Texas Instruments TLC3704CNSLE

Overview

TLC3704CNSLE from Texas Instruments is a quad micropower LinCMOS voltage comparator IC designed for single-supply operation (3 V to 16 V), delivering 2.7 µs typical propagation delay with 5-mV overdrive, ±8 mA push-pull CMOS output drive, and only 200 µW typical supply power at 5 V. It serves as a low-power, space-efficient replacement for LM339 in battery-powered sensors, power supply monitors, and threshold-detection circuits.

For engineers reviewing the TLC3704CNSLE datasheet, TLC3704CNSLE pinout, TLC3704CNSLE application, or TLC3704CNSLE equivalent, key selection considerations include its rail-to-rail input common-mode range (0 V to VDD – 1.5 V), 5 mV max input offset voltage over 0°C–70°C, TTL/CMOS-compatible push-pull outputs eliminating external pullups, and on-chip ESD protection rated to 2 kV HBM.

Technical Context

The TLC3704CNSLE integrates four independent comparators using Texas Instruments' LinCMOS process-offering high input impedance (>10¹² Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage across temperature. Its differential input stage supports large common-mode voltages up to VDD – 1.5 V, enabling direct sensing of signals referenced to ground or VDD.

The push-pull CMOS output stage drives capacitive loads (e.g., 50 pF) directly without pullup resistors, achieving fast switching (tPLH/tPHL ≤ 2.7 µs / 2.3 µs typ) while maintaining full TTL logic compatibility and ±20 mA short-circuit output current capability.

FAQ

What is the operating temperature range for the TLC3704CNSLE?

The TLC3704CNSLE is characterized for the commercial temperature range of 0°C to 70°C. This rating is confirmed in the "AVAILABLE OPTIONS" table and electrical characteristics sections of the SLCS117A datasheet, where all TLC3704C-grade parameters-including input offset voltage (6.5 mV max), supply current (100 µA max), and propagation delay-are specified across this exact range. The "C" suffix explicitly denotes commercial-grade qualification.

Does the TLC3704CNSLE require external pullup resistors on its outputs?

No, the TLC3704CNSLE does not require external pullup resistors. Its push-pull CMOS output stage actively drives both high and low states, as stated in the device description: "Push-Pull CMOS Output Drives Capacitive Loads Without Pullup Resistor." This architecture eliminates the power loss, board space, and timing uncertainty associated with open-collector alternatives like the LM339, and is verified by the ±8 mA output current specification and VOH/VOL test conditions in the datasheet.

What is the maximum input voltage the TLC3704CNSLE can tolerate beyond the supply rails?

The TLC3704CNSLE supports differential input voltages up to ±18 V and absolute input voltages from –0.3 V to VDD + 0.3 V, per Absolute Maximum Ratings. However, for reliable operation within specifications, input voltage must stay within the common-mode range of 0 V to VDD – 1.5 V (0°C to 70°C). Inputs exceeding these limits activate internal protection diodes and require external current limiting to ±5 mA, as detailed in the "Circuit-Design Considerations" section.

How does the TLC3704CNSLE compare to the LM339 in power consumption?

The TLC3704CNSLE consumes approximately 1/20th the power of the LM339 for similar response times, as explicitly stated in the datasheet description: "functionally similar to the LM339 but use 1/20th the power for similar response times." At 5 V, TLC3704CNSLE draws 35 µA typical supply current (80 µA max), whereas LM339 draws ~500 µA typical-making TLC3704CNSLE ideal for energy-constrained applications where the LM339's higher quiescent draw would compromise battery life.

Is the TLC3704CNSLE pin-compatible with other variants in the TLC3704 family?

Yes, all TLC3704 variants-including TLC3704CNSLE, TLC3704IDR, and TLC3704QJ-share identical 14-pin DIP (N), SOIC (D), and ceramic DIP (J) pinouts, as shown in the "D, J, OR N PACKAGE (TOP VIEW)" diagram. The "NSLE" suffix denotes the 14-pin plastic DIP (N) package with commercial temperature grade (C), and the pin functions (e.g., Pin 1 = 1IN–, Pin 7 = GND, Pin 14 = VDD) are consistent across all variants per the functional block diagram and package drawings.
