Product Summary

The TL16C554FN is an asynchronous communications element. Each channel performs serial-to-parallel conversion on data characters of TL16C554FN received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. The complete status of each channel of the TL16C554FN can be read at any time during functional operation by the CPU. The information obtained includes the type and condition of the operation performed and any error conditions encountered.

Parametrics

TL16C554FN absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V; (2)Input voltage range at any input, VI: –0.5 V to 7 V; (3)Output voltage range, VO: –0.5 V to VCC + 3 V; (4)Continuous total power dissipation at (or below) 70℃: 500 mW; (5)Operating free-air temperature range, TA: –0℃ to 70℃; (6)Storage temperature range, Tstg: –65℃ to 150℃.

Features

TL16C554FN features: (1)Integrated Asynchronous Communications Element; (2)Consists of Four Improved TL16C550 ACEs Plus Steering Logic; (3)In FIFO Mode, Each ACE Transmitter and Receiver Is Buffered With 16-Byte FIFO to Reduce the Number of Interrupts to CPU; (4)In TL16C450 Mode, Hold and Shift Registers Eliminate Need for Precise Synchronization Between the CPU and Serial Data; (5)Up to 16-MHz Clock Rate for up to 1-Mbaud Operation.
