Product details
Overview
MC74VHC1G50P5T5G from onsemi is a single CMOS buffer IC with CMOS-level input thresholds, designed for level-shifting and signal conditioning in 2.0 V to 5.5 V systems. It delivers 3.5 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 and industrial control applications.
For engineers reviewing the MC74VHC1G50P5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include its SOT-953 package footprint, IOFF partial power-down capability, rail-to-rail input tolerance, and guaranteed operation across −55 °C to +125 °C.
Technical Context
This device implements a non-inverting buffer topology with ESD-protected CMOS input stages and push-pull output drivers. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe interfacing between 5 V legacy circuits and 3 V logic domains without external level shifters.
The output stage supports active-drive (±8 mA at 3.0 V) and high-impedance tri-state behavior when enabled via IOFF functionality during partial power-down. Thermal resistance is 254 °C/W (SOT-953), supporting stable operation under continuous load in compact PCB layouts.
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 supply rails without voltage translation. |
| tPD (Typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - supports high-speed signal buffering in timing-critical paths like clock distribution or data lines. |
| IOH/IOL | ±8 mA at VCC = 3.0 V - sufficient to drive multiple standard CMOS loads or small capacitive traces without external buffers. |
| Input Tolerance | −0.5 V to +5.5 V regardless of VCC - eliminates risk of latch-up or damage when interfacing mismatched voltage domains. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents back-powering and ensures clean isolation during system sleep or hot-swap events. |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood, industrial motor control, and extended-temperature embedded systems. |
| Package | SOT-953 (1.00 mm × 0.80 mm, 0.35 mm pitch) - ultra-compact footprint ideal for space-constrained portable and wearable designs. |
Pinout & Package
SOT-953 package: 5-pin, 1.00 mm × 0.80 mm body, 0.35 mm pitch, exposed pad not present. Pin 1 marked by dot or beveled edge; top-view orientation per Figure 2 in datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A (Input) | CMOS-compatible non-inverting data input; accepts 0–5.5 V regardless of VCC. |
| 2 | GND | Ground reference for all internal circuitry and output return path. |
| 3 | NC | No internal connection; must be left unconnected or tied to GND for mechanical stability. |
| 4 | Y (Output) | Push-pull buffered output; actively drives high/low or enters high-Z state when VCC = 0 V (IOFF). |
| 5 | VCC | Positive supply rail; powers internal logic and output stage; range 2.0–5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand −0.5 V to +5.5 V independent of VCC - enables safe 5 V → 3 V interface without external clamping. |
| IOFF Partial Power-Down | Outputs enter high-impedance state with ≤10 µA leakage when VCC = 0 V - prevents back-driving during hot insertion or power sequencing. |
| Wide Supply Range | Operates from 2.0 V to 5.5 V - supports battery-powered devices (2.5–3.6 V) and legacy 5 V systems on same BOM. |
| Low Propagation Delay | 3.5 ns typical tPLH/tPHL at 5 V - maintains signal integrity in high-frequency digital paths up to ~100 MHz. |
| Pb-Free & RoHS Compliant | Meets JESD22-A114 (MSL Level 1), UL 94 V-0 flammability, and halogen-free/BFR-free requirements - suitable for consumer and industrial end-equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | TTL-compatible Schmitt-trigger input; no over-voltage tolerance beyond VCC + 0.5 V. | Limited to single-supply domain use; unsuitable for 5 V → 3.3 V interfacing without external protection. | Select when hysteresis is required for noisy signal conditioning, but avoid where cross-voltage domain safety is critical. |
| 74LVC1G07GW,125 | Open-drain output; requires external pull-up; no IOFF or over-voltage tolerance. | Only supports active-low drive; cannot source current or operate as true bidirectional level shifter. | Choose only for wired-OR bus applications or where open-drain logic is explicitly required. |
Compared with SN74LVC1G17DBVR and 74LVC1G07GW,125, the MC74VHC1G50P5T5G uniquely combines rail-independent input tolerance, push-pull drive, and IOFF isolation - making it the sole option among the three for fail-safe mixed-voltage buffering without auxiliary components.

FAQ
What is the maximum input voltage rating for MC74VHC1G50P5T5G?
The MC74VHC1G50P5T5G supports DC input voltages from −0.5 V to +5.5 V, independent of the VCC supply voltage. This over-voltage tolerance allows safe connection to 5 V sources even when operating from a 3.3 V or 2.5 V rail, eliminating risk of damage during voltage-domain interfacing. The specification is validated across −55 °C to +125 °C.
Does MC74VHC1G50P5T5G support tri-state operation?
The MC74VHC1G50P5T5G does not include an explicit output-enable control pin and therefore does not provide user-controllable tri-state functionality. However, its IOFF feature automatically places the output in a high-impedance state when VCC = 0 V, providing passive isolation during power-down or hot-swap conditions - a key distinction from standard tri-state buffers.
What is the thermal resistance (θJA) of MC74VHC1G50P5T5G in its SOT-953 package?
The MC74VHC1G50P5T5G in SOT-953 has a junction-to-ambient thermal resistance (θJA) of 254 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value enables reliable operation at full rated output current (±8 mA) up to +125 °C ambient when mounted with standard solder reflow profiles.
Can MC74VHC1G50P5T5G be used to interface 5 V logic to a 1.8 V microcontroller?
The MC74VHC1G50P5T5G is not recommended for direct 5 V → 1.8 V interfacing because its minimum VCC is 2.0 V, and output VOH at 2.0 V is only 1.9 V (min), which may not meet 1.8 V system VIH requirements. For 1.8 V systems, use MC74VHC1G50 variants rated down to 1.65 V or select a dedicated 5 V-to-1.8 V level shifter.
Is MC74VHC1G50P5T5G pin-compatible with other packages in the same family?
No - the MC74VHC1G50P5T5G uses the SOT-953 package with unique pin 1 orientation (top-view: Pin 1 = A, Pin 2 = GND, Pin 3 = NC, Pin 4 = Y, Pin 5 = VCC), differing from SC-88A, SC-74A, and UDFN6 variants. Substituting packages requires PCB layout revision due to distinct pin assignments and footprint dimensions.
