... The rail-to-rail output swing enables direct connection of the comparator to both CMOS and TTL logic circuits. The latch input of the EL5285C can be used to hold the comparator output value by applying a low logic level to the pin. The EL5285C features two separate comparators The EL5285C is available in the 14-pin SO package and is specified for operation over the full -40° ...
