7i42TA - I/O protector (protects FPGA from +12, -7V inputs)

The 7I42 is a breakout card for Mesa's 50 pin I/O FPGA cards. It is available with 50 pin .1" output connector (7I42) or 3.5mm headers compatible with pluggable screw terminal blocks (7I42T and 7I42TA). In addition to providing a breakout function, the 7I42 protects the FPGA card from excessive input voltages and ESD. The 7I42 protects FPGA I/O from accidental contact from external voltages of +12 and -5V with built in diode clamps and 50 Ohm current limit resistors in series with all I/O pins. The 7I42 limits I/O pin bandwidth to approximately 10 MHz. Two TB24 pluggable terminal blocks are required for use with the 7I42T (not included). Phoenix compatible 3.5 mm pluggable screw terminals are supplied with the 7I42TA
