These devices are 8-channel, high-voltage switches with 8-bit parallel or serial input control.
They connect directly to a microprocessor through a standard 3-wire serial interface.
MX877 (Data Sheet) The push-pull outputs of the device can drive up to 80mA, and can be paralleled
for increased drive current up to a package total current of 400mA sink or source.
MX879 (Data Sheet) The open-drain, pull-up outputs of the device can drive up to 120mA, and
can be paralleled for increased drive current up to a package total current of 600mA source. |
