Product Summary
The MAS9138N 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. The applicatiosn of the MAS9138N are (1)Data communication systems; (2)Adapts asynchronous terminals to synchronous modems; (3)Full or half card PC modems using UART as a data source; (4)Simplifying data multiplexing systems.
Parametrics
MAS9138N absolute maximum ratings: (1)Supply Voltage, VDD: -0.5 to 5.5 V; (2)Storage Temperature, Ts: -55 to +150℃.
Features
MAS9138N features: (1)Implements CCITT recommendation V.14; (2)Bypass operation; (3)Character length from 8 to 11 bits including start stop and parity bits; (4)CMOS and LS-TTL compatible interface; (5)Low power consumption (typically 10 mW); (6)No additional circuitry needed to perform conversion ; (7)Single +3.3 to +5V supply; (8)Operating temperature -40 to 85℃; (9)16-pin PDIP and SO package.
