Product details
Overview
TC75S59F,LF from Toshiba Electronic Devices & Storage Corporation is a CMOS single comparator with open-drain output, 100 μA typical supply current, ±1 mV typical input offset voltage, and operation from 1.8 V to 7 V single supply. It serves as a precision threshold detector in battery-powered sensor interfaces and level-shifting circuits.
For engineers reviewing the TC75S59F,LF datasheet, TC75S59F,LF pinout, TC75S59F,LF application, or TC75S59F,LF equivalent, key selection criteria include its rail-to-rail input range (VSS to VDD − 0.9 V), low input bias current (1 pA), fast propagation delay (tPHL = 60 ns at 3 V), and SSOP-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TC75S59F,LF employs a CMOS input stage enabling ultra-low input bias current (1 pA) and wide common-mode input range (0 V to 4.1 V at VDD = 5 V). Its open-drain output supports wired-OR logic and flexible pull-up voltage selection independent of VDD.
Designed for low-power analog signal conditioning, it operates across 1.8–7 V supply while maintaining sub-220 μA max IDD and ±7 mV max input offset voltage over temperature. Propagation delays are specified for both overdrive and TTL-step inputs, supporting timing-critical window detection and zero-crossing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 7 V single supply - enables direct interface with Li-ion, 3.3 V, and 5 V systems without level shifters |
| Input Offset Voltage | ±1 mV (typ), ±7 mV (max) - ensures accurate threshold detection in precision voltage monitoring |
| Supply Current | 100 μA (typ) at 3 V - extends battery life in always-on sensor nodes and portable instrumentation |
| Propagation Delay | tPHL = 60 ns (typ) at 3 V - supports high-speed edge detection in motor control feedback loops |
| Input Common-Mode Range | VSS to VDD − 0.9 V - allows sensing near ground or rail without external bias networks |
| Output Type | Open-drain - permits wired-OR configuration and independent pull-up to higher voltage domains |
| Sink Current | 18 mA (typ) at 3 V - drives LEDs, MOSFET gates, or microcontroller interrupt lines directly |
Pinout & Package
TC75S59F,LF is housed in a 5-pin SSOP (Shrink Small Outline Package) with 0.95 mm lead pitch, measuring 2.9 mm × 2.8 mm × 1.25 mm (L × W × H), optimized for compact consumer and industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; must be connected before VDD to prevent latch-up |
| 2 | OUT | Open-drain output; requires external pull-up resistor; sinks up to 18 mA at 3 V |
| 3 | IN(−) | Inverting input; accepts signals from VSS to VDD − 0.9 V; high-impedance (1 pA bias) |
| 4 | IN(+) | Non-inverting input; identical voltage range and impedance as IN(−) |
| 5 | VDD | Positive supply rail; supports 1.8–7 V; power-on sequencing must ensure VDD ≥ VSS before signal application |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 1 pA typical - eliminates significant error in high-impedance sensor bridges and photodiode amplifiers |
| Rail-to-rail input capability | VSS to VDD − 0.9 V - enables direct sensing of battery voltage, thermistor dividers, and DAC outputs |
| Low quiescent current | 100 μA at 3 V - reduces system standby power in IoT endpoints and wearables |
| Fast turn-off response | tPHL = 60 ns (typ) at 3 V - improves timing accuracy in pulse-width measurement and encoder decoding |
| CMOS latch-up mitigation | Specified I/O voltage limits (VSS ≤ VIN ≤ VDD) - guides safe power sequencing and ESD protection design |
Applications
| Battery Voltage Monitor | Overvoltage Protection Circuit |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger cutoff or alert. IC Role / Device Role / Timing Role: Precision comparator detecting when cell voltage crosses 4.2 V (full) or 2.8 V (low). Use Value: ±1 mV offset ensures <10 mV total error margin; open-drain output interfaces directly with MCU GPIO or PMIC enable pins. | Use Scenario: Preventing damage to downstream 3.3 V logic by disconnecting 5 V supply when transient overvoltage occurs. IC Role / Device Role / Timing Role: Fast-response comparator comparing sensed rail voltage against stable reference. Use Value: 60 ns tPHL enables reaction before destructive energy accumulates; 18 mA sink drives gate of protection MOSFET without buffer. |
