TFDT4000

Edition January 7, 1996

Integrated Transceiver

Description

The TFDT4000 is an infrared transceiver for data communication systems. The

transceiver is compatible to the IRDA standard and allows data rates up to 115 kbit/sAn

internal AGC (Automatic Gain Control) ensures proper operation under EMI conditions.

The internal IRED driver can be connected by the external current control resistor to an

independent unregulated power supply. This will add more freedom in circuit design and

efficient serial drive capability for external IREDs for high power applications.

Features:

Compatible to IRDA standard

Microcomputer compatible

Fewest external components

Low power consumption

AGC for EMI immunity

Open collector IRED driver

SMD top view and through hole side view

Wide supply voltage range (2.7V...5.5V)

Low Profile (height = 5.6 mm max.)

Package:

Pins, see pg. 7:

1: IRED Anode

2: IRED Cathode

3: Txd (Input)

4: Rxd (Output)

5: NC

6: V_CC(Supply Voltage)

7: SC (Sensitivity Control)

8: Ground

2 stand off pins internally connected to ground.
