description
●The TL16C451 and TL16C452 provide single- and dual-channel (respectively) serial interfaces along with a
●single Centronix-type parallel-port interface. The serial interfaces provide a serial-to-parallel conversion for data received from a peripheral device or modem and a parallel-to-serial conversion for data transmitted by a CPU. The parallel interface provides a bidirectional parallel data port that fully conforms to the requirements for a Centronix-type printer interface.
●Integrates Most Communications CardC Functions From the IBM PC/AT or Compatibles With Single- or Dual-Channel Serial Ports
●TL16C451 Consists of One TL16C450 Plus Centronix Printer Interface
●TL16C452 Consists of Two TL16C450s Plus a Centronix-Type Printer Interface
●Fully Programmable Serial Interface Characteristics:
● – 5-, 6-, 7-, or 8-Bit Characters
● – Even-, Odd-, or No-Parity Bit Generation and Detection
● – 1-, 1 1/2-, or 2 Stop-Bit Generation
● – Programmable Baud Rate(dc to 256 kbit/s)
●Fully Double Buffered for Reliable Asynchronous Operation
