Product details
Overview
TC75S58F,LF from Toshiba Electronic Devices & Storage Corporation is a CMOS single comparator with open-drain output, 10 μA typical supply current, ±1 mV input offset voltage, and operation from 1.8 V to 7 V single supply. It features a wide common-mode input range (VSS to VDD − 0.9 V) and supports wire-OR logic in level-shifting and interface applications.
For engineers reviewing the TC75S58F,LF datasheet, TC75S58F,LF pinout, TC75S58F,LF application, or TC75S58F,LF equivalent, key selection criteria include ultra-low IDD, rail-to-rail compatible input range, open-drain sink capability up to 25 mA at 5 V, propagation delay under 800 ns, and SSOP-5 package compatibility with space-constrained analog sensing and power monitoring designs.
Technical Context
The TC75S58F,LF implements a CMOS-input differential amplifier stage followed by a push-pull output driver configured as an open-drain stage-enabling wired-OR bus configurations and flexible pull-up voltage selection. Its low input bias current (1 pA typ.) and high voltage gain (94 dB) support precision threshold detection without loading high-impedance sources.
Designed for single-supply systems, it accepts input voltages from VSS to VDD − 0.9 V and delivers fast response (tTLH = 170 ns typ. at 3 V), making it suitable for battery-powered comparators, window detectors, and overvoltage/undervoltage monitors where supply current and input range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 10 μA typ. at 3 V - enables multi-year operation in coin-cell–powered sensors |
| Input Offset Voltage | ±1 mV max - ensures accurate 100-mV-level threshold detection without trimming |
| Common-Mode Input Range | VSS to VDD − 0.9 V - supports direct sensing of signals near ground or rail in 3.3 V/5 V systems |
| Sink Output Current | 25 mA max at VOL = 0.5 V (5 V supply) - drives LEDs, MOSFET gates, or logic inputs directly |
| Propagation Delay | 620 ns typ. (TTL step, 5 V) - meets timing requirements for 1-MHz window comparator loops |
| Operating Supply | 1.8 V to 7 V single supply - interoperable across Li-ion, USB, and industrial 5 V rails |
Pinout & Package
TC75S58F,LF is housed in a 5-pin SSOP (Shrink Small Outline Package) with 0.95 mm lead pitch, measuring 2.9 × 2.8 × 1.25 mm and weighing 0.014 g (typ.). The package is RoHS-compliant and optimized for reflow soldering in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference terminal; must be connected before VDD to prevent latch-up |
| 2 | OUT | Open-drain output; requires external pull-up for logic HIGH; sinks up to 25 mA |
| 3 | IN(−) | Inverting input; high-impedance node (1 pA bias current) for feedback or reference connection |
| 4 | IN(+) | Non-inverting input; accepts signals from VSS to VDD − 0.9 V without phase reversal |
| 5 | VDD | Positive supply rail; supports 1.8–7 V; must be stable within ±5 % for specified offset performance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 10 μA typ. at 3 V - extends battery life in portable gas sensors and wearables |
| Wide input common-mode range | VSS to VDD − 0.9 V - eliminates need for level-shifting resistors in 3.3 V microcontroller interfaces |
| Open-drain output architecture | Enables wired-OR logic and mixed-voltage interfacing (e.g., 3.3 V comparator driving 5 V MCU interrupt line) |
| CMOS input stage | 1 pA input bias current - preserves accuracy when used with high-value resistor dividers (>1 MΩ) |
Applications
| Battery Voltage Monitor | Overcurrent Detection |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger cutoff at 2.8 V or 4.2 V thresholds. IC Role / Device Role / Timing Role: Single comparator comparing divided battery voltage against precision reference; open-drain output pulls MCU reset line low on fault. Use Value: 10 μA IDD minimizes quiescent drain; VDD = 3.3 V operation allows direct use of system rail without LDO. | Use Scenario: Detecting shunt voltage rise above 50 mV in motor driver H-bridge to disable gate drive on overcurrent. IC Role / Device Role / Timing Role: High-speed comparator with tPHL = 230 ns (100 mV overdrive) enabling sub-microsecond fault response. Use Value: Rail-to-rail input range captures full shunt swing; 25 mA sink drives optocoupler LED directly. |
