Product details
Overview
M74VHC1GT125DF2G-L22038 from onsemi is a single non-inverting 3-state buffer with TTL-level input thresholds, designed for level-shifting between 2.0 V and 5.5 V logic domains. 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 safe interfacing of 5 V circuits to 3 V systems in industrial control I/O modules.
For engineers reviewing the M74VHC1GT125DF2G-L22038 datasheet, pinout, applications, or equivalent options, key selection considerations include its TTL-compatible VIH/VIL thresholds (1.4 V / 0.45 V at 3.0 V), IOFF partial power-down protection, SC-88A package footprint, and guaranteed operation from −55 °C to +125 °C.
Technical Context
The M74VHC1GT125DF2G-L22038 implements a three-stage CMOS buffer architecture with a controlled 3-state output stage that ensures high noise immunity and stable signal integrity. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing robust 5 V-to-3 V bidirectional interfacing without external clamping.
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 meets AEC-Q100 Grade 1 requirements when ordered with the −Q suffix, though M74VHC1GT125DF2G-L22038 itself is a standard industrial-grade variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables direct integration into mixed-voltage systems without level translators. |
| tPD (Typ) | 3.5 ns at VCC = 5.0 V, CL = 15 pF - supports >100 MHz data rates in low-latency digital paths. |
| VIH / VIL | 1.4 V / 0.45 V at VCC = 3.0 V - TTL-compatible thresholds ensure reliable recognition of legacy 3.3 V logic outputs. |

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 | CMOS-input thresholds (VIH = 2.0 V @ 3.3 V), slightly higher ICC (max 10 µA vs. 40 µA), same SC-70-5 package. | Better suited for pure 3.3 V systems; less tolerant of 5 V inputs without external limiting. | Select when interfacing only CMOS logic and lower static current is prioritized over mixed-voltage robustness. |
| 74AUP1G125GW,125 | Ultra-low power (ICC < 0.9 µA), wider VCC range (0.8–3.6 V), but max VIO = 3.6 V - no 5.5 V over-voltage tolerance. | Optimized for battery-powered IoT nodes; incompatible with 5 V signal domains. | Choose for energy-constrained portable devices where 5 V interfacing is absent and sub-µA quiescent current is mandatory. |
