Overview
The 3512 is an eight channel non-isolated digital I/O board with +5V tolerant 74LCX14 inputs with hysteresis and +3.3V CMOS 74LVTH125 driven outputs. Each I/O line features a series 10 ohm damping and protection resistor and a 4.7K pull up resistor to +3.3V. On power up the outputs are tri-stated, and can then be enabled on a bit by bit basis. Output high drive is 32mA @ 2.0V minimum. Output low drive is 32mA @ 0.8V maximum.
