DESCRIPTION

MAS9138 is a single chip duplex asynchronous to synchronous converter. It converts asynchronous start stop characters to synchronous format, with stop bit deletion when required as defined in the CCITT recommendation V.14. On the receiver channel MAS9138 converts the incoming synchronous data to asynchronous start stop character format with stop bit insertion when required as defined in the CCITT recommendation V.14.

FEATURES

? Implements CCITT recommendation V.14

? Bypass operation

? Character length from 8 to 11 bits including start stop and parity bits

? CMOS and LS-TTL compatible interface

? Low power consumption (typically 10 mW)

? No additional circuitry needed to perform conversion

? Single +3.3...+5V supply

? Operating temperature -40oC to 85oC

? 16-pin PDIP and SO package

APPLICATION

? Data communication systems

? Adapts asynchronous terminals to synchronous modems

? Full or half card PC modems using UART as a data source

? Simplifying data multiplexing systems
