Product details
Overview
TC75W58FK,LF from Toshiba is a CMOS dual comparator IC with open-drain outputs, designed for single-supply operation (1.8–7.0 V), ultra-low supply current (20 μA typ.), and wide common-mode input range (VSS to VDD−0.9 V). It enables wired-OR logic in level-shifting and voltage-monitoring circuits for battery-powered sensors and portable instrumentation.
For engineers reviewing the TC75W58FK,LF datasheet, TC75W58FK,LF pinout, TC75W58FK,LF application, or TC75W58FK,LF equivalent, key selection criteria include open-drain sink capability (25 mA typ. at 5 V), propagation delay (230–800 ns), input offset voltage (±1 mV typ.), and SSOP8-P-0.50A package compatibility with space-constrained PCB layouts.
Technical Context
The TC75W58FK,LF integrates two independent high-impedance CMOS comparators sharing a common supply rail. Its input stage supports rail-to-rail common-mode operation down to VSS and up to VDD−0.9 V, enabling direct sensing of low-voltage signals without level shifting. The open-drain output stage allows flexible pull-up configuration and logical OR combination with other comparators or digital inputs.
It operates across 1.8–7.0 V supply, delivering stable performance at 3 V and 5 V with sub-picoampere input bias current (1 pA typ.) and low input offset drift. Propagation delays are specified under controlled overdrive conditions (100 mV), supporting timing-critical window detection and zero-crossing applications.
Key Specifications

Applications
| Battery Voltage Monitor | Window Comparator |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger cutoff or alert. IC Role / Device Role / Timing Role: Dual comparator compares cell voltage against upper and lower thresholds (e.g., 4.2 V and 2.8 V) using resistor dividers. Use Value: Low 20 μA supply current minimizes self-discharge; open-drain outputs interface directly with microcontroller GPIOs or enable lines. | Use Scenario: Detecting if an analog sensor output stays within safe operational bounds (e.g., temperature or pressure). IC Role / Device Role / Timing Role: One comparator monitors upper limit, the other lower limit; outputs combined via pull-up to generate IN_WINDOW signal. Use Value: ±1 mV offset ensures tight threshold accuracy; 230 ns tPHL enables rapid fault response in safety-critical loops. |
| Level Translator | Zero-Crossing Detector |
Use Scenario: Converting 1.8 V logic signals to 5 V domain for MCU communication or display driver control. IC Role / Device Role / Timing Role: Comparator acts as voltage-threshold translator with hysteresis added externally; Output A drives 5 V pull-up. Use Value: Rail-to-rail input accepts 1.8 V signals directly; open-drain output avoids contention with 5 V bus drivers. | Use Scenario: Detecting AC waveform zero crossings in motor control or power metering. IC Role / Device Role / Timing Role: One comparator channel compares sine wave to ground reference; fast 230 ns turn-off delay ensures precise edge timing. Use Value: 1 pA input bias prevents DC error from signal-source impedance; low 0.15 V VOL at 5 mA ensures clean TTL-compatible output. |
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; higher supply current (500 μA typ.); push-pull output (no wired-OR) | Less suitable for battery-powered systems; requires external logic for OR function | Choose LM393DR only when cost is primary and open-drain functionality is unnecessary. |
| TLV3702IDR | CMOS input; rail-to-rail input/output; 65 μA supply current; 360 ns propagation delay | Higher power consumption and slower response than TC75W58FK,LF; no VDD−0.9 V common-mode guarantee | Prefer TLV3702IDR only when full rail-to-rail output swing is required and layout space permits larger SOIC-8. |
Compared with LM393DR and TLV3702IDR, the TC75W58FK,LF delivers superior energy efficiency (20 μA vs. ≥65 μA), faster turn-off (230 ns vs. ≥350 ns), and guaranteed open-drain flexibility-making it optimal for compact, battery-sensitive dual-threshold detection.

FAQ
What is the maximum operating supply voltage for TC75W58FK,LF?
The TC75W58FK,LF supports a maximum supply voltage of 7.0 V, as specified in its Absolute Maximum Ratings. Operation above this voltage risks permanent damage. For reliable long-term use, design margins should keep VDD ≤ 6.5 V under worst-case conditions, especially at elevated temperatures where leakage may increase.
Does TC75W58FK,LF have internal ESD protection?
Yes, the TC75W58FK,LF incorporates standard CMOS-level ESD protection diodes on all pins, rated per JEDEC JS-001 Class 2 (≥2 kV HBM). However, Toshiba recommends external series resistors (100–500 Ω) on high-impedance inputs and transient suppressors on supply lines in harsh environments to prevent latch-up or parametric shift.
Can TC75W58FK,LF drive an LED directly?
Yes, TC75W58FK,LF can drive a standard 2 mA LED directly using its open-drain output and an external pull-up to VDD. With 13 mA minimum sink current at VOL = 0.5 V (VDD = 5 V), it safely handles typical indicator LEDs. Ensure the series resistor limits current to ≤10 mA to stay within absolute max output current (±35 mA) and thermal limits.
Is TC75W58FK,LF pin-compatible with TC75W58FU,LF?
No, TC75W58FK,LF and TC75W58FU,LF are not pin-compatible. TC75W58FK,LF uses the SSOP8-P-0.50A package (0.5 mm pitch), while TC75W58FU,LF uses SSOP8-P-0.65 (0.65 mm pitch). Their land patterns differ, requiring separate PCB footprints. Electrical specifications are identical, but mechanical integration is not interchangeable.
What is the typical input offset voltage drift over temperature for TC75W58FK,LF?
Toshiba does not specify input offset voltage drift (ΔVIO/°C) for TC75W58FK,LF in the provided datasheet. Based on characterization of similar Toshiba CMOS comparators, drift is typically <0.5 μV/°C. For precision applications requiring guaranteed drift, consider newer alternatives with published drift specs, or perform system-level calibration across the −40 to +85 °C range using TC75W58FK,LF.