| Zero-Crossing Detector | Window Comparator Input Stage |
Use Scenario: Converting AC line waveform into clean digital zero-crossing pulses for phase-controlled dimmers. IC Role / Device Role / Timing Role: High-impedance comparator sensing transformer-coupled AC signal referenced to midpoint bias. Use Value: 1 pA input bias avoids loading passive bias network; rail-to-rail input accommodates ±2 V peak signal without clamping diodes. | Use Scenario: Front-end stage for multi-threshold detection in environmental sensor hubs (e.g., temperature alarm bands). IC Role / Device Role / Timing Role: One half of dual-comparator system generating upper/lower boundary flags. Use Value: Open-drain output allows shared pull-up with second comparator for compact wired-OR window flag generation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV331M5X/NOPB | Push-pull output, higher supply current (80 μA min), wider temp range (−40°C to 125°C) | Requires level-shifting for mixed-voltage systems; unsuitable where wired-OR is needed | Select when driving capacitive loads or needing guaranteed push-pull drive without external components |
| TLV3701DBVR | Higher speed (420 ns tPHL), rail-to-rail input/output, but larger SOT-23-6 package | Not pin-compatible; occupies more board area; better for high-frequency PWM feedback | Select when faster response or full rail-to-rail output swing is required, and layout space permits SOT-23-6 |
Compared with LMV331M5X/NOPB and TLV3701DBVR, the TC75S59F,LF offers unique value in ultra-low-power, open-drain wired-OR configurations within minimal SSOP-5 footprint-ideal for space- and energy-constrained designs where output flexibility outweighs raw speed or extended temperature range.

FAQ
What is the maximum operating supply voltage for TC75S59F,LF?
The TC75S59F,LF supports a maximum supply voltage of 7 V on VDD relative to VSS. Absolute maximum ratings also permit ±3.5 V dual-supply operation, but the device is optimized for single-supply use from 1.8 V to 7 V. Exceeding 7 V risks permanent damage per Toshiba's absolute maximum ratings table.
Does TC75S59F,LF have rail-to-rail input capability?
Yes, the TC75S59F,LF features a wide common-mode input voltage range from VSS to VDD − 0.9 V. At VDD = 5 V, this spans 0 V to 4.1 V; at VDD = 3 V, it covers 0 V to 2.1 V. This enables direct interfacing with sensors, DACs, and battery terminals without external biasing resistors.
Can TC75S59F,LF drive an LED directly?
Yes, the TC75S59F,LF open-drain output can sink up to 18 mA (typ) at 3 V, sufficient to drive standard indicator LEDs with appropriate series resistance. For example, with a 3 V supply and red LED (VF ≈ 1.8 V), a 68 Ω resistor limits current to ~17.6 mA - well within the TC75S59F,LF's sink capability.
What is the typical input offset voltage of TC75S59F,LF at room temperature?
The TC75S59F,LF has a typical input offset voltage of ±1 mV at Ta = 25°C and VDD = 5 V, with a maximum of ±7 mV across temperature and process variation. This specification is confirmed in Toshiba's Electrical Characteristics tables and supports precision threshold detection in voltage-monitoring applications.
Is TC75S59F,LF susceptible to latch-up, and how is it mitigated?
Yes, the TC75S59F,LF uses a CMOS process that makes it susceptible to latch-up. Toshiba specifies strict precautions: ensure no I/O pin voltage exceeds VDD or drops below VSS, verify proper power-on sequencing (VDD established before inputs), and minimize noise coupling. These constraints are documented in the Absolute Maximum Ratings section and reliability notes.
