MC14469 Addressable Asynchronous Receiver/Transmitter

A0 * A6 Address Inputs These inputs are the address setting pins which contain the address match for the received signal. Pins A0 * A6 have on *chip pull *up resistors. C0 * C6 Command Word These pins are the readout of the general *purpose command word .

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC14469/D MC14469 Addressable Asynchronous Receiver/Transmitter CMOS The MC14469 receives one or two 11 bit words in a serial data stream. One of the incoming words contains the address and when the address matches, the MC14469 then transmits information in two 11 bit word data streams. Each of the transmitted words contains eight data bits, an even parity bit, and start and stop bits. The received word contains seve.

MC14469 Features

* n at the center of a receive clock period. The start bit is followed by eight data bits. Seven of the bits are compared against states of the address of the particular circuit (A0

* A6). Address is latched 31 clock cycles after the end of the start bit of the incoming address. The eighth bit