| Window Comparator Node | Power Sequencing Supervisor |
Use Scenario: Implementing dual-threshold detection (e.g., 1.2 V < VIN < 3.0 V) using two TC75S58F,LF units in parallel. IC Role / Device Role / Timing Role: One unit monitors lower bound (IN+ tied to reference, IN− to VIN); second monitors upper bound (IN− tied to reference, IN+ to VIN). Use Value: Identical offset and gain specs ensure matched hysteresis; SSOP-5 footprint saves board area vs. SOIC-8 alternatives. | Use Scenario: Validating correct power-up order of 1.2 V core, 3.3 V I/O, and 5 V analog rails in FPGA-based systems. IC Role / Device Role / Timing Role: Each TC75S58F,LF compares its rail to a scaled reference; outputs wire-OR into single "ALL_GOOD" signal. Use Value: Open-drain outputs allow shared pull-up to 3.3 V logic rail; low IDD avoids loading monitored supplies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV331M5X/NOPB | Higher supply current (60 μA typ.), rail-to-rail input, push-pull output (no external pull-up needed) | Better for low-voltage (1.8 V) rail-to-rail input sensing but lacks wired-OR capability | Select when output load requires active HIGH drive and layout cannot accommodate pull-up resistors |
| TLV3701DBVR | Lower offset (±3 mV max), 850 nA IDD, open-drain output, same SSOP-5 package | Superior for nanoamp-bias sensor interfaces but slower (tPLH = 5.5 μs) | Select when ultra-low power (<1 μA) dominates timing requirements and speed >100 kHz is not needed |
Compared with LMV331M5X/NOPB and TLV3701DBVR, the TC75S58F,LF uniquely balances sub-10-μA quiescent current, 620-ns propagation delay, and open-drain flexibility in a compact SSOP-5 package-making it optimal for cost-sensitive, space-constrained, and multi-rail interface applications where both speed and wiring simplicity matter.

FAQ
What is the maximum supply voltage for TC75S58F,LF?
The TC75S58F,LF supports a maximum supply voltage of 7 V on VDD relative to VSS. Absolute maximum ratings specify ±3.5 V for dual-supply operation or up to +7 V for single-supply use. Exceeding 7 V risks permanent damage due to internal CMOS gate oxide breakdown, and operation above this limit voids warranty and reliability guarantees.
Does TC75S58F,LF have rail-to-rail input capability?
The TC75S58F,LF does not provide full rail-to-rail input operation. Its common-mode input voltage range extends from VSS to VDD − 0.9 V, meaning the upper limit falls 0.9 V below VDD. For example, at VDD = 5 V, the maximum valid input is 4.1 V. This limitation must be accounted for when interfacing with signals near the positive rail.
Can TC75S58F,LF drive an LED directly?
Yes, TC75S58F,LF can drive an LED directly via its open-drain output. With a 5 V supply and 5 mA sink current, the output voltage drop is guaranteed ≤0.3 V (VOL), allowing sufficient forward voltage headroom for standard red/green LEDs. A series current-limiting resistor must be used, and total sink current must remain within the 25 mA absolute maximum rating.
Is TC75S58F,LF pin-compatible with TC75S58FU?
No, TC75S58F,LF and TC75S58FU are not pin-compatible. TC75S58F,LF uses the SSOP5-P-0.95 package (0.95 mm pitch), while TC75S58FU uses SSOP5-P-0.65A (0.65 mm pitch). Though both are 5-pin comparators with identical pin functions, their land patterns, solder stencil apertures, and reflow profiles differ significantly-requiring separate PCB footprints.
What is the typical input bias current of TC75S58F,LF?
TC75S58F,LF exhibits a typical input bias current of 1 pA at 25°C, as confirmed in Toshiba's Electrical Characteristics table. This ultra-low value enables high-impedance applications such as photodiode amplification or megohm-scale resistor divider networks without significant error contribution from input loading.
