HT16D595 Datasheet | Holtek Semiconductor

.DataSheet.co.kr HT16D595 8-Bit Constant Current LED Driver Feature - - Logic supply voltage: 3.3V~5.5V - - 8-channel constant current output - - Channel output current is fixed at 48mA - - Build-in current setting resistor - - High output current accuracy: Variation between chips is less than ±6% - - Up to 25MHz serial interface clock frequency - - Maximum output terminal voltage 17V - - Schmitt trigger input structure - - 16-pin NSOP package General Description The HT16D595 is a high accuracy constant current driver which is specifically designed for LED display applications. The device provides 8-channel stable and constant current outputs for driving LEDs which may have different forward voltage characteristics, VF, due to process variations. munication with the outside world is catered for by including a fully integrated serial interface function, which provides designers with a means of easy munication with external peripheral hardware. In this way, many devices can be cascaded together to drive larger LED displays. Furthermore, with this serial-to-serial or serial-to-parallel structure, the device is very suitable as a replacement for the 74HC595, in applications and related products which include an 8-bit serial input and serial or parallel output. Applications - - LED Display - - Digital clock, thermometer, counter, voltmeter - - Other consumer application Block Diagram OUT0 OUT1 OUT7 Current Setting Resistor OE 8 bit Output Driver 8 LE 8 bit Output Latch 8 SDI CLK...
