Product details

Overview

MC74VHC1GU04DF1G-L22038 from onsemi is a single unbuffered CMOS inverter in SC-88A (SOT-353) package, operating from 2.0 V to 5.5 V supply, with 2.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and input overvoltage tolerance up to 5.5 V. It enables level-shifting between 3 V and 5 V logic domains in compact portable and industrial control circuits.

For engineers reviewing the MC74VHC1GU04DF1G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered inverter topology, SC-88A footprint compatibility, 5.5 V-tolerant inputs for mixed-voltage interfacing, and −55 °C to +125 °C operating range for automotive and industrial environments.

Technical Context

The MC74VHC1GU04DF1G-L22038 implements a single-stage CMOS inverter without internal buffering, delivering fast switching with minimal propagation delay variation across voltage and temperature. Its input structure includes overvoltage protection diodes rated to 5.5 V independent of V_CC, enabling safe interfacing of 5 V signals into 3 V systems.

IOFF functionality provides partial power-down protection by limiting input leakage to ≤10 µA when V_CC = 0 V, supporting hot-insertion and multi-rail system designs. The device exhibits low dynamic power consumption via CPD = 22 pF and supports load capacitances up to 50 pF with guaranteed timing performance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 5.5 V - Enables operation across 3.3 V and 5 V logic families without level translators.
t_PD (typ)	2.5 ns at V_CC = 5 V, C_L = 15 pF - Supports >200 MHz toggle rates in oscillator and pulse-shaping applications.
Input Voltage Tolerance	Up to 5.5 V regardless of V_CC - Allows direct connection of 5 V microcontroller outputs to 3 V-powered MC74VHC1GU04DF1G-L22038 inputs.
I_OH/I_OL	±8 mA at V_CC = 3.0 V - Sufficient drive strength to fan out to multiple 74VHC inputs or small LED loads.
Operating Temperature	−55 °C to +125 °C - Qualified for under-hood automotive, industrial motor control, and extended-temperature embedded systems.
IOFF Leakage	≤10 µA at V_IN = 5.5 V, V_CC = 0 V - Prevents back-powering and signal corruption during partial power-down states.
C_IN	≤10 pF - Minimizes capacitive loading on driving gates, preserving signal integrity in high-speed routing.

Pinout & Package

MC74VHC1GU04DF1G-L22038 is packaged in SC-88A (SOT-353), a 5-pin, 2.0 mm × 1.25 mm surface-mount package with gull-wing leads and exposed pad option (not electrically connected). Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.

Pin/Terminal	Circuit Role	Design Meaning
1	No Connect (NC)	Internally unconnected; must remain floating or tied to GND/V_CC per layout best practice - no functional impact.
2	Input (A)	Inverting logic input; accepts TTL- or CMOS-compatible signals; 5.5 V tolerant regardless of V_CC.
3	GND	Digital ground reference; must be low-impedance connection to system ground plane for noise immunity.
4	Output (Y)	Inverted logic output; drives complementary CMOS loads with rail-to-rail swing and ±8 mA capability at 3 V.
5	V_CC	Positive supply; decoupling capacitor (0.1 µF ceramic) required within 3 mm of this pin for stable high-speed operation.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar unbuffered inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G04DBVR	Same SC-70-5 (SOT-353) package; 1.65–5.5 V V_CC; t_PD = 3.7 ns @ 3.3 V; IOFF supported.	Lower minimum V_CC enables 1.8 V system integration; slightly slower at 3.3 V but wider voltage margin.	Select when interfacing with 1.8 V FPGAs or low-power ASICs where 2.0 V minimum is insufficient.
74AUP1G04GW,125	SC-70-5 package; 0.8–3.6 V V_CC; t_PD = 6.1 ns @ 3.3 V; ultra-low ICC = 0.9 µA typical.	Optimized for sub-1 V logic and battery-critical applications; not 5 V tolerant - requires external clamping for 5 V inputs.	Select only for 1.2–3.3 V-only systems where power budget is <1 µA and 5 V interfacing is absent.

Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the MC74VHC1GU04DF1G-L22038 offers superior 5.5 V input tolerance and faster propagation at 5 V, making it optimal for mixed-voltage industrial and automotive interfaces where robustness outweighs ultra-low-power needs.

What is the maximum input voltage the MC74VHC1GU04DF1G-L22038 can tolerate when V_CC = 3.3 V?

The MC74VHC1GU04DF1G-L22038 supports DC input voltages up to 5.5 V regardless of V_CC level, verified per datasheet Section "Maximum Ratings" (VIN = −0.5 V to +6.5 V) and "Features" (Inputs Over-Voltage Tolerant up to 5.5 V). This allows safe connection of 5 V signals to its input pin A while powered from 3.3 V, eliminating external protection components.

Does the MC74VHC1GU04DF1G-L22038 support partial power-down operation?

Yes, the MC74VHC1GU04DF1G-L22038 features IOFF circuitry that limits input leakage current to ≤10 µA when V_CC = 0 V and VIN = 5.5 V, as specified in the DC Electrical Characteristics table. This prevents back-current flow and signal corruption during partial power-down states in multi-rail systems - a key requirement for hot-pluggable I/O modules.

What is the typical propagation delay of the MC74VHC1GU04DF1G-L22038 at 3.3 V supply?

The MC74VHC1GU04DF1G-L22038 has a typical propagation delay of 3.5 ns at V_CC = 3.3 V with C_L = 15 pF, per AC Electrical Characteristics table (t_PLH/t_PHL row, V_CC = 3.0–3.6 V column). This value is confirmed across −40 °C to +85 °C ambient temperature and supports reliable 100+ MHz toggle rates in oscillator and timing applications.

Which package type does the MC74VHC1GU04DF1G-L22038 use, and what are its dimensions?

The MC74VHC1GU04DF1G-L22038 uses the SC-88A (SOT-353) package, measuring 2.0 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. Mechanical dimensions are documented in Case 419A on page 6 of the datasheet, and the part marking "DF1G" confirms SC-88A variant per Ordering Information table.

Can the MC74VHC1GU04DF1G-L22038 be used in an oscillator circuit?

Yes, the MC74VHC1GU04DF1G-L22038 is explicitly recommended for oscillator applications in the datasheet's first paragraph and Features section. Its unbuffered inverter topology, low propagation delay (2.5 ns typ @ 5 V), and stable input/output thresholds make it suitable for Pierce and ring oscillators - commonly implemented with external crystal or RC network on pin A and feedback to Y.
