Product details
Overview
M74VHC1G125DFT1G-L22038 from onsemi is a single noninverting 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, tolerates inputs up to 5.5 V regardless of supply voltage, and features IOFF partial power-down protection - enabling safe interfacing between 3 V and 5 V logic domains in portable instrumentation and industrial control I/O modules.
For engineers reviewing the M74VHC1G125DFT1G-L22038 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SC-88A package mapping, confirmed 5-pin pinout with OE/A/GND/Y/VCC assignment, real-world interface use cases, and two validated alternative parts with documented electrical and application differences.
Technical Context
The M74VHC1G125DFT1G-L22038 implements a three-stage CMOS buffer architecture with a buffered 3-state output stage that ensures high noise immunity and stable signal integrity. Its input structure is overvoltage tolerant to 5.5 V independent of VCC, allowing robust 5 V-to-3 V translation without external clamping.
It incorporates IOFF circuitry that disables output leakage when VCC = 0 V, preventing back-powering of powered-down rails during hot insertion or partial system shutdown. The device uses CMOS-level input thresholds (VIH = 1.5 V @ VCC = 2.0 V; VIL = 0.5 V @ VCC = 2.0 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 operation across 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| tPD (typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - supports >100 MHz data rates in short-bus applications like sensor interface lines. |
| IOH/IOL | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - permits safe connection to 5 V sources while powered from 3.3 V, eliminating need for external diodes. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents current flow from live buses into unpowered subsystems during partial power-down. |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments. |
| ESD Rating | HBM: 2000 V - meets IEC 61000-4-2 Level 2 for board-level ESD robustness in end equipment. |
Pinout & Package
Package: SC-88A (Case 419A), 5-pin, 2.1 mm × 1.25 mm × 0.95 mm, Pb-free, RoHS-compliant surface-mount package with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable | Active-low control: pulls Y to high-impedance when high; enables noninverting pass-through of A when low. |
| 2 (A) | Data Input | CMOS-level input accepting 0–5.5 V; internally clamped and tolerant of VCC-independent overvoltage. |
| 3 (GND) | Ground Reference | Primary return path for all internal logic and output current; must be low-inductance connection for noise immunity. |
| 4 (Y) | Buffered Output | 3-state CMOS output capable of sourcing/sinking ±8 mA at 3.0 V; exhibits <0.52 V VOL at IOL = 8 mA. |
| 5 (VCC) | Supply Voltage | Power rail for internal logic and output stage; supports 2.0–5.5 V; IOFF remains active even if VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant Inputs | Accepts −0.5 V to +5.5 V regardless of VCC - eliminates external protection components when interfacing mixed-voltage subsystems. |
| IOFF Partial Power-Down | Blocks bidirectional current flow at inputs/outputs when VCC = 0 V - essential for hot-swap and battery-backup architectures. |
| Low Propagation Delay | 3.5 ns typ at 5 V enables timing-critical functions such as clock distribution enable paths and fast GPIO expansion. |
| Wide Temperature Range | Specified from −55 °C to +125 °C - suitable for deployment in industrial PLCs, motor drives, and automotive body controllers. |
| Small Footprint | SC-88A package occupies only 2.6 mm² PCB area - ideal for space-constrained portable and wearable electronics. |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|

Use Scenario: Buffering DUT control signals (e.g., reset, test mode select) in automated test fixtures where signal integrity and timing margin are critical. IC Role / Device Role / Timing Role: Low-skew, low-capacitance repeater ensuring clean edge delivery to DUT pins despite long PCB traces. Use Value: CIN = 4.0 pF and tPD = 3.5 ns minimize jitter accumulation; SC-88A footprint allows dense fixture layout near DUT. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar noninverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | TTL-compatible VIH/VIL; lower ICC (1 µA max); same SC-70-5 package but different pinout (A/GND/OE/Y/VCC). | Better suited for legacy 3.3 V-only systems with strict static current budgets; not overvoltage tolerant beyond VCC + 0.5 V. | Select when interfacing only within 3.3 V domain and ultra-low quiescent current is required; verify PCB layout compatibility due to pinout mismatch. |
| 74AUP1G125GW,125 | Lower VCC range (0.8–3.6 V); 3.8 ns tPD at 3.3 V; higher noise immunity (VNS = 0.35 × VCC); UDFN6 package (1.0 × 1.0 mm). | Optimized for ultra-low-power battery-operated devices; unsuitable for 5 V interface or industrial temperature range (>85 °C). | Choose for wearables or IoT nodes requiring sub-1 µA ICC and smallest possible footprint; avoid where 5 V tolerance or −40 °C operation is needed. |
Compared with SN74LVC1G125DBVR and 74AUP1G125GW,125, the M74VHC1G125DFT1G-L22038 uniquely combines 5.5 V input tolerance, −55 °C to +125 °C operation, and SC-88A compatibility - making it the only option among the three qualified for mixed-voltage industrial control and automotive body electronics.

FAQ
What is the function of the OE pin on the M74VHC1G125DFT1G-L22038?
The OE (Output Enable) pin on the M74VHC1G125DFT1G-L22038 is an active-low control input that places the Y output in high-impedance (tri-state) when driven high, and enables noninverting buffering of the A input when driven low. This allows dynamic bus sharing and isolation in multi-driver systems. The M74VHC1G125DFT1G-L22038 maintains IOFF protection even when OE is asserted and VCC = 0 V.
Does the M74VHC1G125DFT1G-L22038 support 5 V input signals while powered from 3.3 V?
Yes, the M74VHC1G125DFT1G-L22038 supports input voltages from −0.5 V to +5.5 V regardless of VCC level - meaning it safely accepts 5 V logic signals while operating from a 3.3 V supply. This overvoltage tolerance is built into the input structure and does not require external components. The M74VHC1G125DFT1G-L22038 is explicitly rated for this use case in its datasheet.
What is the maximum output drive capability of the M74VHC1G125DFT1G-L22038 at 3.0 V?
At VCC = 3.0 V, the M74VHC1G125DFT1G-L22038 can source or sink up to ±8 mA while maintaining VOL ≤ 0.52 V and VOH ≥ 2.34 V across the full operating temperature range (−55 °C to +125 °C). This drive strength supports fan-out to multiple 74LVC inputs or direct driving of small capacitive loads up to ~30 pF.
Is the M74VHC1G125DFT1G-L22038 qualified for automotive applications?
The base M74VHC1G125DFT1G-L22038 is not automotive-qualified; however, the pin-compatible variant M74VHC1G125DFT1G-Q (with −Q suffix) is AEC-Q100 qualified and PPAP capable. That version shares identical electrical specifications and SC-88A packaging but undergoes additional automotive-grade screening and traceability controls. The M74VHC1G125DFT1G-L22038 itself is intended for industrial and commercial applications.
What package type is used for the M74VHC1G125DFT1G-L22038?
The M74VHC1G125DFT1G-L22038 uses the SC-88A (also known as SC-70-5 or SOT-353) package: a 5-pin, gull-wing surface-mount outline measuring 2.1 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. This package is documented in Case 419A and is RoHS-compliant, Pb-free, and halogen-free.
