Product details
Overview
TLC339CPWG4 from Texas Instruments is a quad differential voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 3 V to 16 V. It delivers 2.5 µs typical propagation delay with 5-mV overdrive, consumes only 200 µW typical at 5 V, and features 10¹² Ω typical input impedance - enabling precision level detection in battery-powered sensor interfaces and power supervision circuits.
For engineers reviewing the TLC339CPWG4 datasheet, TLC339CPWG4 pinout, TLC339CPWG4 application, or TLC339CPWG4 equivalent, key selection criteria include its commercial-temperature-range rating (0°C to 70°C), TSSOP-14 package footprint, open-drain output compatibility with wired-OR logic and mixed-voltage systems, and LinCMOS™ process advantages including ultra-low input bias current and stable offset voltage drift.
Technical Context
The TLC339CPWG4 implements four independent comparators using Texas Instruments' LinCMOS™ process, delivering CMOS-level power efficiency without sacrificing speed or input performance. Its architecture supports rail-to-rail common-mode input range (0 V to VDD−1.5 V) and integrates on-chip ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.
Each comparator features an open-drain MOS output stage capable of sinking up to 20 mA per channel, with total ground current limited to 60 mA. Input offset voltage is specified at ≤6.5 mV over 0°C to 70°C, and supply current remains stable across 3 V–16 V operation - making it suitable for wide-input-voltage industrial monitoring and automotive subsystems where supply rails vary.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher supply current (500 µA typ), slower response (1.3 µs min but higher variation), bipolar process, no ESD rating specified. | Less suitable for battery-powered or high-precision applications; acceptable for cost-driven industrial controls with relaxed accuracy. | Select LM339DR only if legacy design reuse or extreme cost sensitivity outweighs power and precision requirements. |
| TLC3704CDR | Push-pull (not open-drain) outputs, same LinCMOS™ process, identical supply range and speed, but incompatible output logic structure. | Cannot replace TLC339CPWG4 in wired-OR or mixed-voltage pull-up configurations without circuit redesign. | Choose TLC3704CDR only when active-high push-pull outputs are required and no shared-bus logic is needed. |
Compared with LM339DR and TLC3704CDR, the TLC339CPWG4 uniquely balances ultra-low power, precision offset, and open-drain flexibility - making it optimal for space-constrained, battery-aware, and multi-rail interface applications where output configurability is essential.

FAQ
What is the maximum operating temperature range for the TLC339CPWG4?
The TLC339CPWG4 is rated for the commercial temperature range of 0°C to 70°C. This specification is defined in the device's recommended operating conditions and confirmed across all electrical characteristics tables for the TLC339C grade. Operation outside this range may result in parametric deviation or functional failure.
Can the TLC339CPWG4 operate from a 3.3 V supply?
Yes, the TLC339CPWG4 supports single-supply operation from 3 V to 16 V, explicitly including 3.3 V. At 3.3 V, propagation delay increases slightly (to ~3.2 µs typ @ 5-mV overdrive), and output low voltage remains below 650 mV with 6 mA sink - ensuring reliable logic-level compatibility with 3.3 V microcontrollers.
Does the TLC339CPWG4 require external pull-up resistors on its outputs?
Yes, all four outputs of the TLC339CPWG4 are open-drain and require external pull-up resistors to define the high-state voltage level. The value depends on speed and load: 10 kΩ is typical for general-purpose use; lower values (e.g., 2.2 kΩ) improve rise time but increase power consumption when outputs are low.
Is the TLC339CPWG4 pin-compatible with the LM339?
No, the TLC339CPWG4 is not pin-compatible with the LM339. While both are quad comparators in 14-pin packages, the TLC339CPWG4 uses TSSOP-14 (PW) with different pin assignments - notably GND on pin 7 and VDD on pin 14 - whereas LM339 variants use PDIP/SOIC with GND on pin 4 and VDD on pin 16 (for 16-pin) or pin 14 (for 14-pin SOIC). Layout redesign is required.
What is the input common-mode voltage range for the TLC339CPWG4 at 5 V supply?
At VDD = 5 V, the TLC339CPWG4 supports a common-mode input voltage range of −0.2 V to 3.5 V (VDD−1.5 V), as specified in the recommended operating conditions. Inputs outside this range may forward-bias internal ESD diodes, requiring current limiting to <5 mA to prevent damage.
