MIC4807
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 (A IN , B IN , and C IN ) and Data-in logic inputs have an
internal 50 μ A pull-up current source, while the Output Enable
(OE), Chip Select (CS), and Clear logic inputs have an
internal 75 μ A pull-down sink. If the logic lines to the MIC4807
are severed, these currents guarantee that the outputs will
turn OFF.

? Display Drivers
Individual latches in the MIC4807 are selected by a binary
address presented at inputs A IN , B IN , and C IN . Data-in is
directed to the addressed latch while CS is held low, allowing
an individual output to be pulse-width modulated. When CS
is set high again, the last Data-in is stored in the latch. If Data-
in = "1", the addressed output is turned on, and if Data-in = "0",
the addressed output is turned off.
Information presented to Data-in and the address inputs is
transferred to the latches while CS is pulled low. For
application, where several outputs must be (Continued)
