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 addi-
tion to the address received, seven command bits may be received for
general–purpose data or control use.
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.
Supply Voltage Range: 4.5 V to 18 V
Low Quiescent Current: 75 A Maximum @ 5 V, 25°C
Guaranteed Data Rates to 4800 Baud @ 5 V, to 9600 Baud @ 12 V
Receive — Serial to Parallel
Transmit — Parallel to Parallel
Transmit and Receive Simultaneously in Full Duplex
Crystal or Resonator Operation for On–Chip Oscillator
See Application Note AN806A
Chip Complexity: 1200 FETs or 300 Equivalent Gates
Operating Temperature Range TA = –40° to +85°C
