Toshiba Semiconductor and Storage TC75W59FK(TE85L,F)

Overview

TC75W59FK(TE85L,F) from Toshiba is a CMOS dual comparator IC with open-drain outputs, single-supply operation (1.8–7.0 V), 200 μA typical supply current, and propagation delay as low as 60 ns (tPHL at 5 V). It operates across −40°C 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 TC75W59FK(TE85L,F) datasheet, TC75W59FK(TE85L,F) pinout, TC75W59FK(TE85L,F) application, or TC75W59FK(TE85L,F) equivalent, key selection criteria include open-drain output compatibility, rail-to-rail input range (VSS to VDD−0.9 V), low input bias current (1 pA), and SSOP-8 (0.50 mm pitch) package constraints.

Technical Context

The TC75W59FK(TE85L,F) integrates two independent high-precision comparators on a single silicon monolithic die using Toshiba's CMOS process. Each channel features matched input offset voltage (±1 mV typ.), ultra-low input bias current (1 pA), and supports wired-OR logic via open-drain outputs.

It delivers fast response times-tTHL = 3 ns at 100 mV overdrive-and maintains stable operation across 1.8–7.0 V supply, with common-mode input range extending from VSS to VDD−0.9 V. No internal hysteresis or reference is integrated; external configuration determines threshold behavior.

FAQ

What is the maximum operating supply voltage for TC75W59FK(TE85L,F)?

The TC75W59FK(TE85L,F) supports a maximum supply voltage of 7.0 V under normal operation, with absolute maximum rating at ±3.5 V differential or 7 V total across VDD–VSS. Exceeding 7.0 V risks permanent damage due to gate oxide stress in the CMOS input stage. Always maintain VDD ≤ 7.0 V and ensure transient spikes are clamped within this limit using TVS diodes or RC filtering.

Does TC75W59FK(TE85L,F) have internal hysteresis?

No, the TC75W59FK(TE85L,F) does not include internal hysteresis. Its input stage is a basic CMOS differential pair with no built-in positive feedback. Hysteresis must be added externally using resistor feedback from output to non-inverting input. This design allows full flexibility in setting threshold windows and noise immunity levels tailored to each application's signal characteristics.

Can TC75W59FK(TE85L,F) operate from a 1.8 V supply?

Yes, the TC75W59FK(TE85L,F) is fully specified down to 1.8 V supply voltage, with guaranteed performance including 400 μA max supply current and 18 mA sink current at VDD = 3 V. At 1.8 V, it maintains functional operation but with reduced output drive strength and increased propagation delay; verify timing margins in actual circuit conditions using the 3 V electrical characteristics table as a conservative proxy.

What is the package type and lead pitch of TC75W59FK(TE85L,F)?

The TC75W59FK(TE85L,F) uses the SSOP8-P-0.50A package: an 8-pin shrink small outline package with 0.50 mm lead pitch, 2.9 mm width, and 3.0 mm length. This JEDEC-standard footprint is compatible with standard SSOP-8 reflow profiles and supports automated optical inspection (AOI) due to its defined land pattern and gull-wing lead geometry.

Is TC75W59FK(TE85L,F) RoHS compliant?

Yes, TC75W59FK(TE85L,F) meets RoHS Directive 2011/65/EU requirements, with lead-free terminations and halogen-free molding compound. Toshiba confirms compliance in its official environmental documentation, and the part carries the "EU RoHS Compliant" marking on packaging labels.
