FT629 - Switch Detection Chip

General Description

The FT629 is a switch detection chip.

It will detect a change on any of its five input pins and send one byte out of the TX pin.

The output byte’s lower five bits correspond to the state of the input pins 1-5.

FT629 ‘Otter’ Switch Detection Chip General Description: The FT629 is a switch detection chip. It will detect a change on any of its five input pins and send one byte out of the TX pin. The output byte’s lower five bits correspond to the state of the input pins 1-5. Figure 1: FT629 pin out www.DataSheet4U.com Operation: The operation of the FT629 is very simple. It will transmit one byte each time there is a change on one of its input pins. There is some debouncing built into the FT629. It will detect a change on the input pins and then send out one byte. Therefore, there will be a 4.16 ms delay after a change is detected before it will check for another pin change.
