Product details
Overview
MC74VHC1G50P5T5G-L22088 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 features 3.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and over-voltage tolerant inputs/outputs up to 5.5 V - enabling robust 3 V/5 V mixed-voltage interfacing in portable and industrial control circuits.
For engineers reviewing the MC74VHC1G50P5T5G-L22088 datasheet, pinout, applications, or equivalent options, key selection considerations include its SOT-953 package footprint, IOFF partial power-down support, TTL-incompatible CMOS input thresholds, and guaranteed operation across −55 °C to +125 °C.
Technical Context
This device implements a non-inverting buffer with Schmitt-trigger-free CMOS input structure optimized for low-noise digital signal routing. Its input stage tolerates up to 5.5 V regardless of VCC, supporting hot-swap and battery-backup scenarios where supply sequencing is uncontrolled.
The output stage provides symmetrical sourcing/sinking capability (±8 mA at 3.0 V) and includes IOFF circuitry that disables I/O leakage when VCC = 0 V - critical for system-level power gating and multi-rail isolation in embedded controllers and sensor hubs.
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 microcontroller I/O rails and legacy 5 V logic subsystems. |
| tPD (Typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - enables timing-critical signal buffering in high-speed serial interface paths (e.g., UART, SPI clock lines). |
| IOFF Support | Active at VCC = 0 V - prevents back-driving and leakage current during partial power-down, simplifying power-state management in battery-powered devices. |
| Input Voltage Tolerance | −0.5 V to +5.5 V independent of VCC - eliminates need for external clamping diodes when interfacing 5 V sensors to 3 V hosts. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to directly drive multiple 74LVC inputs or small LED indicators without external buffers. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O cards, and outdoor telecom equipment. |
| ESD Rating | HBM: 2000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD robustness in end-user accessible ports. |
Pinout & Package
SOT-953 (Case 527AE), 1.00 mm × 0.80 mm × 0.37 mm, 5-pin ultra-small surface-mount package with exposed pad option not specified; pin 1 marked by dot or bevelled edge per JEDEC MO-252.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A | CMOS-compatible digital input; accepts 0–5.5 V regardless of VCC; no internal pull-up/down. |
| 2 | GND | Primary ground reference for all internal circuitry and I/O structures; must be connected before VCC for safe power-up. |
| 3 | NC | No internal connection; electrically isolated; may be left floating or tied to GND for mechanical stability. |
| 4 | Output Y | Non-inverting buffered output; drives rail-to-rail CMOS levels; supports tri-state behavior only in variants with OE pin (not this part). |
| 5 | VCC | Positive supply input; powers internal logic and output stage; must be decoupled locally with ≥0.1 µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand −0.5 V to +5.5 V regardless of VCC state - enables safe 5 V-to-3 V translation without level shifters. |
| IOFF Partial Power-Down | Input/output leakage drops to ≤10 µA when VCC = 0 V - preserves isolation between powered and unpowered subsystems in modular designs. |
| Low Propagation Delay | 3.5 ns typical at 5 V allows use in 100+ MHz clock distribution paths with minimal skew accumulation. |
| Pb-Free & RoHS Compliant | Meets EU RoHS Directive 2011/65/EU and halogen-free/BFR-free requirements - suitable for consumer, medical, and industrial end-equipment. |
| Wide Temperature Range | Specified from −55 °C to +125 °C - validated for deployment in engine control units, motor drives, and base station RF front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Tri-state output enabled via OE pin; 3.3 V only VCC range (1.65–5.5 V); 3.7 ns tPD at 3.3 V. | Requires explicit OE control logic; unsuitable for always-on buffering without additional GPIO. | Select when bidirectional bus isolation or dynamic output disabling is required. |
| 74LVC1G07GW,125 | Open-drain output; no internal pull-up; 3.2 ns tPD at 3.3 V; same SOT-353 package. | Cannot source current; requires external pull-up for high-level assertion; incompatible with push-pull loads. | Select only for wired-OR logic, I²C bus extension, or active-low enable signaling. |
Compared with SN74LVC1G125DBVR and 74LVC1G07GW,125, the MC74VHC1G50P5T5G-L22088 offers fixed non-inverting push-pull drive with superior 5.5 V overvoltage tolerance and broader VCC range - making it optimal for permanent signal path conditioning where simplicity, robustness, and mixed-voltage interoperability are prioritized over tri-state flexibility or open-drain compatibility.

FAQ
What is the input threshold voltage specification for MC74VHC1G50P5T5G-L22088?
The MC74VHC1G50P5T5G-L22088 uses CMOS-level input thresholds: VIH = 0.7×VCC (min) and VIL = 0.3×VCC (max) - for example, at VCC = 3.3 V, VIH ≥ 2.31 V and VIL ≤ 0.99 V. This differs from TTL-compatible variants like MC74VHC1GT50, which have fixed VIH/VIL thresholds independent of VCC. These values are fully characterized across −55 °C to +125 °C per the official onsemi datasheet revision 23.
Does MC74VHC1G50P5T5G-L22088 support tri-state operation?
No, MC74VHC1G50P5T5G-L22088 does not support tri-state operation. It is a fixed-function non-inverting buffer with no output-enable (OE) pin. Tri-state capability is available only in related parts such as MC74VHC1G125 (single buffer with OE) or MC74VHC1G126 (single bus buffer with OE). The MC74VHC1G50P5T5G-L22088 output remains active whenever VCC is applied and is not controllable via external logic.
Can MC74VHC1G50P5T5G-L22088 be used to interface 5 V logic to a 1.8 V microcontroller?
MC74VHC1G50P5T5G-L22088 can accept 5 V inputs safely due to its 5.5 V overvoltage-tolerant inputs, but its output swing is rail-to-rail relative to its own VCC - so with VCC = 1.8 V, the high-level output is ~1.8 V, which may fall below the VIH requirement of many 1.8 V logic families. For reliable 5 V-to-1.8 V translation, a dedicated level shifter (e.g., TXB0102) or a VCC = 3.3 V configuration with downstream logic compatible with 3.3 V outputs is recommended. The MC74VHC1G50P5T5G-L22088 itself is not a bidirectional level translator.
What is the thermal resistance (θJA) of MC74VHC1G50P5T5G-L22088 in its SOT-953 package?
The thermal resistance θJA for MC74VHC1G50P5T5G-L22088 in the SOT-953 package (Case 527AE) is 254 °C/W, measured on a standard FR-4 board with minimum pad spacing and no airflow per JESD51-7. This value assumes a 10 mm × 25.4 mm (1 inch) 2-ounce copper trace. Actual board layout - especially thermal vias under the exposed pad (if present) - can reduce θJA significantly; however, the SOT-953 variant of MC74VHC1G50P5T5G-L22088 does not include an exposed thermal pad per the official package drawings.
Is MC74VHC1G50P5T5G-L22088 qualified for automotive applications?
MC74VHC1G50P5T5G-L22088 itself is not AEC-Q100 qualified. Automotive-qualified versions exist under different part numbers - for example, MC74VHC1GT50DFT1G-Q (SC-88A) and MC74VHC1GT50DBVT1G-Q (SC-74A) carry the "-Q" suffix and are explicitly listed as AEC-Q100 qualified and PPAP capable. The MC74VHC1G50P5T5G-L22088 is intended for industrial and commercial applications, with full characterization across −55 °C to +125 °C but without automotive-specific stress testing or documentation.
