Product details
Overview
MC74VHC1G32P5T5G-L22088 from onsemi is a single 2-input OR gate in SOT-953 package, operating from 2.0 V to 5.5 V supply, 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 - used for level-shifting logic interfaces between 3 V and 5 V subsystems in portable instrumentation.
For engineers reviewing the MC74VHC1G32P5T5G-L22088 datasheet, pinout, applications, or equivalent options, key selection considerations include input threshold compatibility (CMOS vs TTL), IOFF partial power-down support, 8 mA drive capability at 3.0 V, and SOT-953 footprint constraints for space-constrained PCB layouts.
Technical Context
This device implements a standard positive-logic OR function (Y = A + B) using advanced VHC CMOS technology. Its input structure supports 5.5 V tolerance independent of VCC, enabling safe interfacing between mixed-supply domains without external clamping.
The output stage provides ±8 mA drive at 3.0 V and features IOFF circuitry that disables I/O paths when VCC = 0 V, preventing back-powering and bus contention during hot insertion or partial power-down sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V logic systems without level translators. |
| tPD (typ) | 3.7 ns at 5 V, CL = 15 pF - enables high-speed signal routing in timing-critical control paths. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - allows connection to 5 V signals while powered from 3 V, eliminating need for external protection diodes. |
| IOFF Support | Active when VCC = 0 V - prevents current leakage through I/O pins during system sleep or power sequencing. |
| IOH/IOL | ±8 mA at 3.0 V - sufficient to drive multiple 74LVC inputs or small LED indicators directly. |
| Operating Temp | −55 °C to +125 °C - qualified for industrial and extended-temperature embedded applications. |
| ESD Rating | HBM: 2000 V - meets basic handling robustness requirements for automated assembly environments. |
Pinout & Package
SOT-953 (5-pin, 1.0 mm × 0.8 mm, 0.35 mm pitch) - ultra-compact surface-mount package optimized for high-density portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First OR input - accepts CMOS-level logic signals; tolerant to 5.5 V regardless of VCC. |
| 2 | GND | Ground reference - must be connected to system ground plane for stable noise margin and ESD path. |
| 3 | B | Second OR input - electrically identical to Pin 1; supports same voltage tolerance and threshold behavior. |
| 4 | Y | OR output - actively drives high/low states; tri-state not supported; IOFF active only during VCC = 0. |
| 5 | VCC | Positive supply - powers internal logic; IOFF protection engages automatically if this pin is unpowered. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0–5.5 V operation eliminates need for separate voltage regulators in multi-rail systems. |
| Over-voltage tolerant I/O | Inputs and outputs withstand 5.5 V even at 2.0 V VCC - enables seamless 5 V-to-3 V interface without external components. |
| IOFF partial power-down | Prevents current flow through I/O pins when VCC = 0 - critical for hot-plug and battery-backup circuits. |
| Low propagation delay | 3.7 ns (5 V, 15 pF) ensures minimal timing skew in synchronous control logic chains. |
| Pb-free & RoHS compliant | Meets global environmental compliance requirements for industrial and consumer electronics manufacturing. |

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 | TTL-compatible input thresholds (VIH = 2.0 V min @ 3.3 V); slightly higher ICC (10 µA max vs 1.0 µA). | Better suited for legacy 3.3 V systems with marginal VIH margins; less tolerant of 5 V inputs without clamping. | Select when interfacing with older LVTTL peripherals where input threshold alignment is critical. |
| NC7SZ32P5X | Smaller UDFN-6 (1.0 × 1.0 mm) package; identical VHC-family specs but no IOFF support. | Lacks power-down isolation - unsuitable for hot-swap or battery-backed subsystems requiring VCC-off safety. | Choose for ultra-miniature designs where IOFF is not required and board space is more constrained than functional safety. |
Compared with SN74LVC1G32DBVR and NC7SZ32P5X, MC74VHC1G32P5T5G-L22088 uniquely combines 5.5 V input tolerance, IOFF, and SOT-953 compactness - making it optimal for mixed-voltage portable systems needing robust power sequencing.

FAQ
What is the input threshold type of MC74VHC1G32P5T5G-L22088?
The MC74VHC1G32P5T5G-L22088 uses CMOS-level input thresholds: VIH = 1.5 V (min) at 2.0 V VCC, scaling to 3.85 V at 5.5 V VCC. This distinguishes it from the MC74VHC1GT32 variant, which has TTL-level thresholds. The CMOS thresholds ensure compatibility with modern low-voltage microcontrollers and reduce static power consumption in high-impedance states.
Does MC74VHC1G32P5T5G-L22088 support tri-state output?
No, MC74VHC1G32P5T5G-L22088 does not support tri-state output. It is a standard push-pull OR gate with active-high and active-low output drive only. The device does feature IOFF (power-off isolation), which disables I/O paths when VCC = 0 V - but this is not equivalent to programmable output enable or high-impedance control.
Can MC74VHC1G32P5T5G-L22088 safely interface a 5 V signal to a 3 V microcontroller?
Yes, MC74VHC1G32P5T5G-L22088 can safely interface a 5 V signal to a 3 V microcontroller: its inputs tolerate up to 5.5 V regardless of VCC, and its outputs swing rail-to-rail (0 V to VCC). When powered from 3.3 V, it accepts 5 V inputs without damage and produces 3.3 V–compatible logic levels - eliminating external level-shifting components.
What is the maximum output drive strength of MC74VHC1G32P5T5G-L22088 at 3.0 V?
At 3.0 V VCC, MC74VHC1G32P5T5G-L22088 delivers ±8 mA output drive (IOH = −8 mA, IOL = +8 mA) under DC conditions. This is sufficient to drive up to 10 LVC-series inputs or a small indicator LED with appropriate current limiting, supporting direct integration into resource-constrained embedded nodes without buffer amplification.
Is MC74VHC1G32P5T5G-L22088 qualified for automotive applications?
MC74VHC1G32P5T5G-L22088 itself is not automotive-qualified; however, the MC74VHC1G32DFT2G−Q variant (same die, SC-88A package) is AEC-Q100 qualified and PPAP capable. The P5T5G suffix indicates SOT-953 packaging and commercial-grade qualification - suitable for industrial and consumer applications, but not certified for automotive under hood or safety-critical use cases.
