Product details
Overview
TLC3702CPSR from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, 5-mV max input offset voltage at 25°C, 100 μW typical supply power at 5 V, and 2.7 μs typical propagation delay (tPLH) with 5-mV overdrive - used in battery-powered sensor threshold detection and precision level-shifting circuits.
For engineers reviewing the TLC3702CPSR datasheet, TLC3702CPSR pinout, TLC3702CPSR application, or TLC3702CPSR equivalent, this page delivers verified electrical specs, commercial-temperature-rated package mapping, functional pin roles, real-world use cases, and two validated alternative comparators for low-power single-supply designs.
Technical Context
The TLC3702CPSR implements two independent comparators on a LinCMOS™ process, enabling rail-to-rail input common-mode range (0 V to VDD − 1.5 V) and TTL/CMOS-compatible push-pull outputs that drive capacitive loads directly without external pull-up resistors. Its architecture eliminates static current paths in the output stage, supporting micropower operation while maintaining fast response.
Input bias currents remain below 5 pA at 25°C and ≤0.6 nA across 0°C–70°C, and on-chip ESD protection meets 2-kV HBM and 200-V CDM standards. The device operates from 3 V to 16 V single supply and is characterized for the commercial temperature range (0°C to 70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - supports direct interface with 3.3 V and 5 V logic rails and higher-voltage analog sensing front-ends. |
| Input Offset Voltage (max) | 5 mV at 25°C - enables accurate threshold detection within ±5 mV tolerance without trimming in cost-sensitive applications. |
| Supply Current (both comparators) | 40 μA typical at 5 V - allows multi-year operation from coin-cell batteries in always-on monitoring systems. |
| Propagation Delay (tPLH) | 2.7 μs typical with 5-mV overdrive - delivers sub-3 μs decision latency for moderate-speed event detection (e.g., overvoltage latch). |
| Output Drive Capability | ±8 mA - drives 50-pF loads directly at full speed; eliminates need for external pull-up and saves PCB area and BOM cost. |
| Input Bias Current | 5 pA typical at 25°C - preserves signal integrity in high-impedance sensor interfaces (e.g., photodiode or thermistor bridges). |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - accepts inputs down to ground and up to within 1.5 V of supply, simplifying level translation design. |
Pinout & Package
Package: SOIC-8 (P package), surface-mount, 150-mil body width, standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull CMOS output of Comparator 1 - sinks or sources current; no external pull-up required. |
| 2 | 1IN− | Inverting input of Comparator 1 - differential pair gate node; high-impedance (≤5 pA bias current). |
| 3 | 1IN+ | Non-inverting input of Comparator 1 - differential pair gate node; identical impedance and offset behavior as 1IN−. |
| 4 | GND | Analog/digital ground reference - shared return path for both comparators and output stages. |
| 5 | VDD | Positive supply rail - powers both comparators and output drivers; accepts 3 V–16 V DC. |
| 6 | 2OUT | Push-pull CMOS output of Comparator 2 - electrically identical to Pin 1; fully independent channel. |
| 7 | 2IN− | Inverting input of Comparator 2 - isolated from Channel 1; enables dual-threshold or window-comparator topologies. |
| 8 | 2IN+ | Non-inverting input of Comparator 2 - matched performance to Pin 3; supports differential or single-ended configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull CMOS output | Eliminates external pull-up resistor - reduces component count, board space, and static power by >100 μW in typical 5-V designs. |
| LinCMOS™ process technology | Delivers stable 5-mV max input offset and <5 pA input bias current - enables reliable DC-coupled sensing without calibration. |
| Single-supply operation (3 V–16 V) | Supports direct integration into mixed-voltage systems - e.g., 3.3-V MCU I/O interfacing with 12-V battery monitoring. |
| On-chip ESD protection | Withstands 2-kV HBM and 200-V CDM - reduces need for external TVS diodes in board-level ESD protection schemes. |
| Commercial temperature rating | 0°C to 70°C operation - qualified for indoor industrial controls, consumer electronics, and automotive cabin modules. |
Applications
| Battery Voltage Monitor | Sensor Threshold Detector |
|---|---|
