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 seven address bits with the address of the MC14469 set on seven pins.
Therefore, 27 or 128 units can be interconnected in simplex or full–duplex data transmission.
In addition to the address received, seven command bits ...
