Product details

Overview

M74VHC1G125DFT2G-L22038 from onsemi is a single noninverting 3-state buffer IC designed for level-shifting and bus isolation in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns propagation delay at 5 V (typ), supports ±8 mA drive at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V - enabling reliable interfacing between 3 V and 5 V logic domains in portable instrumentation and industrial control modules.

For engineers reviewing the M74VHC1G125DFT2G-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, IOFF partial power-down support, and two validated alternative parts for voltage-level translation use cases.

Technical Context

The M74VHC1G125DFT2G-L22038 implements a three-stage CMOS architecture with buffered 3-state output, delivering high noise immunity and stable switching behavior. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe 5 V-to-3 V bidirectional interfacing without external clamping.

It includes IOFF circuitry that disables I/O leakage when VCC = 0 V, supporting hot-insertion and partial power-down modes. The device uses CMOS-level input thresholds (VIH = 1.5 V @ 2.0 V VCC; VIL = 0.5 V @ 2.0 V VCC) and is distinct from the TTL-threshold MC74VHC1GT125 variant.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 5.5 V - enables operation across 2.5 V, 3.3 V, and 5 V supply rails without level shifters.
tPD (typ)	3.5 ns at VCC = 5 V, CL = 15 pF - supports >100 MHz data rates in low-latency digital paths.
IOH/IOL	±8 mA at VCC = 3.0 V - drives standard 50 Ω transmission lines or multiple 74-series inputs.
Input Voltage Tolerance	−0.5 V to +5.5 V - permits direct connection to 5 V sources while powered from 3 V, eliminating external protection diodes.
IOFF Leakage	≤10 µA at VCC = 0 V - prevents back-powering of inactive sections during partial system shutdown.
Operating Temp	−55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments.
ESD Rating	HBM: 2000 V - withstands handling in uncontrolled assembly environments without additional ESD safeguards.

Pinout & Package

Package: SC-88A (Case 419A), 5-pin, 2.0 mm × 1.25 mm × 0.95 mm, lead pitch 0.65 mm, Pb-free, RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	OE (Output Enable)	Active-low control: pulls Y to high-impedance when high; enables noninverting pass-through when low.
2	A (Input)	CMOS-level digital input; accepts 0–5.5 V regardless of VCC, enabling mixed-supply signal routing.
3	GND	Ground reference for all internal logic and I/O structures; must be connected before VCC for robust ESD performance.
4	Y (Output)	3-state buffered output; exhibits <0.1 V VOL and >2.9 V VOH at 3.0 V VCC with 8 mA load.
5	VCC	Positive supply rail; powers internal logic and output stage; IOFF protection active when VCC = 0 V.

Key Features

Feature	Design Value
Overvoltage-tolerant I/O	Inputs and outputs withstand −0.5 V to +5.5 V independent of VCC - eliminates need for external voltage clamps in 3 V/5 V interface designs.
IOFF partial power-down	Blocks current flow between A/Y and GND/VCC when VCC = 0 V - prevents backfeeding and ensures safe hot-swap operation.
Low propagation delay	3.5 ns typical at 5 V enables timing-critical applications such as clock distribution buffers and fast serial bus isolators.
Wide temperature range	Specified from −55 °C to +125 °C - supports deployment in industrial motor drives and automotive body control modules.
Small-footprint packaging	SC-88A (2.0 × 1.25 mm) reduces PCB area by >50% vs. SOIC-5 - ideal for space-constrained portable and wearable electronics.

FAQ

What is the function of the OE pin on the M74VHC1G125DFT2G-L22038?

The OE (Output Enable) pin on the M74VHC1G125DFT2G-L22038 is an active-low control input that places the Y output in high-impedance (tri-state) mode when driven high, and enables noninverting signal pass-through from A to Y when driven low. This allows multiple devices to share a common bus without contention, and is essential for implementing dynamic signal routing in systems like test fixtures or modular sensor hubs.

Does the M74VHC1G125DFT2G-L22038 support 5 V to 3.3 V level translation?

Yes, the M74VHC1G125DFT2G-L22038 supports bidirectional 5 V to 3.3 V level translation. Its inputs and outputs tolerate up to 5.5 V regardless of VCC, so it can accept 5 V logic signals while powered from 3.3 V, and drive 5 V-tolerant receivers from a 3.3 V supply. This eliminates external resistive dividers or dedicated level translators in mixed-voltage designs.

Is the M74VHC1G125DFT2G-L22038 qualified for automotive applications?

The base M74VHC1G125DFT2G-L22038 is not automotive-qualified, but the pin-compatible M74VHC1G125DFT2G-Q variant is AEC-Q100 Grade 1 qualified and PPAP capable. For automotive body control or infotainment modules requiring qualification, engineers should specify the -Q suffix version; the -L22038 suffix denotes a specific tape-and-reel packaging configuration, not a qualification grade.

What is the maximum capacitive load the M74VHC1G125DFT2G-L22038 can drive reliably?

The M74VHC1G125DFT2G-L22038 is characterized for CL = 15 pF and CL = 50 pF loads in its AC electrical specifications. At VCC = 5 V, tPLH/tPHL increases from 3.5 ns (15 pF) to 4.5 ns (50 pF), confirming stable operation up to 50 pF. Driving heavier loads may degrade edge rate and increase propagation delay beyond datasheet limits, so layout parasitics and downstream input capacitance must be included in total CL budgeting.

How does the IOFF feature of the M74VHC1G125DFT2G-L22038 improve system reliability?

The IOFF (power-off protection) feature of the M74VHC1G125DFT2G-L22038 disables I/O leakage paths when VCC = 0 V, limiting current to ≤10 µA. This prevents back-powering of powered-down subsystems - critical during hot insertion, partial power-down states, or battery backup scenarios. In systems like modular PLCs or field-replaceable sensor cards, IOFF ensures isolated sections remain electrically inert without requiring mechanical interlocks or auxiliary power gating.
