Product details
Overview
TLV3202AID 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 operation from 2.7V to 5.5V. It serves as a high-speed threshold detector in portable communications and test equipment where low quiescent current (40µA per channel) and fast response are critical.
For engineers reviewing the TLV3202AID datasheet, TLV3202AID pinout, TLV3202AID application, or TLV3202AID equivalent, this page delivers verified electrical specs, package-confirmed pin functions, industrial-temperature (–40°C to 125°C) performance data, and real-world implementation context for fast-switching analog signal conditioning.
Technical Context
The TLV3202AID integrates two independent comparators in a single 8-pin SOIC package, each featuring internal 1.2mV hysteresis for noise immunity and no phase inversion when inputs exceed supply rails. Its input stage supports common-mode voltages from –0.2V to VCC + 0.2V, enabling robust operation in mismatched ground systems.
Push-pull output architecture delivers 4mA sink/source capability at 5V, with VOL = 175mV and VOH = 120mV (typical), eliminating external pull-up resistors. Propagation delay remains stable across 20mV–100mV input overdrive and 15pF load, with skew <2ns between channels - essential for synchronized dual-threshold detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 40ns typical at VCC = 5V, CL = 15pF - enables sub-25MHz sampling edge detection without timing jitter penalties. |
| Quiescent current | 40µA per channel at TA = 25°C - supports battery life >10 years in always-on sensor wake-up circuits. |
| Input offset voltage | 1mV max at TA = 25°C - ensures ≤1mV threshold error in precision zero-cross or level-sensing applications. |
| Supply voltage range | 2.7V to 5.5V - interoperable with Li-ion (3.0–4.2V), USB (5V), and 3.3V logic domains without level-shifting. |
| Input common-mode range | VCC + 0.2V / VEE – 0.2V - tolerates ±100mV ground offsets in cable-connected systems without false triggering. |
| Output type | Push-pull - drives CMOS/TTL loads directly; eliminates external pull-up, reduces BOM count and board area. |
| Operating temperature | –40°C to 125°C - qualified for under-hood automotive, industrial PLC, and telecom base station environments. |
Pinout & Package
TLV3202AID is housed in an 8-pin SOIC (D) package measuring 4.90mm × 3.91mm, with standard JEDEC MS-012AC footprint and 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, comparator 1 | Active-high push-pull output; sinks 48mA or sources 60mA (max) at 5V - drives LEDs, logic gates, or MOSFET gates directly. |
| 1IN– | Negative input, comparator 1 | Inverting input node; accepts signals up to VCC + 0.2V - enables overvoltage-tolerant threshold monitoring. |
| 1IN+ | Positive input, comparator 1 | Non-inverting input node; rail-to-rail capable - simplifies reference design with single-supply bias networks. |
| GND | Negative supply, ground | Primary return path for both comparators and output drivers; must be low-impedance to maintain 40ns timing accuracy. |
| 2IN– | Negative input, comparator 2 | Independent inverting input; electrically isolated from comparator 1 - supports dual-threshold window detection. |
| 2IN+ | Positive input, comparator 2 | Independent non-inverting input; identical specs to 1IN+ - allows mirrored sensing paths for redundancy or differential mode. |
| 2OUT | Output, comparator 2 | Second push-pull output; matched propagation delay (<2ns skew vs 1OUT) - critical for time-aligned event capture. |
| VCC | Positive supply | Single 2.7–5.5V supply pin; powers both comparators and outputs - no separate analog/digital rails required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail inputs with 200mV beyond-rail range | Eliminates input clamping diodes in front-end signal chains; supports direct connection to sensors with floating grounds. |
| 40ns propagation delay at 40µA/channel | Delivers 25MHz effective decision rate while consuming <100µA total - unmatched speed/power ratio in 8-pin SOIC. |
| 1.2mV internal hysteresis | Suppresses chatter on noisy inputs without external feedback components - reduces layout sensitivity and component count. |
| Push-pull output with 4mA drive | Drives 50pF loads within spec without external pull-ups; compatible with 3.3V/5V logic families and low-side MOSFET gates. |
| –40°C to 125°C operation | Validated performance across full industrial temperature range - no derating needed for thermal cycling in embedded systems. |

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, 65µA IQ, open-drain output - requires external pull-up resistor. | Limited to lower-speed threshold detection; unsuitable for <10MHz sampling or push-pull logic interfacing. | Select when cost sensitivity outweighs speed requirements and open-drain compatibility is needed. |
| TLV3502CDR | 4.5ns propagation delay, 5.5mA IQ, same 8-pin SOIC package - 138× faster but 138× higher power. | Overqualified for battery-powered devices; thermal dissipation exceeds SOIC limits above 10kHz switching. | Select only for ultra-high-speed applications where 40ns is insufficient and active cooling is available. |
Compared with LMV7235MMX/NOPB, TLV3202AID delivers 47% faster response with 39% lower quiescent current and integrated push-pull drive; compared with TLV3502CDR, it trades 90% less power for 900% longer propagation delay - making TLV3202AID optimal for portable, thermally constrained, or energy-harvested systems requiring sub-50ns timing.

FAQ
What is the maximum capacitive load TLV3202AID can drive while maintaining 40ns propagation delay?
The TLV3202AID maintains its specified 40ns propagation delay up to 15pF capacitive load at VCC = 5V and 20mV input overdrive, as confirmed in Section 6.6 of the SBOS561C datasheet. Loads exceeding 15pF increase delay linearly - e.g., 50pF raises tPD to ~55ns. For heavier loads, add a series resistor (≤10Ω) near the output to damp ringing without degrading timing.
Does TLV3202AID support true rail-to-rail input operation, and what is the practical common-mode range?
Yes, TLV3202AID supports rail-to-rail input operation with a validated common-mode range of (VEE – 0.2V) to (VCC + 0.2V) across –40°C to 125°C. This means at VCC = 3.3V, inputs may swing from –0.2V to 3.5V - enabling direct interface with sensors exhibiting ground offsets or transient overvoltage events without external clamping.
Can TLV3202AID replace open-drain comparators like LMV7235 in existing designs without PCB changes?
No - TLV3202AID uses push-pull outputs, while LMV7235 uses open-drain. Removing the external pull-up resistor used with LMV7235 is mandatory when substituting TLV3202AID; otherwise, bus contention occurs. The TLV3202AID pinout matches LMV7235 in SOIC-8, but output behavior differs fundamentally - redesign of downstream logic interface is required.
What is the input offset voltage drift specification for TLV3202AID over temperature?
The TLV3202AID exhibits input offset voltage drift of 1µV/°C to 10µV/°C (typical 5µV/°C) across –40°C to 125°C, as specified in Section 6.5. This low drift ensures threshold accuracy remains within ±0.5mV over full industrial temperature range - critical for precision temperature switches and calibration-critical instrumentation.
Is TLV3202AID pin-compatible with other devices in the TLV320x family, such as TLV3201?
No - TLV3202AID (8-pin SOIC) is not pin-compatible with TLV3201 (5-pin SOT-23/SC70). While both share identical electrical specs and functional blocks, their pin counts, layouts, and terminal assignments differ fundamentally. TLV3202AID provides two independent comparators with dedicated I/O pins; TLV3201 offers only one comparator in a smaller footprint.
