UM82C451

The UM82C088 is an enhanced version of the popular UM82c2450 asynchronous communications element(ACE).It provides the user with a fully bidirectional parallel data port that fully supports the paraliel centronics type printer,this port allows information received from either serial communication port to be printed from the P/ACE.

Features of the UM82C088 are:(1)IBM PC/AT compatible;(2)independent control of transmit,receive,line status and data set interrupts;(3)individual modern control signals;(4)three-state TTL drive for the data and control bus.

The absolute maximum ratings of the UM82C088 can be summarized as:(1)ambient operating temperature:-10 to +70;(2)storage temperature:-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.
