Product details
Overview
TC75W59FU,LF from Toshiba is a CMOS dual comparator IC with open-drain outputs, single-supply operation (1.8–7.0 V), 200–440 µA supply current, and propagation delays as low as 60 ns (tPHL at 5 V). It operates across −40 to +85 °C and is used in voltage monitoring, level detection, and window comparator circuits in industrial control and portable electronics.
For engineers reviewing the TC75W59FU,LF datasheet, TC75W59FU,LF pinout, TC75W59FU,LF application, or TC75W59FU,LF equivalent, key selection criteria include its rail-to-rail input range (VSS to VDD−0.9 V), 25 mA sink capability, ultra-low input bias current (1 pA typ.), and SSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TC75W59FU,LF integrates two independent high-precision comparators on a single silicon monolithic die using Toshiba's CMOS process. Each channel features an open-drain output enabling wired-OR logic and flexible pull-up configuration, and supports common-mode input voltages from ground up to VDD−0.9 V.
It delivers fast response times (tTHL = 3 ns typ. at 5 V) with low power consumption, making it suitable for battery-powered systems requiring rapid threshold detection without compromising quiescent current. Input offset voltage remains tightly controlled (±1 mV typ.) across temperature and supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 7.0 V - Enables direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Supply Current (IDD) | 200–440 µA typ. - Supports >10-year battery life in always-on sensing nodes. |
| Input Offset Voltage (VIO) | ±1 mV typ. - Ensures accurate threshold detection in precision analog monitoring. |
| Sink Current (Isink) | 25 mA max at VOL = 0.5 V - Drives LEDs, MOSFET gates, or TTL inputs directly. |
| Propagation Delay (tPHL) | 60 ns typ. at 5 V - Meets timing requirements for high-speed zero-crossing or pulse-width detection. |
| Common-Mode Input Range | VSS to VDD−0.9 V - Accepts inputs down to ground and near-rail-high signals without phase reversal. |
| Input Bias Current | 1 pA typ. - Minimizes loading error on high-impedance sensor sources (e.g., thermistors, photodiodes). |
Pinout & Package
TC75W59FU,LF is housed in an SSOP-8 (Small Outline Package, 0.65 mm pitch) with 1.25 mm body height and 0.021 g typical weight. The package is RoHS-compliant and optimized for automated surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input A | Accepts reference or signal for first comparator; high-impedance node (1 pA bias). |
| 2 | Non-inverting Input A | Accepts sensed signal for first comparator; supports rail-to-rail common-mode range. |
| 3 | Output A | Open-drain output - requires external pull-up; enables wired-OR with other comparators. |
| 4 | GND | Ground reference for both comparators and internal circuitry. |
| 5 | Non-inverting Input B | Signal input for second comparator; electrically isolated from Channel A. |
| 6 | Inverting Input B | Reference input for second comparator; matched offset and bias performance vs. Channel A. |
| 7 | Output B | Independent open-drain output - configurable with separate pull-up resistor. |
| 8 | VDD | Positive supply rail (1.8–7.0 V); powers both comparator channels and output stages. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 1 pA typ. - Preserves accuracy when interfacing with megaohm-range sensors. |
| Wide single-supply range | 1.8–7.0 V - Eliminates need for dual supplies in mixed-voltage systems. |
| Fast turn-off propagation delay | 60 ns typ. at 5 V - Enables sub-100 ns window detection in real-time control loops. |
| Open-drain outputs | Supports wired-OR logic and mixed-voltage level translation via external pull-up. |
| Rail-to-rail input capability | VSS to VDD−0.9 V - Allows direct sensing of ground-referenced or near-VDD signals. |
Applications
| Voltage Monitoring System | Battery Level Detection |
|---|---|
