■ FEATURES

— CMOS technology
— TTL input compatibility
— High speed up to 12.5Mbaud(NRZ code)
— Low supply voltage (2.7V ~ 5.5V)
— Low quiescent supply current ( < 1mA )
— Low power consumption
— Uniform output waveform
— Constant current output: ~3mA @VOUT=1V

■ APPLICATIONS

— Digital audio interface including fiber optic inter-connections

■ GENERAL DESCRIPTIONS

The PS071 is a high performance LED driver with low power consumption. It is

primarily designed for applications of 12.5-Mbps plastic fiber optic data

communications with the 650nm or 660nm LED. The TTL interface contains
noise-suppression function and the current through the LED is almost constant

in the operating voltage range in order to ensure precise launch power.
