Comparators FAQ

What is the input common-mode voltage range for the TL3116CD?

The input common-mode voltage includes the negative rail, allowing it to extend down to the negative supply voltage. With a single 5-V supply, the range is 0 V to 2.5 V. With dual ±5-V supplies, the range is -5 V to 2.5 V.

How does the LATCH ENABLE terminal function?

The LATCH ENABLE terminal allows the complementary outputs to be latched. A low-level input voltage (VIL) of 0.8 V enables the latch state, while a high-level input voltage (VIH) of 2 V disables it, allowing normal comparator operation.
