Product details
Overview
MC74VHC1GT32P5T5G-L22088 from onsemi is a single 2-input OR gate in SOT-953 package, designed for 2.0 V to 5.5 V operation with TTL-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 control circuits.
For engineers reviewing the MC74VHC1GT32P5T5G-L22088 datasheet, pinout, applications, or equivalent options, key selection considerations include its TTL-compatible VIH/VIL thresholds (1.4 V/0.45 V at 3.0 V), IOFF partial power-down protection, and SOT-953 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements standard positive-logic OR functionality (Y = A + B) using advanced VHC CMOS technology. Its TTL-level input thresholds enable direct interfacing with legacy 5 V TTL outputs while operating from a 3 V supply, eliminating level-shifter requirements in mixed-voltage systems.
The input and output structures tolerate voltages up to 5.5 V regardless of VCC, and IOFF circuitry ensures high-impedance outputs during power-down-critical for hot-swap and battery-backup applications where supply sequencing is uncontrolled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports wide supply flexibility across industrial, automotive, and portable systems |
| tPD (typ) | 3.7 ns at 5 V - enables high-speed signal routing in timing-critical logic paths |
| VIH / VIL | 1.4 V / 0.45 V at 3.0 V - TTL-compatible thresholds ensure reliable recognition of 5 V logic levels |
| IOUT | ±8 mA at 3.0 V - sufficient drive strength for fan-out to multiple CMOS/TTL loads |
| Input/Output Tolerance | Up to 5.5 V - allows safe interfacing between 3 V and 5 V domains without external clamping |
| IOFF Support | Yes - prevents back-driving and current leakage when VCC = 0 V, essential for partial power-down |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and under-hood automotive environments |
Pinout & Package
SOT-953 (5-pin, 1.0 mm × 0.8 mm × 0.37 mm, 0.35 mm pitch) with exposed pad not present; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First OR input - accepts TTL-level signals up to 5.5 V independent of VCC |
| 2 | GND | Ground reference - must be connected to system ground plane for noise immunity and proper logic threshold definition |
| 3 | B | Second OR input - electrically identical to Pin 1; both inputs support over-voltage tolerance |
| 4 | Y | OR output - drives CMOS/TTL loads with 8 mA sink/source capability at 3.0 V |
| 5 | VCC | Positive supply - powers internal logic; IOFF remains active even if VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Enables direct connection to legacy 5 V TTL outputs without level shifters in 3 V systems |
| Over-voltage tolerant I/O | Withstands 5.5 V on any pin regardless of VCC - eliminates need for external protection diodes |
| IOFF partial power-down | Maintains high-impedance outputs when VCC = 0 V - prevents bus contention during hot insertion or backup switching |
| Low propagation delay | 3.7 ns typical at 5 V - supports >100 MHz toggle rates in combinatorial logic paths |
| Pb-free, RoHS-compliant | Meets global environmental regulations and reflow soldering standards (JEDEC J-STD-020) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | CMOS-level inputs (VIH = 2.1 V at 3.3 V); slightly higher tPD (4.5 ns typ) | Requires level-shifting for 5 V TTL inputs; better suited for pure 3.3 V systems | Select when interfacing exclusively with 3.3 V CMOS sources and lower static power is prioritized |
| 74AUP1G32GW,125 | Lower VCC range (0.8–3.6 V); ultra-low ICC (0.9 μA max); smaller XSON-6 package | Not 5 V tolerant; unsuitable for mixed 3 V/5 V interfaces | Choose for battery-powered sub-3 V designs where size and standby current are critical |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, MC74VHC1GT32P5T5G-L22088 uniquely balances TTL-level compatibility, 5.5 V over-voltage tolerance, and SOT-953 compactness-making it the only option among the three that safely bridges 3 V logic and legacy 5 V signal sources without external components.

FAQ
What is the input voltage threshold behavior of MC74VHC1GT32P5T5G-L22088?
The MC74VHC1GT32P5T5G-L22088 features TTL-level input thresholds: VIH = 1.4 V and VIL = 0.45 V at VCC = 3.0 V. This allows reliable recognition of standard 5 V TTL output levels while operating from a 3 V supply-eliminating the need for external level-shifting circuitry in mixed-voltage designs.
Does MC74VHC1GT32P5T5G-L22088 support partial power-down operation?
Yes, MC74VHC1GT32P5T5G-L22088 includes IOFF circuitry that places outputs in high-impedance state when VCC = 0 V. This prevents back-driving and current leakage during hot insertion or battery-backup scenarios-ensuring system integrity when power rails are sequenced independently.
What is the maximum propagation delay for MC74VHC1GT32P5T5G-L22088 across its full operating range?
The maximum propagation delay for MC74VHC1GT32P5T5G-L22088 is 11.5 ns at VCC = 3.0–3.6 V and CL = 15 pF over the full temperature range (−55 °C to +125 °C). At 5 V, the max tPD is 8.0 ns under the same load and temperature conditions.
Can MC74VHC1GT32P5T5G-L22088 safely interface a 5 V sensor output to a 3.3 V microcontroller input?
Yes, MC74VHC1GT32P5T5G-L22088 can safely interface a 5 V sensor output to a 3.3 V microcontroller input. Its inputs tolerate up to 5.5 V regardless of VCC, and its TTL-level thresholds ensure correct logic interpretation. The output swings rail-to-rail (0 V to 3.3 V), matching the MCU's input voltage requirements.
Is MC74VHC1GT32P5T5G-L22088 qualified for automotive applications?
MC74VHC1GT32P5T5G-L22088 itself is not AEC-Q100 qualified; however, the MC74VHC1GT32DFT2G−Q* variant (same die, SC-88A package) is AEC-Q100 qualified and PPAP capable. For automotive use, specify the −Q suffix version-MC74VHC1GT32P5T5G-L22088 is intended for industrial and commercial applications with extended temperature support (−55 °C to +125 °C).