Use Scenario: Real-time monitoring of 3.3 V or 5 V supply rails for undervoltage lockout (UVLO) and overvoltage protection. IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel for lower threshold, one for upper threshold. Use Value: 60 ns tPHL ensures immediate shutdown response during supply transients, preventing system latch-up. | Use Scenario: Discrete battery state-of-charge estimation in portable medical devices using resistive divider feedback. IC Role / Device Role / Timing Role: Threshold comparator comparing divided battery voltage against stable reference. Use Value: 1 pA input bias avoids loading error on high-resistance dividers, preserving measurement fidelity. |
| Zero-Crossing Detector | Industrial Sensor Interface |
Use Scenario: AC line synchronization in motor controllers and dimmer circuits using transformer-coupled sine wave inputs. IC Role / Device Role / Timing Role: Fast comparator detecting polarity transitions with minimal delay jitter. Use Value: 3 ns tTHL and matched tPLH/tPHL ensure consistent zero-crossing timing across temperature and supply variation. | Use Scenario: Interfacing NTC thermistors or RTDs in HVAC control panels where long trace lengths introduce noise susceptibility. IC Role / Device Role / Timing Role: Precision level shifter and noise-immune threshold detector before microcontroller ADC input. Use Value: ±1 mV VIO and 1 pA II minimize drift-induced false triggers in noisy industrial environments. |
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 IDD (500 µA typ.); wider VIO (±2 mV max); no rail-to-rail input. | Less suitable for low-power battery systems or ground-sensing; better noise immunity at high frequencies. | Choose LM393DR only if cost sensitivity outweighs power and input range requirements. |
| TLV3702IDR | CMOS input; lower IDD (80 µA typ.); smaller VIO (±0.85 mV max); same SSOP-8 package. | Superior for ultra-low-power designs but rated only to 5.5 V supply; not drop-in for 7 V applications. | Select TLV3702IDR when operating ≤5.5 V and sub-100 µA quiescent current is critical. |
Compared with LM393DR and TLV3702IDR, the TC75W59FU,LF uniquely balances 7 V operation, rail-to-rail input, and 200 µA supply current - making it optimal for industrial 5 V/3.3 V systems needing robustness and precision without sacrificing efficiency.

FAQ
What is the maximum supply voltage rating for TC75W59FU,LF?
The TC75W59FU,LF has an absolute maximum supply voltage rating of ±3.5 V differential or 7 V total (VDD to VSS). Operating continuously above 7 V risks permanent damage. The recommended operating range is 1.8 V to 7.0 V, with electrical characteristics fully specified across this span per Toshiba's datasheet.
Does TC75W59FU,LF support rail-to-rail input operation?
Yes, the TC75W59FU,LF supports a wide common-mode input voltage range from VSS to VDD−0.9 V. This allows inputs to reach ground (rail) and approach within 0.9 V of the positive rail - effectively rail-to-rail for most practical 3.3 V and 5 V applications. It does not support true VDD-level input due to internal headroom constraints.
Can TC75W59FU,LF outputs be wire-OR'd with other open-drain comparators?
Yes, the TC75W59FU,LF features two independent open-drain outputs that can be externally connected to a shared pull-up resistor. This wired-OR configuration enables logical OR functionality across multiple comparators - commonly used in alarm consolidation or multi-threshold detection without additional logic gates.
What is the typical input offset voltage of TC75W59FU,LF at room temperature?
The typical input offset voltage of TC75W59FU,LF is ±1 mV at Ta = 25°C and VDD = 5 V, with a maximum of ±7 mV across temperature and process variation. This tight offset enables precise threshold detection in applications such as battery end-of-discharge monitoring and sensor zero-point calibration.
Is TC75W59FU,LF compatible with SSOP-8 footprint variants having 0.50 mm pitch?
No, TC75W59FU,LF is specifically packaged in SSOP8-P-0.65 (0.65 mm lead pitch). The TC75W59FK variant uses SSOP8-P-0.50A (0.50 mm pitch). These are mechanically incompatible footprints - attempting to mount TC75W59FU,LF on a 0.50 mm pitch board will result in solder bridging or open connections.
