GENERAL DESCRIPTION
T6505A is designed for LED displays. As an enhancement of its predecessor, T6505A contains a serial buffer and data latches which convert serial input data into parallel output format. At T6505A output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of Vf variations.

FEATURES
• 16 constant-current output channels
• Constant output current range:
   3~45 mA at VDD=3.3V
   3~60 mA at VDD=5V
• Output current accuracy:
   between channels: <±3% (max.), and
   between ICs: <±6% (max.)
• Staggered output delay
• Maximum data clock frequency: 25MHz
• Output current adjusted through an external
   resistor
• Schmitt trigger input
• Fast response of output current, OE (min.):
   200 ns
• 3.0V-5V supply voltage

APPLICATIONs
• LED Display Driver
• Portable Communication Devices
• Handheld Electronics
