UM82C452

The UM82C452 is an enhanced dual channel version of the popular UM82C450 asynchronous communication element(ACE).It services two serial input/output interfaces simultaneously in microcomputer or microprocessor based systems.

Features of the UM82C452 are:(1)IBM PC/AT compatible;(2)centroncis printer interface;(3)independent control of transmit,receive,line status and modem status interrupts on each channel;(4)three-state TTL drive capabilities for bidirectional data bus and control bus for each channel.

The absolute maximum ratings of the UM82C452 can be summarized as:(1)ambient operating temperature:-10 to +70;(2)storage temperture:-65 to +150;(3)supply voltage to ground potential:-0.5V to VCC+0.3V;(4)applied output voltage:-0.5V to VCC+0.3V;(5)applied input voltage:-0.5V to +7.0V;(6)power dissipation:500mW.
