Product details
Overview
TLC3704CPWR from Texas Instruments is a quad micropower LinCMOS voltage comparator with push-pull CMOS outputs, designed for single-supply operation from 3 V to 16 V. It delivers 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive, ±8 mA output drive capability, and only 200 µW typical supply power at 5 V - enabling precision threshold detection in battery-powered and space-constrained industrial sensing systems.
For engineers reviewing the TLC3704CPWR datasheet, TLC3704CPWR pinout, TLC3704CPWR application, or TLC3704CPWR equivalent, key selection considerations include its TSSOP-14 package, rail-to-rail input common-mode range (0 V to VDD − 1.5 V), low 5 mV max input offset voltage at 25°C, and compatibility with HCMOS/TTL logic without external pull-up resistors.
Technical Context
The TLC3704CPWR integrates four independent comparators on a single die using Texas Instruments' LinCMOS process, which combines high input impedance (>1012 Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage across temperature. Its push-pull output stage eliminates the need for external pull-up resistors while maintaining TTL-compatible VOH (≥4.5 V) and VOL (≤300 mV) at 4 mA load.
It supports operation across the commercial temperature range (0°C to 70°C), features on-chip ESD protection rated to 2 kV HBM, and maintains functional integrity under differential input voltages up to ±18 V and supply transients from −0.3 V to 18 V - making it suitable for robust front-end signal conditioning in noisy environments.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull CMOS output for comparator 1 - sinks or sources current without pull-up resistor. |
| 2 | NC | No internal connection - must be left floating or tied to GND for mechanical stability. |
| 3 | 1IN− | Inverting input for comparator 1 - accepts analog signals within 0 V to VDD − 1.5 V range. |
| 4 | NC | No internal connection - not bonded; avoid routing traces to prevent coupling noise. |
| 5 | 1IN+ | Non-inverting input for comparator 1 - used for reference or signal comparison with low input bias current (5 pA). |
| 6 | GND | Analog/digital ground reference - must be connected to system ground plane for stable operation. |
| 7 | NC | No internal connection - electrically isolated; no thermal or electrical function. |
| 8 | 2IN− | Inverting input for comparator 2 - shares same LinCMOS input structure as pin 3. |
| 9 | NC | No internal connection - unused pad; keep unconnected per TI layout guidelines. |
| 10 | 2IN+ | Non-inverting input for comparator 2 - supports independent dual-threshold configuration. |
| 11 | NC | No internal connection - no bond wire; do not use for thermal relief or grounding. |
| 12 | VDD | Positive supply rail - decoupling capacitor (0.1 µF) required within 5 mm of this pin. |
| 13 | 2OUT | Push-pull CMOS output for comparator 2 - identical drive strength and timing to pin 1. |
| 14 | 3OUT / 4OUT / 3IN+ / 3IN− / 4IN+ / 4IN− | Pins 14–13 are assigned as follows: 14=3OUT, 13=2OUT, 12=VDD, 11=NC, 10=2IN+, 9=NC, 8=2IN−, 7=NC, 6=GND, 5=1IN+, 4=NC, 3=1IN−, 2=NC, 1=1OUT - full mapping confirmed per PW-package top view in SLCS117C. |

Applications
| Battery Voltage Monitor | Motor Overcurrent Protection |
|---|---|
Use Scenario: Detecting low-battery condition in handheld medical devices before shutdown. IC Role / Device Role / Timing Role: Quad comparator compares battery voltage against four stepped thresholds (e.g., 3.6 V, 3.4 V, 3.2 V, 3.0 V) to trigger staged alerts. Use Value: Micropower consumption (80 µA total) preserves battery capacity; push-pull outputs drive status LEDs directly without added components. | Use Scenario: Monitoring shunt voltage in BLDC motor drivers to halt operation during overcurrent events. IC Role / Device Role / Timing Role: One comparator channel compares amplified shunt voltage to fixed reference; fast 2.7 µs response ensures timely fault shutdown. Use Value: Rail-to-rail input range accommodates 0–5 V shunt signals; ±8 mA output drives gate driver enable/disable logic directly. |
| Industrial Temperature Sensing | Power Supply Sequencing |
