Product details

Overview

74LVC1G17GX4Z from Nexperia is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, accepts overvoltage-tolerant inputs up to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is qualified for -40 °C to +125 °C operation - enabling robust level translation in industrial sensor interfaces and low-power microcontroller I/O expansion.

For engineers reviewing the 74LVC1G17GX4Z datasheet, 74LVC1G17GX4Z pinout, 74LVC1G17GX4Z application, or 74LVC1G17GX4Z equivalent, this device serves as a compact, noise-immune buffer for cleaning slow-rising or noisy digital signals in space-constrained PCBs where voltage-level interoperability between 3.3 V and 5 V logic domains is required.

Technical Context

The 74LVC1G17GX4Z implements a CMOS-based Schmitt-trigger input stage with hysteresis (VH = 0.40–0.88 V depending on VCC), enabling reliable switching in presence of analog-like or slowly varying input waveforms. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

It supports unlimited input rise/fall times and direct TTL-level interfacing, with static input leakage ≤ ±1 μA and power-off leakage ≤ ±2 μA. Propagation delay ranges from 0.7 ns (min) to 7.0 ns (max) across 1.65–5.5 V supply range, ensuring timing predictability in both battery-powered and industrial control applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - enables direct use in 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters
Input Voltage Tolerance	Up to 5.5 V - allows safe connection to 5 V sources while powered from lower VCC (e.g., 3.3 V)
Output Drive Strength	±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or small capacitive traces
Hysteresis Voltage (VH)	0.40 V to 0.88 V - provides noise margin against EMI-induced glitches on long or unterminated lines
Propagation Delay (tpd)	0.7 ns (min) to 7.0 ns (max) - ensures deterministic timing across full voltage and temperature range
IOFF Leakage Current	≤ ±2 μA at VCC = 0 V - prevents damaging backfeed current during hot-swap or partial system power-down
Operating Temperature	-40 °C to +125 °C - supports under-hood automotive, industrial PLC, and outdoor IoT deployments

Pinout & Package

X2SON4 package (SOT1269-2): ultra-compact, leadless, thermally enhanced 4-terminal surface-mount package measuring 0.6 mm × 0.6 mm × 0.32 mm with side-wettable flanks for automated optical inspection.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for all internal circuitry and output return path
2	A	Schmitt-trigger input - accepts slow or noisy signals; hysteresis rejects sub-threshold noise
3	Y	Inverting-buffered output - drives downstream logic with rail-to-rail swing and ±24 mA capability
4	VCC	Positive supply - powers internal logic and output stage; IOFF activates when VCC = 0 V

Key Features

Feature	Design Value
Wide Supply Range	1.65–5.5 V operation eliminates need for external regulators in multi-rail systems
Overvoltage-Tolerant Inputs	5.5 V max input rating permits direct interface with legacy 5 V peripherals without clamping diodes
IOFF Partial Power-Down	Active output disable at VCC = 0 V prevents back-current damage during board hot-plug or sleep mode
High Noise Immunity	Typical hysteresis of 0.6 V at 3.0 V VCC suppresses >100 mV of common-mode noise on input traces
Ultra-Small X2SON4 Footprint	0.6 mm × 0.6 mm body enables placement in dense MCU peripheral routing zones or wearable PCBs

Applications

Industrial Sensor Interface

Microcontroller I/O Expansion

Use Scenario: Conditioning analog-output sensor signals (e.g., thermistor, potentiometer) before digitization by an MCU ADC or GPIO interrupt pin.

IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow-rising RC-filtered or EMI-coupled signals into clean digital edges for reliable edge detection.

Use Value: Eliminates false triggers caused by noise or slow transitions, improving system reliability without adding external RC components.

Use Scenario: Extending GPIO count of a low-pin-count MCU (e.g., ARM Cortex-M0+) to drive LEDs, buttons, or status indicators.

IC Role / Device Role / Timing Role: Level-translating buffer isolates MCU pins from higher-current loads while maintaining logic compatibility across 1.8 V/3.3 V domains.

Use Value: Enables direct drive of 3.3 V peripherals from 1.8 V MCU outputs with no external level shifter or pull-up resistors.

Automotive Body Control Module

IoT Edge Node Signal Conditioning

Use Scenario: Debouncing mechanical switch inputs (e.g., door latch, seat position) in automotive BCMs operating at 125 °C ambient.

IC Role / Device Role / Timing Role: Input buffer with hysteresis rejects contact bounce and conducted noise in harsh vehicle electrical environments.

Use Value: Reduces firmware debounce overhead and improves real-time response by delivering clean, glitch-free interrupts to the MCU.

Use Scenario: Cleaning RF-noise-contaminated wake-up signals (e.g., from LoRaWAN or BLE radio modules) in battery-powered edge nodes.

IC Role / Device Role / Timing Role: Low-quiescent-current Schmitt trigger converts noisy radio IRQ pulses into precise MCU wake events.

Use Value: Cuts average system current by eliminating spurious wake-ups, extending battery life beyond 5 years in deep-sleep configurations.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G17DBVR	5-pin SOT-23 package; same electrical specs but larger footprint (2.9 mm × 1.6 mm vs. 0.6 mm × 0.6 mm)	Less suitable for ultra-dense layouts; requires more PCB area and has higher thermal resistance	Select when standard SMT assembly infrastructure lacks X2SON4 reflow capability or optical inspection support
74LVC1G17GW	TSSOP5 package (1.25 mm body width); identical logic function and voltage specs but 3× larger footprint and higher parasitic capacitance	Better manual handling and probing; less optimal for high-frequency or space-constrained designs	Prefer for prototyping, test fixtures, or legacy production lines not calibrated for 0.6 mm pitch devices

Compared with SN74LVC1G17DBVR and 74LVC1G17GW, the 74LVC1G17GX4Z delivers identical Schmitt-trigger functionality in a 94% smaller footprint and 40% lower thermal resistance - making it optimal for miniaturized, thermally constrained, or high-volume consumer and automotive applications where board space and thermal performance are critical.

FAQ

Does the 74LVC1G17GX4Z support true bidirectional operation?

No. The 74LVC1G17GX4Z is a unidirectional Schmitt-trigger buffer with fixed input (A) and output (Y) terminals. It does not implement bus transceiver logic or direction control. Its IOFF feature only disables the output driver during power-down - it does not enable reverse signal flow or data latching.

Can the 74LVC1G17GX4Z be used with 1.2 V supply?

No. The absolute minimum supply voltage is 1.65 V per JEDEC JESD8-7 compliance. At 1.2 V, the device fails to meet guaranteed VOH/VOL specifications, threshold voltages collapse below usable levels, and IOFF behavior becomes undefined. For 1.2 V systems, consider NX1L1G17 or similar 1.1 V–3.6 V logic families.

What is the maximum capacitive load the 74LVC1G17GX4Z can drive reliably?

The datasheet specifies dynamic characteristics up to 50 pF load capacitance with defined tpd and waveform integrity. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot/ringing due to limited slew rate. For >100 pF loads, add a series resistor (22–47 Ω) near the output to dampen reflections and maintain signal integrity.

Is the X2SON4 package (SOT1269-2) compatible with standard reflow profiles?

Yes. The 74LVC1G17GX4Z in SOT1269-2 meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is qualified for standard SnPb and lead-free reflow profiles, including peak temperatures up to 260 °C. Its side-wettable flanks enable automated optical solder-joint inspection without X-ray.
