Product details
Overview
NCX2220GF,115 from NXP Semiconductors is a dual low-voltage, rail-to-rail input/output comparator optimized for ultra-low-power operation at 1.3 V to 5.5 V supply. It delivers 5 μA typical supply current per comparator, 0.8 μs typical propagation delay at 20 mV overdrive, and internal 9 mV hysteresis-enabling robust threshold detection in battery-powered portable electronics.
For engineers reviewing the NCX2220GF,115 datasheet, NCX2220GF,115 pinout, NCX2220GF,115 application, or NCX2220GF,115 equivalent, this device supports precision zero-crossing detection, Schmitt-trigger oscillation, one-shot timing, and logic-level translation in space-constrained, low-voltage systems requiring stable response under varying temperature (−40 °C to +85 °C) and supply conditions.
Technical Context
The NCX2220GF,115 integrates two independent comparators with complementary P/N-channel output stages enabling rail-to-rail swing into loads up to 5 mA while minimizing shoot-through current. Its input stage operates down to 1.3 V with common-mode range extending 0.1 V beyond both rails-eliminating phase inversion during overdrive.
Internal hysteresis (typ. 9 mV) provides noise immunity without external components; propagation delay remains stable across 1.3–5.5 V supply and −40 °C to +85 °C ambient, with ESD robustness exceeding 2000 V HBM and 1000 V CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.3 V to 5.5 V functional operation-supports direct integration into 1.8 V, 3.0 V, and 5.0 V systems without level-shifting. |
| Supply current per comparator | 5.0 μA typical-enables multi-year battery life in always-on sensor monitoring or wake-up circuits. |
| Propagation delay | 0.8 μs typical at 20 mV overdrive-ensures fast response for timing-critical edge detection and oscillator applications. |
| Hysteresis voltage | 9 mV typical-suppresses chatter on noisy inputs without external feedback resistors. |
| Input offset voltage | ±30 mV max over temperature-maintains reliable switching thresholds in precision analog front-ends. |
| Output drive capability | Rail-to-rail swing with ±5 mA sink/source-directly interfaces with CMOS logic or drives small capacitive loads without buffers. |
| Operating temperature | −40 °C to +85 °C-validated for industrial and consumer portable equipment environments. |
Pinout & Package
XSON8 package (SOT1089): extremely thin small outline, no leads, 8 terminals, body size 1.35 × 1.0 × 0.5 mm-designed for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Digital output of comparator 1; rail-to-rail CMOS-compatible signal for interfacing with microcontrollers or logic gates. |
| 2 | IN1− | Inverting input of comparator 1; accepts signals from VEE to VCC with no phase inversion even when overdriven. |
| 3 | IN1+ | Non-inverting input of comparator 1; used with IN1− to configure threshold detection or window comparators. |
| 4 | VEE | Negative supply terminal (typically ground); substrate pad connected via conductive die attach-must remain floating or tied to VEE if soldered. |
| 5 | IN2+ | Non-inverting input of comparator 2; enables independent dual-threshold sensing or differential signal comparison. |
| 6 | IN2− | Inverting input of comparator 2; supports mirrored configuration to comparator 1 for matched performance. |
| 7 | OUT2 | Digital output of comparator 2; fully independent of OUT1-allows concurrent decision-making in compact designs. |
| 8 | VCC | Positive supply terminal; accepts 1.3–5.5 V-no external decoupling required due to low-current, shoot-through-minimized output stage. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.1 V beyond VEE and VCC; output swings within 20 mV of rails-maximizes dynamic range in low-voltage systems. |
| Ultra-low quiescent current | 5 μA per comparator enables >10-year battery life in coin-cell-powered IoT sensors and wearables. |
| No phase inversion on overdrive | Guaranteed stable output polarity even when inputs exceed supply rails-critical for reliable zero-crossing and peak-detection circuits. |
| Integrated hysteresis | 9 mV typical internal hysteresis eliminates need for external positive feedback-reduces BOM count and layout area. |
| ESD robustness | HBM >2000 V and CDM >1000 V-survives handling and board-level transients without external protection diodes. |
Applications
| Cellular Telephones | Alarm & Security Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDR | Higher supply current (1.3 μA per comparator), wider supply range (1.8–16 V), no internal hysteresis. | Requires external hysteresis resistors; better suited for higher-voltage industrial sensors than ultra-low-power portable gear. | Select TLV3702IDR only if system voltage exceeds 5.5 V or if lower offset (±1.25 mV) outweighs current penalty. |
| MAX9062ASA+ | Lower propagation delay (120 ns), higher supply current (12 μA per comparator), no rail-to-rail inputs. | Input common-mode limited to VEE + 0.2 V to VCC − 0.2 V-unsuitable for overrail-sensing applications like zero-crossing. | Choose MAX9062ASA+ only when nanosecond-speed response is mandatory and supply is ≥2.7 V with clean input signals. |
Compared with TLV3702IDR and MAX9062ASA+, the NCX2220GF,115 uniquely balances ultra-low ICC (5 μA), guaranteed 1.3 V operation, rail-to-rail I/O, and integrated hysteresis-making it optimal for space- and energy-constrained portable electronics where external components must be minimized.
