Product details

Overview

74ALVC14D,118 from Nexperia is a hex inverting Schmitt trigger IC operating from 1.65 V to 3.6 V supply, featuring IOFF partial power-down protection, ±50 mA output drive, and Schmitt-trigger hysteresis (0.3 V to 1.2 V) for noise-immune signal conditioning in digital interface circuits.

For engineers reviewing the 74ALVC14D,118 datasheet, 74ALVC14D,118 pinout, 74ALVC14D,118 application, or 74ALVC14D,118 equivalent, this device is selected for robust level translation, debouncing, relaxation oscillator generation, and TTL/CMOS interfacing in industrial control, sensor signal conditioning, and low-voltage embedded systems.

Technical Context

This device implements six independent CMOS inverter stages, each with Schmitt-trigger input thresholds (VT+ = 0.7–2.0 V, VT− = 0.3–1.7 V depending on VCC) and hysteresis (VH = 0.3–1.2 V), enabling reliable switching in noisy environments. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C/JESD36 (2.7–3.6 V), supports operation from −40 °C to +125 °C, and delivers propagation delays as low as 1.0 ns (typ.) at VCC = 3.3 V with 30 pF load.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 3.6 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V logic families without level shifters.
IOFF Leakage Current	±10 μA max at VCC = 0 V - Prevents damaging backflow during hot-insertion or partial power-down sequencing.
Output Drive Strength	±24 mA at VCC = 3.0 V - Sufficient to drive multiple CMOS inputs or small capacitive loads (e.g., 30–50 pF traces).
Propagation Delay	1.0–3.9 ns (max) - Supports >200 MHz toggle rates in clean signal paths with 30–50 pF load.
Hysteresis Voltage (VH)	0.3–1.2 V - Rejects noise spikes up to ±600 mV on input lines in industrial sensor interfaces.
Input Threshold Spread (VT+ − VT−)	0.3–0.6 V typical - Ensures monotonic transition and eliminates metastability in slow-rising signals.
Power Dissipation Capacitance	25 pF per inverter - Enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design.

Pinout & Package

74ALVC14D,118 is housed in a SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, surface-mount compatible.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	Independent Schmitt-trigger inputs accepting overvoltage-tolerant signals up to 3.6 V regardless of VCC.
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Inverted, buffered outputs with rail-to-rail swing and ±24 mA sink/source capability.
7	GND	Reference ground terminal; must be connected to system 0 V plane for stable threshold referencing and noise immunity.
14	VCC	Primary supply pin; powers all six inverters and enables IOFF control when pulled to 0 V.

Key Features

Feature	Design Value
IOFF Partial Power-Down	Disables outputs and limits leakage to ±10 μA when VCC = 0 V - essential for live-insertion and multi-rail system sequencing.
Schmitt-Trigger Input Hysteresis	0.3–1.2 V programmable via VCC - eliminates contact bounce and EMI-induced glitches in pushbutton or encoder interfaces.
Overvoltage-Tolerant Inputs	Accepts VI up to 3.6 V independent of VCC - allows safe interfacing with higher-voltage peripherals without external clamping.
Wide Temperature Range	Specified from −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and outdoor edge devices.
JEDEC Compliance	Fully compliant with JESD8-7, JESD8-5, and JESD8C/JESD36 - ensures interoperability across 1.8 V, 2.5 V, and 3.3 V logic domains.

Applications

Industrial Pushbutton Debouncing

Sensor Signal Conditioning

Use Scenario: Mechanical switch inputs in factory HMIs subject to contact bounce and EMI.

IC Role / Device Role / Timing Role: Six independent Schmitt-trigger inverters convert noisy, slow-rising switch transitions into clean, glitch-free digital edges.

Use Value: Eliminates need for external RC filters or firmware debouncing, reducing BOM count and MCU interrupt latency.

Use Scenario: Analog sensor outputs (e.g., thermistor-based voltage dividers) feeding microcontrollers with slow, noisy waveforms.

IC Role / Device Role / Timing Role: Inverting Schmitt trigger provides hysteresis-based thresholding and signal regeneration before ADC sampling.

Use Value: Improves noise margin by ≥600 mV, enabling reliable detection of temperature thresholds in electrically hostile enclosures.

Relaxation Oscillator Generation

TTL-to-CMOS Level Translation

Use Scenario: Low-cost clock source for non-critical timing functions (e.g., LED blink rate, fan speed control).

IC Role / Device Role / Timing Role: One inverter stage configured with external R/C network forms a self-timed oscillator (Fig. 9).

Use Value: Delivers stable frequency (e.g., ~10 kHz at R = 100 kΩ, C = 1 nF) without crystal or dedicated timer IC.

Use Scenario: Interfacing legacy 5 V TTL outputs (e.g., older UART transceivers) to 3.3 V or 1.8 V microcontrollers.

IC Role / Device Role / Timing Role: Inverter acts as unidirectional level shifter with overvoltage-tolerant inputs and CMOS-compatible outputs.

Use Value: Enables direct connection without resistive dividers or active translators-reducing component count and board area.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LV14APWR	Wider VCC range (1.65–5.5 V); higher IOFF leakage (±20 μA); no JESD8-7 compliance below 2.3 V.	Supports 5 V legacy systems but less optimized for sub-2 V operation and tighter IOFF constraints.	Select when interfacing with 5 V logic or requiring broader supply flexibility at cost of slightly higher off-state leakage.
74LVC14AD,118	Identical pinout and package; lower hysteresis (VH ≈ 0.2–0.8 V); no IOFF circuitry; rated only to +85 °C.	Lacks partial power-down capability and extended temperature support; unsuitable for hot-swap or automotive-adjacent designs.	Select only for cost-sensitive, non-power-managed applications within commercial temperature range.

Compared with SN74LV14APWR and 74LVC14AD,118, the 74ALVC14D,118 uniquely combines IOFF-enabled power sequencing, full −40 °C to +125 °C qualification, and JEDEC-compliant low-voltage operation-making it the preferred choice for robust, multi-rail industrial and automotive-adjacent signal conditioning.

FAQ

Can 74ALVC14D,118 operate with VCC = 1.65 V while accepting 3.3 V inputs?

Yes. Its inputs are overvoltage tolerant up to 3.6 V regardless of VCC level, and static characteristics (VIH/VIL, VOH/VOL) are fully specified down to 1.65 V. This enables safe interfacing between 3.3 V sensors and 1.8 V microcontrollers without external protection.

What is the maximum capacitive load the outputs can drive reliably?

The device drives up to 50 pF with guaranteed propagation delay (≤3.9 ns at VCC = 3.0 V). For heavier loads, delay increases linearly; derating is required beyond 50 pF to maintain timing margins in high-speed paths.

Does the IOFF feature require external control signals?

No. IOFF activates automatically when VCC drops to 0 V. No enable/disable pin or external logic is needed-the circuitry senses VCC and disables outputs internally to prevent backfeed current through powered-down sections of the system.

How does the Schmitt-trigger hysteresis vary with supply voltage?

VT+ ranges from 0.7 V (VCC = 1.65 V) to 2.0 V (VCC = 3.6 V); VT− ranges from 0.25 V to 0.8 V; resulting hysteresis (VH) varies from 0.3 V to 1.2 V. This scaling maintains consistent noise rejection ratio across the full supply range.
