General Description

The MIC4807 is an 80V, 8-channel, addressable low side driver with latches and TTL/CMOS compatible logic inputs. Each logic input is composed of a comparator with a 1.4V bandgap-derived reference serving as the trip point. The addresses (AIN, BIN, and CIN) and Data-in logic inputs have an internal 50µA pull-up current source, while the Output Enable (OE), Chip Select (CS), and Clear logic inputs have an internal 75µA pull-down sink. If the logic lines to the MIC4807 are severed, these currents guarantee that the outputs will turn OFF.
