MX879
8-Channel, 60V Driver with
Open-Drain Output, 3 Wire Interface
Description
The MX879 is an 8-channel, high voltage switch with
8-bit parallel or serial input control. The MX879
connects directly to a microprocessor through a
standard 3-wire serial interface. The open-drain,
pull-up output configuration can drive up to 60 volts at
-120mA. Outputs can be paralleled for increased drive
current up to a device total of 600mA source.
The MX879 is designed to operate over a temperature
range of -40°C to +85°C, and is available in a 28-lead
QFN Package.
