Product details
Overview
MC74VHC1G125P5T5G-L22088 from onsemi is a single non-inverting 3-state buffer IC designed for level-shifting and bus isolation in low-voltage digital systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns propagation delay at 5 V (typ), supports ±8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V - enabling safe interfacing between 3 V and 5 V logic domains in portable instrumentation and industrial control I/O modules.
For engineers reviewing the MC74VHC1G125P5T5G-L22088 datasheet, pinout, applications, or equivalent options, key selection considerations include its CMOS-level input thresholds, IOFF partial power-down protection, SC-953 package footprint, and guaranteed operation across −55 °C to +125 °C.
Technical Context
The MC74VHC1G125P5T5G-L22088 implements a three-stage buffered architecture with a high-noise-immunity 3-state output stage. Its input structure tolerates voltages up to 5.5 V independent of VCC, supporting mixed-supply interface applications without external clamping diodes.
IOFF circuitry actively disables input/output paths when VCC = 0 V, preventing back-powering and current leakage during partial power-down states - critical for hot-swap and battery-backed subsystems. The device uses standard CMOS-level VIH/VIL thresholds (e.g., VIH = 3.15 V min at VCC = 4.5 V), distinguishing it from the TTL-threshold MC74VHC1GT125 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables direct use in both 3.3 V and 5 V systems without level translators. |
| tPD (typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - ensures timing compatibility with high-speed microcontroller GPIOs and FPGA I/O banks. |
| IOH/IOL | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or small LED indicators without external buffers. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - allows safe connection to 5 V signals while powered from 3 V, eliminating risk of latch-up or damage. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents unintended current flow into powered downstream circuits during standby or shutdown. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and outdoor telecom equipment. |
| Package | SOT-953 (1.0 mm × 0.8 mm, 0.35 mm pitch) - ultra-compact footprint ideal for space-constrained PCB layouts. |
Pinout & Package
SOT-953 package: 5-pin, 1.0 mm × 0.8 mm body, 0.35 mm pitch, exposed pad optional per design. Pin 1 marked by dot or bevelled edge; top-view orientation follows JEDEC MO-252.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Buffer Input | Non-inverting data input; accepts CMOS-level logic (VIH ≥ 3.15 V @ 4.5 V VCC). |
| 2 (GND) | Ground Reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 3 (OE) | Output Enable Control | Active-low 3-state enable; drives Y high-impedance when high, regardless of A state. |
| 4 (Y) | Buffer Output | Non-inverted, 3-state output; sinks or sources up to 8 mA at 3.0 V with rail-to-rail swing. |
| 5 (VCC) | Power Supply | Positive supply input; decoupling capacitor (0.1 µF) required within 2 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand −0.5 V to +5.5 V regardless of VCC - eliminates need for external protection in mixed-voltage interconnects. |
| IOFF Partial Power-Down | Blocks current flow between input/output pins when VCC = 0 V - essential for hot-plug interfaces and battery backup circuits. |
| Low Propagation Delay | 3.5 ns typical at 5 V enables use in 100+ MHz clock distribution and fast data gating without timing bottlenecks. |
| Wide Temperature Range | Specified from −55 °C to +125 °C - supports deployment in automotive engine control units and industrial motor drives. |
| Pb-Free & RoHS Compliant | Meets J-STD-609 Class 3 moisture sensitivity (MSL 1) and UL 94 V-0 flammability rating - suitable for reflow soldering and safety-critical designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | TTL-compatible input thresholds (VIH = 2.0 V min @ 3.3 V); slightly higher ICC (max 10 µA vs. 40 µA for MC74VHC1G125). | Better suited for interfacing with older 3.3 V logic families requiring lower VIH; less robust for 5 V-tolerant operation. | Select when interfacing with legacy LVTTL or mixed 3.3 V/2.5 V systems where strict 5 V tolerance is not required. |
| 74AUP1G125GW,125 | Lower VCC range (0.8 V–3.6 V); 3.8 ns tPD at 3.3 V; IOFF support but no 5.5 V over-voltage tolerance. | Optimized for ultra-low-power battery-operated devices; incompatible with 5 V signal domains. | Prefer for sub-1 µA standby current in wearables or IoT sensors - only if system stays strictly ≤3.6 V. |
Compared with SN74LVC1G125DBVR and 74AUP1G125GW,125, the MC74VHC1G125P5T5G-L22088 uniquely balances 5.5 V I/O tolerance, −55 °C to +125 °C operation, and 3.5 ns speed - making it the sole choice for ruggedized mixed-voltage industrial and automotive bus isolation.

FAQ
What is the maximum input voltage the MC74VHC1G125P5T5G-L22088 can tolerate?
The MC74VHC1G125P5T5G-L22088 supports DC input voltages from −0.5 V to +5.5 V, independent of VCC level. This over-voltage tolerance allows safe connection to 5 V signals even when powered from 2.0–3.3 V supplies - a key feature confirmed in the Absolute Maximum Ratings table (VIN = −0.5 to +6.5 V) and functional description of input protection structures.
Does the MC74VHC1G125P5T5G-L22088 support partial power-down operation?
Yes, the MC74VHC1G125P5T5G-L22088 includes IOFF circuitry that disables input and output paths when VCC = 0 V. Per the datasheet, IOFF leakage is limited to ≤10 µA under this condition, preventing back-current flow and protecting downstream circuits during hot insertion or battery-backup scenarios.
What is the propagation delay of the MC74VHC1G125P5T5G-L22088 at 3.3 V supply?
At VCC = 3.3 V and CL = 15 pF, the MC74VHC1G125P5T5G-L22088 exhibits a typical propagation delay (tPLH/tPHL) of 4.5 ns, with a maximum of 9.5 ns over the full operating temperature range (−55 °C to +125 °C). These values are specified in the AC Electrical Characteristics table for VCC = 3.0–3.6 V.
Which package type does the MC74VHC1G125P5T5G-L22088 use?
The MC74VHC1G125P5T5G-L22088 uses the SOT-953 package (Case 527AE), a 5-pin surface-mount outline measuring 1.0 mm × 0.8 mm with 0.35 mm pitch. This is explicitly listed in the Ordering Information table and confirmed by the "P5" suffix in the part number.
Is the MC74VHC1G125P5T5G-L22088 qualified for automotive applications?
The base MC74VHC1G125P5T5G-L22088 is not AEC-Q100 qualified; however, onsemi offers automotive-grade variants with "−Q" suffix (e.g., MC74VHC1G125DFT2G−Q). The datasheet confirms that −Q parts meet AEC-Q100 Grade 1 requirements and PPAP capability - the standard version lacks this qualification.
