Product details
Overview
TLV3202AIDGK from Texas Instruments is a dual-channel, 40ns propagation delay, microPOWER comparator with push-pull outputs, rail-to-rail inputs extending 200mV beyond supply rails, 1mV input offset voltage, and 40µA quiescent current per channel-designed for high-speed threshold detection in portable communications and test equipment.
For engineers reviewing the TLV3202AIDGK datasheet, TLV3202AIDGK pinout, TLV3202AIDGK application, or TLV3202AIDGK equivalent, this page delivers verified electrical specs, package-confirmed pin functions, industrial-temperature operation (–40°C to 125°C), and real-world implementation context for fast, low-power analog decision-making circuits.
Technical Context
The TLV3202AIDGK integrates two independent comparators in a single 8-pin VSSOP package, each featuring internal 1.2mV hysteresis for noise immunity and no phase inversion when inputs exceed supply rails. Its push-pull output stage delivers ±48mA short-circuit sourcing/sinking capability at 5V and maintains stable 40ns propagation delay across 2.7V–5.5V supply and –40°C to 125°C.
Input common-mode range spans (VEE – 0.2V) to (VCC + 0.2V), enabling direct interfacing with overvoltage-tolerant sensors or AC-coupled signals without external level-shifting. ESD protection includes ±2000V HBM and ±1000V CDM per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 40ns typical at 5V, 20mV overdrive, 15pF load - enables sub-25MHz digital edge detection in sampling systems. |
| Quiescent Current | 40µA per channel at 25°C - supports battery life >1 year in always-on portable monitoring nodes. |
| Input Offset Voltage | 1mV max at 25°C, 6mV max over full temperature range - ensures ≤0.2% trip-point error in precision threshold applications. |
| Supply Range | 2.7V to 5.5V single supply - interoperable with Li-ion, USB, and industrial 3.3V/5V rails without regulation. |
| Input Common-Mode Range | Extends 200mV beyond both rails - eliminates need for external biasing in AC-coupled zero-cross detection. |
| Output Type | Push-pull CMOS - drives logic inputs directly without pull-up resistors, reducing BOM count and board space. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial PLC, and telecom base station environments. |
Pinout & Package
TLV3202AIDGK is housed in an 8-pin VSSOP package (3.00mm × 3.00mm body size) with exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN– (Pin 2) | Negative input, Comparator 1 | Differential input node referenced to 1IN+; accepts signals up to 0.2V beyond VCC or GND. |
| 1IN+ (Pin 3) | Positive input, Comparator 1 | Primary reference input for first comparator; used with external hysteresis resistors or voltage references. |
| 1OUT (Pin 1) | Output, Comparator 1 | CMOS push-pull output driving 4mA load within 175mV of rails at 5V - compatible with 3.3V/5V logic families. |
| 2IN– (Pin 6) | Negative input, Comparator 2 | Independent second comparator input; electrically isolated from Channel 1 for dual-threshold designs. |
| 2IN+ (Pin 5) | Positive input, Comparator 2 | Configurable reference input for second channel; supports independent hysteresis or shared reference topologies. |
| 2OUT (Pin 7) | Output, Comparator 2 | Separate push-pull output with identical drive strength and rail-swing as 1OUT - enables parallel event detection. |
| GND (Pin 4) | Negative supply | Common return path for both comparators; must be low-impedance to minimize ground bounce in high-speed switching. |
| VCC (Pin 8) | Positive supply | Single 2.7V–5.5V supply powering both channels; decoupling capacitor required within 1cm for stable 40ns response. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with 200mV overvoltage tolerance | Enables direct connection to unregulated sensor outputs or AC-coupled sources without clamping diodes or level shifters. |
| Internal 1.2mV hysteresis | Reduces false triggering from noise on slow-rising signals - eliminates need for external positive feedback resistors in basic threshold detection. |
