TL16C452FNG4

UART 2CH 5V 68Pin PLCC Tube

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
