ML14469
Addressable Asynchronous Receiver/Transmitter CMOS
Legacy Device: Motorola MC14469
The ML14469 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 ML14469 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 ML14469 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 may be received for general–purpose data or control use.
