TIR1000 (ACTIVE)

Standalone IrDA Encoder & Decoder

 

Description

The TIR1000x serial infrared (SIR) encoder and decoder is a CMOS device that encodes and decodes bit data in conformance with the IrDA specification.

A transceiver device is needed to interface to the photo-sensitive diode (PIN) and the light emitting diode (LED). A UART is needed to interface to the serial data lines.

Features

  • Adds Infrared (IR) Port to Universal Asynchronous
    Receiver Transmitter (UART)
  • Compatible With Infrared Data Association
    (IrDA™) and Hewlett Packard Serial Infrared
    (HPSIR)
  • Provides 1200-bps to 115-kbps Data Rate
  • Operates from 2.7 V to 5.5 V
  • Provides Simple Interface With UART
  • Decodes Negative or Positive Pulses
  • Available in Two 8-Terminal Plastic Small Outline
    Packages (PSOP)
    • PS Package Has Slightly Larger Dimensions
      Than PW Package
