I'm using LM293, R1 and R2 sets a Vlow and Vhigh threshold, when input is inside Vlow and Vhigh, both leds are off, when input is above or below, one of the leds turns on. This is working ok.
To reduce consumption i changed LM293 by TLV3402, but window comparator does not work anymore. When input is outside window, leds don't turn on.
Both ICs have the same pinout (i use the same circuit, just replace one IC by the other), why TLV3402 does not work? It is not a fault one, i tested with a second one, the same result.
Are these IC the same, or am i missing something?
