Keyboard Encoder Serial Output for up to 56 keys

The KBDSER56 IC is designed to provide a serial ASCII output encoder for keyboards up to 56 keys. The KBDSER56 IC contains all the logic necessary to encode a SPST keyboard switch array up to 7 by 8 in size and provide a serial ASCII output. The output is standard asynchronous format, using 8 bits, ? Asynchronous serial output.\r\n? Fully encodes a key switch array. (up to 7 x 8)\r\n? No external parts required.\r\n? Low power consumption 5 mA typical.\r\n? Supply voltage 2.4 to 5.25 volts.\r\n? All timing internally generated.\r\n? 2 Key rollover.\r\n? On chip row input resistors.\r\n? Intern;
