independence allows safe interfacing between 5 V sensors and 3 V microcontrollers without level shifters. The absolute maximum rating remains fixed even when VCC is 2.0 V or 0 V-confirmed in the datasheet's Maximum Ratings table.
Is MC74VHC1G32DFT1G-L22038 qualified for automotive applications?
Yes, MC74VHC1G32DFT1G-L22038 is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C) and PPAP capable. The "−Q" suffix variant (e.g., MC74VHC1G32DFT1G−Q) is explicitly designated for automotive use, but the base part number MC74VHC1G32DFT1G-L22038 shares identical qualification and manufacturing controls per onsemi's documentation.
What package type is used for MC74VHC1G32DFT1G-L22038, and are there pin-compatible alternatives in other footprints?
MC74VHC1G32DFT1G-L22038 uses the SC-88A (SOT-353) 5-pin package. onsemi offers pin-compatible versions in SC-74A (MC74VHC1G32DBVT1G), SOT-953 (MC74VHC1G32P5T5G), and UDFN6 (MC74VHC1G32MU1TCG/MU2TCG/MU3TCG), all sharing identical logic function and electrical specs-but differing in pinout order and thermal performance due to package geometry.
