Description

The TOIM3xxx series ICs provide proper timing for the front end infrared transceiver TFDS3000, as specified by the IrDA standard. In the transmit mode, the TOIM3xxx provides IrDA-compatible electrical pulses to the infrared transceiver TFDS3000 on logic LOW electrical input. In the receive mode, the TOIM3xxx stretches received infrared pulses to the proper bit width at the operating bit rate. The IrDA bit rate varies from 2.4 to 115.2 kbit/s.
