Single comparator in a 1.45×1.0 mm footprint
The Toshiba TC75S70L6X,LF is a single-element general-purpose comparator with a push-pull output stage, housed in a 6-UFDFN package (1.45×1.0 mm body, 6-MP6C). The 800 ns max propagation delay and 35 µA max quiescent current place it in the low-speed, low-power category — suited for threshold detection, over-voltage/under-voltage monitoring, and level translation rather than high-frequency switching or fast comparator loops.
An 800 ns propagation delay (max) means this comparator cannot track fast PWM edges or serve in a switching regulator's feedback path without significant phase lag. What it does well: debouncing a slow sensor output, generating a reset signal from a voltage monitor, or converting an analog threshold to a digital logic level where the input changes on a millisecond scale.
Supply range and input characteristics
Input bias current is 1 pA max at 3 V, which is negligible for high-impedance sources like a thermistor divider or a pH electrode buffer. Input offset voltage is 6 mV max at 3 V — typical for a general-purpose comparator, but worth noting if the trip point needs better than ±6 mV accuracy without trimming.
The 6-UFDFN package is a small no-lead footprint — the 1.45×1.0 mm body saves board area but requires a fine-pitch solder stencil and X-ray inspection for voiding.