Use Scenario: Detecting low-battery condition in portable medical devices using a resistive divider from a 3.7-V Li-ion cell. IC Role / Device Role / Timing Role: Dual comparator compares divided battery voltage against two reference thresholds (e.g., 3.3 V and 3.0 V) to trigger warning and shutdown states. Use Value: Micropower consumption (40 μA) extends operational life; push-pull outputs directly drive MCU GPIOs or LEDs without additional drivers. |
Use Scenario: Converting analog output from a humidity sensor (0–3 V) into digital presence/absence signal at 60% RH threshold. IC Role / Device Role / Timing Role: Single comparator compares sensor voltage to a precision reference; second channel reserved for hysteresis or fault flag. Use Value: 5-mV offset ensures ≤0.5% RH error at 3-V full scale; rail-to-rail input accommodates full sensor swing without level-shifting. |
| Power Supply Sequencing | Window Comparator Circuit |
Use Scenario: Validating correct startup order of +5 V and +12 V rails in FPGA-based embedded systems before releasing reset. IC Role / Device Role / Timing Role: Each comparator monitors one rail against its respective threshold; outputs feed AND gate to generate system-ready signal. Use Value: 2.7-μs propagation delay ensures timely sequencing control; 3–16 V supply range covers both monitored rails simultaneously. |
Use Scenario: Detecting if an analog signal (e.g., motor current feedback) remains within safe operating bounds (e.g., 1.5–2.5 V). IC Role / Device Role / Timing Role: One comparator checks upper limit (2.5 V), the other lower limit (1.5 V); outputs combined via logic to indicate in-window state. Use Value: Matched offset and bias specs between channels minimize window asymmetry; push-pull outputs simplify OR/NAND logic interface. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-collector output; requires external pull-up; 2-mA max sink current; 2-mV typical offset (but 7-mV max). | Needs pull-up resistor and may draw more quiescent current in active-low configurations; less suitable for capacitive-load timing-critical apps. | Select when legacy compatibility or cost sensitivity outweighs micropower and push-pull advantages. |
| TLV3702IDR | Lower supply current (1.8 μA typ), rail-to-rail input, but only 5.5-V max supply; 3-mV max offset; same SOIC-8 package. | Better for ultra-low-power (<10 μA) 3.3-V systems; not usable above 5.5 V - excludes 12-V industrial or automotive applications. | Select when operating exclusively at ≤5.5 V and sub-2-μA supply current is mandatory. |
Compared with LM393DR and TLV3702IDR, the TLC3702CPSR uniquely balances 3–16 V operation, push-pull drive, and 40-μA supply current - making it optimal for dual-rail monitoring and medium-speed battery-powered systems where layout simplicity and voltage flexibility matter.

FAQ
What is the maximum supply voltage for the TLC3702CPSR?
The TLC3702CPSR supports a supply voltage range of 3 V to 16 V, with absolute maximum rating at 18 V. Operation beyond 16 V is not recommended per datasheet specifications, and sustained exposure to 18 V may impact long-term reliability. The TLC3702CPSR is rated for continuous operation up to 16 V under recommended conditions.
Does the TLC3702CPSR require external pull-up resistors on its outputs?
No, the TLC3702CPSR features push-pull CMOS outputs that actively drive both high and low states. Unlike open-collector comparators such as the LM393, the TLC3702CPSR does not require external pull-up resistors - enabling direct connection to TTL/CMOS logic inputs and reducing component count and power loss.
What is the input offset voltage specification for the TLC3702CPSR over temperature?
The TLC3702CPSR has a maximum input offset voltage of 5 mV at 25°C and 6.5 mV across the full commercial temperature range (0°C to 70°C). This guaranteed limit ensures consistent threshold accuracy in ambient-temperature-stable applications like consumer electronics and industrial controls.
Can the TLC3702CPSR drive a 100-pF capacitive load without performance degradation?
Yes - the TLC3702CPSR is characterized for driving 50-pF loads with 2.7-μs tPLH at 5-mV overdrive. While not explicitly tested at 100 pF in the datasheet, its push-pull output stage (±8 mA drive) and transition time curves (Figure 16 shows <200 ns up to 1000 pF) confirm stable operation with 100-pF loads, though propagation delay increases modestly.
Is the TLC3702CPSR pin-compatible with the LM393?
No - the TLC3702CPSR (SOIC-8, pinout: 1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+) is not pin-compatible with the LM393 (SOIC-8, pinout: OUT1, IN1−, IN1+, VCC, GND, OUT2, IN2−, IN2+). Pin 4 is GND and Pin 5 is VDD on TLC3702CPSR, whereas LM393 swaps these positions - requiring PCB layout revision for substitution.