| No phase inversion at overvoltage | Maintains correct output polarity even when inputs exceed supply rails - critical for fault-monitoring circuits where input transients are expected. |
| 40ns propagation delay at 2.7V | Supports reliable pulse-width monitoring down to 25ns minimum pulse width - suitable for PWM duty-cycle validation in motor control. |
| ±48mA short-circuit output drive | Drives LEDs, small relays, or logic gates directly without buffer stages - simplifies discrete component count in compact designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7235MMX/NOPB | 75ns propagation delay, open-drain output, 65µA IQ, same 8-pin VSSOP footprint | Lacks push-pull drive; requires external pull-up for logic-level output; higher power consumption | Select when cost sensitivity outweighs speed requirement and open-drain flexibility is needed for wired-OR bus interfaces. |
| TLV3502CDR | 4.5ns propagation delay, 1.8V–5.5V supply, same push-pull output, but only 1.5mV offset and no 125°C rating | Higher speed but limited to –40°C to 85°C; not qualified for extended industrial temperature use | Select when sub-5ns response is mandatory and ambient temperature remains below 85°C - e.g., lab-grade instrumentation. |
Compared with LMV7235MMX/NOPB and TLV3502CDR, TLV3202AIDGK uniquely balances 40ns speed, 40µA ultra-low power, push-pull drive, and full –40°C to 125°C qualification - making it optimal for battery-powered industrial edge devices requiring long-term reliability under thermal stress.

FAQ
What is the maximum capacitive load the TLV3202AIDGK can drive while maintaining 40ns propagation delay?
The TLV3202AIDGK maintains its specified 40ns propagation delay up to 15pF capacitive load at 5V supply and 20mV input overdrive, as confirmed in Section 6.6 of the official datasheet. Beyond 15pF, delay increases linearly - e.g., ~55ns at 50pF - due to RC time constant effects on the push-pull output stage. For loads >30pF, layout optimization and local decoupling are recommended to preserve timing integrity in the TLV3202AIDGK.
Does the TLV3202AIDGK require external hysteresis for stable operation with noisy input signals?
No - the TLV3202AIDGK includes 1.2mV of internal hysteresis, which provides inherent noise immunity for typical industrial signal levels. External hysteresis is only needed when system-level noise exceeds this margin or when precise, user-defined hysteresis width (e.g., >5mV) is required. The internal hysteresis is factory-trimmed and temperature-stable, eliminating calibration overhead in the TLV3202AIDGK.
Can the TLV3202AIDGK operate from a 2.5V supply?
No - the absolute minimum recommended supply voltage for the TLV3202AIDGK is 2.7V, per Section 6.3 of the datasheet. Operation at 2.5V falls outside specified conditions and may result in increased propagation delay, reduced output swing, or failure to switch reliably. While the device may function intermittently at 2.5V, TI does not guarantee performance, and system validation is not supported for the TLV3202AIDGK below 2.7V.
Is the TLV3202AIDGK pin-compatible with the TLV3202IDR (SOIC-8 variant)?
Yes - both TLV3202AIDGK (VSSOP-8) and TLV3202IDR (SOIC-8) share identical pin numbering, pin functions, and electrical specifications. The only difference is package type: DGK uses a 3.00mm × 3.00mm VSSOP body, while DR uses a 4.90mm × 3.91mm SOIC body. Layout redesign is required for footprint interchangeability, but schematic integration and firmware logic remain unchanged for the TLV3202AIDGK.
What is the input bias current specification for the TLV3202AIDGK over temperature?
The TLV3202AIDGK exhibits input bias current of 1pA typical at 25°C, with a maximum of 5nA over the full –40°C to 125°C range, as specified in Section 6.5. This ultra-low bias enables high-impedance sensor interfacing (e.g., pH electrodes or photodiode transimpedance amplifiers) without significant DC error - a key advantage distinguishing the TLV3202AIDGK from higher-bias comparator alternatives.
