Product details

Overview

MC74VHC1G07DBVT1G from onsemi is a single non-inverting buffer IC with open-drain output, designed for level-shifting and wired-OR logic in 2.0 V to 5.5 V systems. It features CMOS-level input thresholds, 3.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and overvoltage-tolerant inputs/outputs up to 5.5 V - enabling reliable interfacing between 3 V and 5 V domains in automotive and industrial control circuits.

For engineers reviewing the MC74VHC1G07DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain compatibility with I²C bus pull-up networks, IOFF partial power-down support for hot-swap systems, AEC-Q100 qualification, SC-74A (SOT-23-5) package footprint, and guaranteed operation from −55 °C to +125 °C.

Technical Context

The MC74VHC1G07DBVT1G implements a single-stage CMOS buffer with open-drain output topology, requiring an external pull-up resistor to define high-state voltage. Its input structure tolerates voltages up to 5.5 V independent of VCC, supporting mixed-voltage signal translation without clamping diodes or level-shifters.

IOFF circuitry disables current flow when VCC = 0 V, preventing back-powering of powered-down rails during partial system shutdown. Propagation delays are specified across 15 pF and 50 pF loads, with tPZL/tPLZ asymmetry reflecting turn-on/turn-off timing differences inherent to open-drain drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V supply domains without voltage translation.
tPD (Typ)	3.5 ns at 5 V - enables high-speed digital signaling in clock distribution, enable lines, and status flag paths.
IOL (Max)	8 mA at 3.0 V - sufficient to drive standard I²C bus capacitance (400 pF) with <300 ns fall time using 2.2 kΩ pull-up.
VIN/VOUT Tolerance	Up to 5.5 V regardless of VCC - eliminates need for external protection diodes when interfacing legacy 5 V peripherals to modern low-voltage controllers.
IOFF Leakage	≤10 µA at 0 V VCC - ensures safe isolation during power sequencing and prevents unintended current paths in multi-rail systems.
Operating Temp	−55 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment.
Package	SC-74A (SOT-23-5), 3.0 mm × 1.5 mm - compact footprint compatible with high-density PCB layouts and automated SMT assembly.

Pinout & Package

MC74VHC1G07DBVT1G is housed in the SC-74A (SOT-23-5) package - a 3.0 mm × 1.5 mm surface-mount outline with 0.95 mm height and 0.95 mm lead pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.

Pin/Terminal	Circuit Role	Design Meaning
1	NC (No Connect)	Internally unconnected - must remain floating or grounded; no electrical function or routing required.
2	A (Input)	CMOS-level buffered input - accepts 0–5.5 V signals; VIH = 1.5 V min at 2.0 V VCC, enabling robust noise margin in noisy environments.
3	GND	Ground reference for all internal circuitry and output stage - requires low-impedance connection to system ground plane.
4	Y (Output)	Open-drain NMOS output - sinks current only; external pull-up defines logic high voltage and rise time; supports wired-AND/I²C bus topologies.
5	VCC	Positive supply rail - powers internal logic and output driver; decoupling capacitor (100 nF) recommended within 5 mm of this pin.

Key Features

Feature	Design Value
Overvoltage-Tolerant I/O	Inputs and outputs withstand 5.5 V even at 2.0 V VCC - enables direct connection to 5 V microcontroller GPIOs without level shifters.
IOFF Partial Power-Down	Blocks current flow when VCC = 0 V - prevents backfeeding into powered-down subsystems during hot-plug or battery backup transitions.
Low Propagation Delay	3.5 ns typical at 5 V - meets timing budgets for fast enable/disable control in power management and sensor interface circuits.
AEC-Q100 Qualified	Qualified to Grade 1 (−40 °C to +125 °C) and Grade 3 (−55 °C to +125 °C) - certified for automotive body electronics and ADAS domain controllers.
Pb-Free & RoHS Compliant	Halogen-free/BFR-free construction with "G" suffix - satisfies EU RoHS Directive 2011/65/EU and automotive ELV requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar non-inverting open-drain buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G07DBVR	Lower VCC range (1.65–5.5 V); 3.7 ns tPD at 3.3 V; TTL-compatible VIH/VIL; not AEC-Q100 qualified.	Targeted at commercial-grade portable electronics; lacks automotive qualification and extended temperature support.	Select when cost sensitivity outweighs automotive qualification needs and 1.65 V minimum VCC is required.
74AUP1G07GW,125	Ultra-low power (ICC ≤ 0.9 µA); VCC = 0.8–3.6 V only; 12 ns tPD at 3.0 V; no 5 V tolerance.	Suitable for battery-powered IoT nodes; incompatible with 5 V signal domains or industrial temperature ranges.	Choose for ultra-low static power in sub-1 V to 3.3 V always-on sensor nodes where speed and voltage range are secondary.

Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the MC74VHC1G07DBVT1G uniquely combines AEC-Q100 Grade 3 qualification, 5.5 V overvoltage tolerance, and 3.5 ns speed across 2.0–5.5 V - making it the only option qualified for automotive hot-cranking and industrial wide-temperature mixed-voltage control.

FAQ

What is the maximum input voltage rating for MC74VHC1G07DBVT1G?

The MC74VHC1G07DBVT1G supports DC input voltages up to 5.5 V regardless of VCC level - verified per Absolute Maximum Ratings table. This overvoltage tolerance applies to both input pin A and output pin Y, allowing safe interfacing with 5 V sources even when operating from a 2.0 V supply. The specification is tested per JEDEC JESD78 latch-up and ESD standards.

Does MC74VHC1G07DBVT1G support I²C bus operation?

Yes, MC74VHC1G07DBVT1G is commonly used in I²C level-shifting applications due to its open-drain output and 5.5 V tolerant input. When paired with a 2.2 kΩ pull-up to 5 V, it achieves ≤300 ns fall time at 400 kHz bus speeds. Its VIH = 1.5 V min at 2.0 V VCC ensures compatibility with standard I²C master output levels, and IOFF prevents back-current during bus arbitration.

What is the meaning of the "−Q" suffix in MC74VHC1G07DBVT1G−Q?

The "−Q*" suffix on MC74VHC1G07DBVT1G−Q* denotes automotive qualification per AEC-Q100 Rev G, including PPAP capability and unique site/control change requirements. It indicates that the device was manufactured and tested under automotive-specific process controls, with full traceability, extended temperature validation (−55 °C to +125 °C), and zero-defect screening protocols - distinct from commercial-grade variants like MC74VHC1G07DBVT1G without the suffix.

Can MC74VHC1G07DBVT1G replace MC74VHC1G07DFT1G in a design?

Yes, MC74VHC1G07DBVT1G can replace MC74VHC1G07DFT1G in most applications because both share identical electrical specifications, pinout, and logic function. The only difference is package: MC74VHC1G07DBVT1G uses SC-74A (SOT-23-5), while MC74VHC1G07DFT1G uses SC-88A (SOT-353). Layout redesign is required due to different pad dimensions and pin 1 orientation - SC-74A has 0.95 mm pitch vs. SC-88A's 0.65 mm pitch.

What is the purpose of the NC pin (Pin 1) on MC74VHC1G07DBVT1G?

Pin 1 of MC74VHC1G07DBVT1G is designated NC (No Connect) - it is internally unconnected and serves no electrical function. Per onsemi's datasheet, this pin must remain unconnected or tied to GND; routing traces to it is unnecessary and may introduce parasitic coupling. Its presence accommodates mechanical alignment in the SC-74A package mold and does not affect logic behavior or timing performance of MC74VHC1G07DBVT1G.
