SEMICONDUCTOR TECHNICAL DATA

CMOS

P SUFFIX

PLASTIC DIP

CASE 711

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.

FN SUFFIX

PLCC PACKAGE

CASE 777

The received word contains seven address bits with the address of the

MC14469 set on seven pins. Therefore, 2 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.

The MC14469 finds application in transmitting data from remote analog–to–

digital converters, remote MPUs, or remote digital transducers to the master

computer or MPU.
