Product details
Overview
TLC352IPWR from Texas Instruments is a dual CMOS voltage comparator with open-drain outputs, designed for low-power, wide-supply applications including battery-powered systems and industrial sensing interfaces. It operates from 2.7V to 18V, draws only 150µA typical supply current at 5V, features 5pA typical input bias current and 5mV max input offset voltage at 25°C, and supports common-mode input down to ground.
For engineers reviewing the TLC352IPWR datasheet, TLC352IPWR pinout, TLC352IPWR application, or TLC352IPWR equivalent, key selection criteria include its industrial temperature range (−40°C to 85°C), TSSOP-8 package, open-drain output compatibility with TTL/MOS/CMOS, and pin-compatibility with LM393 in level-shifted or wired-AND configurations.
Technical Context
The TLC352IPWR integrates two independent high-impedance comparators fabricated in CMOS technology, each with rail-to-rail common-mode input range extending to ground and differential input voltage tolerance up to ±VDD. Its open-drain n-channel output stage enables flexible pull-up to voltages up to 16V independent of VDD, supporting logic-level translation and wired-AND bus topologies.
It delivers 200ns typical propagation delay at 5V with 100mV overdrive and maintains ultra-low input bias current (5pA typ) and high input impedance (>10¹²Ω) across the full industrial temperature range, making it suitable for precision threshold detection in high-impedance sensor front-ends and low-quiescent-power monitoring circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Bipolar input stage; 250nA input bias current; 2mV typical offset; 0.8mA supply current per channel. | Higher power consumption and input loading limit use with high-Z sensors or battery systems. | Select LM393DR only when cost is primary and input impedance >1MΩ is acceptable. |
| TLC372IPWR | Same CMOS process; 10pA input bias; 10mV max offset; 75µA supply current per channel; identical TSSOP-8 package. | Lower power but higher offset - better for ultra-low-IQ designs where 10mV trip tolerance is acceptable. | Choose TLC372IPWR when minimizing supply current is critical and offset tolerance can be relaxed by 5mV. |
Compared with LM393DR, TLC352IPWR offers 50× lower input bias current and 5× lower supply current, enabling high-impedance sensor interfacing and extended battery life; versus TLC372IPWR, it trades 2.5× higher supply current for 2× lower input offset voltage, favoring precision threshold detection over ultra-low power.

FAQ
What is the maximum supply voltage for the TLC352IPWR?
The TLC352IPWR supports a maximum supply voltage of 18V, as specified in its Absolute Maximum Ratings table. Operation beyond this voltage risks permanent damage. For reliable long-term performance, TI recommends staying within the Recommended Operating Conditions of 2.7V to 16V - the TLC352IPWR is fully characterized and guaranteed across this 13.3V range at temperatures from −40°C to +85°C.
Does the TLC352IPWR support rail-to-rail input common-mode range?
The TLC352IPWR supports a common-mode input voltage range that includes ground (0V) and extends up to VDD − 1.5V over the full industrial temperature range. It does not support true rail-to-rail input (i.e., up to VDD), but the inclusion of ground enables direct interfacing with ground-referenced signals without level-shifting circuitry - a key advantage over many bipolar comparators.
Can the TLC352IPWR outputs drive a 5V logic input when powered from a 3.3V supply?
Yes - the TLC352IPWR features open-drain outputs that can be pulled up to any voltage between 0V and 16V, independent of the VDD supply. When powered from 3.3V, connecting a 5V pull-up resistor to OUT A or OUT B allows the device to assert a valid HIGH logic level (near 5V) to downstream 5V CMOS or TTL inputs, enabling seamless voltage-level translation in mixed-supply systems.
Is the TLC352IPWR pin-compatible with the LM393 in a TSSOP-8 footprint?
No - the LM393 is only available in SOIC-8 (D) and PDIP-8 (P) packages, not TSSOP-8. However, the TLC352IPWR is pin-compatible with the LM393 *functionally and electrically* in the same 8-pin dual-comparator configuration: Pin 1 (OUT A), Pin 2 (IN− A), Pin 3 (IN+ A), Pin 4 (GND), Pin 5 (IN+ B), Pin 6 (IN− B), Pin 7 (OUT B), Pin 8 (VCC). Layout adaptation is required due to TSSOP-8's smaller footprint and 0.65mm pitch versus SOIC-8's 1.27mm pitch.
What is the typical input offset voltage drift over temperature for the TLC352IPWR?
The TLC352IPWR datasheet specifies a maximum input offset voltage of 7mV across the full industrial temperature range (−40°C to +85°C), with 5mV maximum at 25°C. While the datasheet does not publish a typical drift coefficient (µV/°C), Figure 5-1 shows measured offset vs. temperature for five units, indicating typical drift within ±1.5mV over −40°C to +85°C - consistent with CMOS comparator performance and sufficient for most industrial threshold-detection applications.
