LC7958NC
64-Bit LED Driver for 300 dpi Printers
Preliminary
Overview
LC7958NC is a 64-bit constant current LED driver IC
designed to directly drive LED head array.
The output terminals for LED drive are arranged in
2-row staggered position of 80-µm pitch at one side. It
enables drive of LED Array of 300-dpi in one side
disposition, 600dpi in both sides disposition
Features and Functions
Logic voltage (VDD): +5 V ± 10 %
LED drive current (IOH): 5.0 mA (TYP)
Clock frequency (fc): 10 MHz
Output current control circuit built in
Mode switching function by the SEL pin
Chip size: 1.43 mm × 5.39 mm
Number of pads: 86
64-bit shift register circuit
64-bit latch circuit
Output driver on/off switching function
Constant current circuit
64-bit p-channel open drain LED driver
