Product details

Overview

M74VHC1G135DFT1G-L22038 from onsemi is a single 2-input Schmitt-trigger NAND gate with open-drain output, designed for level-shifting and noise-immune signal conditioning in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 4.9 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 industrial control I/O modules.

For engineers reviewing the M74VHC1G135DFT1G-L22038 datasheet, pinout, applications, or equivalent options, this device is selected for robust input hysteresis (0.3–2.25 V), IOFF partial power-down protection, and SC-74A package compatibility in space-constrained PCB layouts requiring ESD-hardened digital signal conditioning.

Technical Context

The M74VHC1G135DFT1G-L22038 implements a three-stage CMOS architecture with buffered output stage and Schmitt-trigger input hysteresis, delivering stable switching thresholds (VT+ = 2.2–3.85 V, VT− = 0.9–1.65 V) across −55 °C to +125 °C. Its open-drain output supports wired-AND configurations and external pull-up flexibility, while IOFF circuitry prevents back-current flow when VCC = 0 V.

Input structures tolerate 5.5 V regardless of VCC, allowing safe 5 V signal injection into 3 V-powered systems. The device achieves TTL-compatible speed (tPD ≤ 10.3 ns at 5 V, CL = 50 pF) with CMOS-level quiescent current (ICC ≤ 40 µA max), making it suitable for low-power, high-noise environments such as factory automation sensor interfaces.

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 supply domains without level translators.
tPD (5 V, CL = 15 pF)	4.9 ns (typ) - ensures fast response in real-time digital control loops with minimal timing uncertainty.
Input Hysteresis (VH)	0.30–2.25 V - suppresses chatter on slow-rising or noisy signals like mechanical switch inputs or analog sensor outputs.
IOL / IOS (3.0 V)	±8 mA - drives standard LED indicators or small MOSFET gates directly without external buffers.
IOFF Leakage	≤10 µA at VCC = 0 V - prevents unintended current paths during hot-swap or partial power-down sequences.
ESD Rating (HBM)	2000 V - meets industrial IEC 61000-4-2 system-level immunity requirements without added protection diodes.
Operating Temp	−55 °C to +125 °C - qualified for under-hood automotive sensors and outdoor telecom equipment.

Pinout & Package

Package: SC-74A (Case 318BQ), 5-pin surface-mount, 3.00 mm × 1.50 mm × 0.95 mm body, 0.95 mm pitch, RoHS-compliant, Pb-free.

Pin/Terminal	Circuit Role	Design Meaning
1	Input B	Active-low Schmitt-trigger input; accepts 0–5.5 V independent of VCC for mixed-voltage interfacing.
2	Input A	Active-low Schmitt-trigger input; identical electrical behavior to Pin 1, enabling dual-signal conditioning.
3	GND	Ground reference for all internal logic and output discharge path; must be low-impedance for noise immunity.
4	Output Y	Open-drain output; requires external pull-up to define high state voltage and logic level - supports wired-AND bus topologies.
5	VCC	Positive supply rail; powers internal logic and defines input threshold ranges; IOFF active when VCC = 0 V.

Key Features

Feature	Design Value
Overvoltage-Tolerant Inputs	Withstands 5.5 V input signals at any VCC (2.0–5.5 V), eliminating need for external clamping in 5 V-to-3 V interface circuits.
IOFF Partial Power-Down	Blocks current flow through inputs/outputs when VCC = 0 V, preventing backfeeding and enabling safe hot-insertion in modular systems.
Wide Temperature Range	Guaranteed operation from −55 °C to +125 °C - validated for engine control units and industrial PLC I/O cards.
Low Input Capacitance	CIN ≤ 10 pF - minimizes loading on high-impedance sources such as RC-filtered sensor outputs or long PCB traces.
Open-Drain Output Flexibility	Allows configurable pull-up voltage (e.g., 1.8 V, 3.3 V, or 5 V) and multi-source wired-AND logic - ideal for interrupt bus sharing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G135DBVR	Lower VCC range (1.65–5.5 V); 3.5 ns tPD at 3.3 V; no IOFF; 1000 V HBM ESD rating.	Lacks partial power-down protection and reduced ESD margin - unsuitable for hot-swap or high-reliability medical use.	Select when cost and speed at 3.3 V are prioritized over robustness in mixed-voltage or safety-critical systems.
74AUP1G135GW,125	Ultra-low power (ICC ≤ 0.9 µA); wider temp range (−40 to +125 °C); 5.2 ns tPD at 3.3 V; no overvoltage tolerance.	Inputs limited to VCC + 0.3 V - requires external clamping for 5 V signal interfacing, increasing design complexity.	Prefer for battery-powered portable devices where quiescent current dominates over interface flexibility.

Compared with SN74LVC1G135DBVR and 74AUP1G135GW,125, the M74VHC1G135DFT1G-L22038 uniquely combines 5.5 V overvoltage tolerance, IOFF, and 2000 V HBM ESD in a single SC-74A package - making it the only option among the three qualified for industrial hot-swap and automotive body-control applications without supplemental protection.
