ET9600

www.DataSheet4U.com THREE CHANNEL DIFFERENTIAL LINE DRIVER IC With built-in current sink to drive an LED ET9600 FEATURES Supply Voltage Range 4.5V to 30V Operation to 800KHz CMOS and TTL Compatible Inputs Outputs RS-422A Compatible High Impedance Buffered Inputs with Hysteresis Outputs short circuit protected 70mA peak SINK/SOURCE current Outputs Protected by Thermal Shut-Down APPLICATIONS Optical Encoders Industrial Controls DESCRIPTION These line drivers are similar to the four channel 26ET31, with the added feature of providing an internal LED drive. The device is biased so that the base of the LED drive transistor (shown) is held at 2.5V. To set the LED current, connect a resistor from RSET to ground. For more information on LED drive, see application note APP-D2. Voltage connected to the VCC pin is regulated for use by logic functions within the chip, while the output drivers run off this voltage without modification. The device marking (see photo) includes the suffix SCP to denote that this version has ‘short circuit protection’.
