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, 2⁷or 128 units can be

interconnected in simplex or full–duplex data transmission. In addi-

tion to the address received, seven command bits may be received for

general–purpose data or control use.

CASE 711

The ML14469 finds application in transmitting data from remote

analog–to–digital converters, remote MPUs, or remote digital trans-

ducers to the master computer or MPU.
