DN8643S

DN8643S 24-bit Shift Register Latch Driver IC s Overview The DN8643S is an IC which incorporates a 24-bit shift register and a latch driver to meet high-speed operation, low power consumption and high-density printout of the thermal printers for the work processors, and so on. It employs the BiCMOS process in which the serial-in and serial-out/parallel-out functions are incorporated, the 24-step shift register block and latch block are composed of CMOS, and the 24-step parallel driver block is bipolar. 1 0.35±0.25 36 Unit : mm s Features Serial-in and serial-out/parallel-out Cascade connection allowed Built-in output malfunctioning preventive circuit Low current at stanby ICC=≤100µA High-breakdown, large current drive type output steps Breakdown : 30V Output current : 120mA Surface mountable USONF-36D package (pin pitch : 0.8mm) 0.1±0.1 18 19 1.3±0.25 2.85±0.2 0.2 – 0.05 20 36 L D Q Output Malfunction Protector + 0.1 0.5 15.2±0.3 8.4±0.3 11.93±0.3 1.3±0.25 D Q CP s Block Diagram SIN 17 D Q CP D Q CP D Q CP D Q CP 0.8 36-pin PANAFLAT Plastic Package (SSOP036-P-0450) SOUT CLK STB 18 19 L D Q L D Q L D Q L D Q VCC EN 1 GND 8, 9, 10 27, 28, 29 16 15 14 22 21 Q1 Q2 Q3 Q23 Q24 s Absolute Maximum Ratings (Ta=25˚C) Parameter Supply voltage Output voltage Output current Power dissipation Operating ambient temperature Storage temperature Symbol VCC VO IO PD Topr Tstg Rating 0 to 7 0 to 30 120 1.3 * –20 to + 75 –55 to + 125 Unit V V mA W ˚C ˚C * W...