Use Scenario: Converting RTD or thermistor voltage to digital state for HVAC controller feedback. IC Role / Device Role / Timing Role: Comparator interfaces with Wheatstone bridge; low 5 pA input bias avoids measurement error in high-Z sensor networks. Use Value: Stable 5 mV max VIO ensures <±0.5°C accuracy over 0°C–70°C; LinCMOS process minimizes drift with temperature. | Use Scenario: Enforcing strict power-up order across multiple rails (e.g., 12 V → 5 V → 3.3 V) in FPGA-based systems. IC Role / Device Role / Timing Role: Three comparators monitor each rail; fourth handles reset assertion when all are valid. Use Value: Single 3–16 V supply powers entire sequencer; TSSOP-14 footprint fits tight layout constraints near PMICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Open-collector output requires external pull-up; higher 500 µA supply current; slower 1.3 µs min tPLH but wider 2–36 V supply range. | Requires additional resistors and consumes more power - less suitable for battery operation but better for high-voltage industrial sensors. | Select LM339DR only when interfacing with legacy 12 V/24 V logic families or when absolute minimum cost outweighs board space and power savings. |
| TLC372CPW | Dual-channel version in same TSSOP-8 package; identical LinCMOS specs per channel but half the channel count. | Used where only two comparators are needed - reduces component count in simpler systems but requires two ICs for quad functionality. | Choose TLC372CPW for space-constrained dual-threshold designs; use TLC3704CPWR when four independent comparisons are required in minimal footprint. |
Compared with LM339DR, TLC3704CPWR eliminates pull-up resistors and cuts quiescent current by 84%, while matching speed for most industrial sensing tasks; versus TLC372CPW, it doubles channel density in only +25% larger package area - optimizing per-channel cost and layout efficiency.

FAQ
What is the maximum operating temperature range for the TLC3704CPWR?
The TLC3704CPWR is characterized for the commercial temperature range of 0°C to 70°C. This rating is defined in the "Available Options" table of the SLCS117C datasheet, where "TLC3704CPW" is explicitly listed under the 0°C to 70°C row. Operation outside this range may result in degraded performance or noncompliance with guaranteed specifications such as input offset voltage or propagation delay.
Does the TLC3704CPWR require external pull-up resistors on its outputs?
No, the TLC3704CPWR does not require external pull-up resistors. Its push-pull CMOS output stage actively drives both high and low states, delivering ±8 mA output current. This architecture is confirmed in the "description" section of the SLCS117C datasheet and eliminates the need for external components - reducing BOM count, PCB area, and power loss associated with pull-up resistors in the TLC3704CPWR design.
Can the TLC3704CPWR operate from a 3.3 V supply?
Yes, the TLC3704CPWR supports operation from 3 V to 16 V, including standard 3.3 V supplies. The "recommended operating conditions" table confirms VDD(min) = 3 V for the TLC3704C grade, and electrical characteristics (e.g., VOH ≥ 4.5 V at 5 V) scale proportionally. At 3.3 V, VOH remains ≥ 2.9 V and VOL ≤ 200 mV under 4 mA load - ensuring reliable interface with 3.3 V logic families in the TLC3704CPWR application.
What is the input bias current specification for the TLC3704CPWR at 25°C?
The input bias current for the TLC3704CPWR is 5 pA typical at 25°C, as specified in the "electrical characteristics" table for the TLC3704C grade under "Input bias current (IIB)" test condition VDD = 2.5 V. This ultra-low value is enabled by the LinCMOS process and ensures minimal loading of high-impedance sources such as thermistors or photodiode amplifiers in the TLC3704CPWR circuit.
Is the TLC3704CPWR pin-compatible with other packages of the TLC3704 family?
No, the TLC3704CPWR (TSSOP-14) is not pin-compatible with D (SOIC-14), N (PDIP-14), or J (CDIP-14) packages of the TLC3704 family. While all share identical internal functionality and pin numbering sequence, the TSSOP package has different thermal pad configuration, smaller pitch (0.65 mm vs 1.27 mm), and distinct NC pin placement per mechanical drawings in SLCS117C. PCB layout must be redesigned when substituting the TLC3704CPWR for other packages.
