Toshiba Semiconductor and Storage TC75S70L6X,LF

Overview

TC75S70L6X,LF from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS input/output full-swing comparator optimized for ultra-low-voltage operation (1.3 V to 5.5 V), low quiescent current (18 µA typ. at 1.5 V), and high-density portable applications. It features push-pull output, 1 pA typical input bias current, and operates across –40°C to +85°C.

For engineers reviewing the TC75S70L6X,LF datasheet, TC75S70L6X,LF pinout, TC75S70L6X,LF application, or TC75S70L6X,LF equivalent, key selection criteria include supply voltage range, propagation delay (400 ns L/H at 3.0 V), input offset voltage (±1 mV typ.), and MP6C package compatibility with space-constrained PCB layouts.

Technical Context

The TC75S70L6X,LF implements a rail-to-rail input and output architecture using CMOS process technology, enabling full-swing operation from VSS to VDD. Its push-pull output stage eliminates need for external pull-up resistors and supports direct interfacing with digital logic families including 1.8 V and 3.3 V systems.

Designed for single-supply operation, it maintains stable performance across its 1.3–5.5 V supply range with common-mode input voltage spanning VSS to VDD. Input bias current remains ultra-low (1 pA typ.) across temperature, minimizing errors in high-impedance sensor interface circuits.

FAQ

What is the maximum operating temperature for the TC75S70L6X,LF?

The TC75S70L6X,LF is rated for continuous operation from –40°C to +85°C ambient temperature. Its thermal resistance (junction-to-ambient) is 400°C/W when mounted on an FR4 board, meaning junction temperature remains within safe limits (<125°C) under typical 18 µA supply current and minimal output loading. Always verify PCB copper area and airflow in high-temperature enclosures.

Does the TC75S70L6X,LF require external pull-up resistors on its output?

No, the TC75S70L6X,LF features a push-pull output stage capable of actively driving both high and low logic levels to VDD and GND respectively. This eliminates the need for external pull-up resistors, reducing component count and improving rise/fall time consistency compared to open-drain comparators like the NCS2200SQ2T2G.

Can the TC75S70L6X,LF operate from a 1.5 V alkaline battery?

Yes, the TC75S70L6X,LF supports supply voltages as low as 1.3 V, making it fully functional across the entire discharge curve of a 1.5 V alkaline cell (typically 1.5 V down to ~0.9 V). At 1.5 V, it draws only 6.0 µA typ. supply current and maintains 1 pA input bias current - ideal for long-life battery-powered sensors.

What is the function of Pin 6 (NC) on the TC75S70L6X,LF?

Pin 6 on the TC75S70L6X,LF is a no-connect (NC) terminal with no internal bond wire or circuit connection. Toshiba specifies that this pin must remain unconnected - neither routed nor thermally relieved on the PCB. Leaving Pin 6 floating avoids unintended coupling or mechanical stress on the ultra-small MP6C package.

How does the TC75S70L6X,LF handle input overvoltage conditions?

The TC75S70L6X,LF specifies absolute maximum differential input voltage as ±6.0 V and input voltage range as VSS to VDD. Exceeding these limits risks latch-up due to its CMOS construction. To protect against transients, use series current-limiting resistors (e.g., 10 kΩ) and clamp diodes to VDD/GND - especially in noisy environments like motor-driven wearables.
