| Others DN8648FBP 32-bit Shift Register Latch Driver IC s Overview The DN8648FBP is an IC which incorporates a 32-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 32-step shift register block and latch block are composed of CMOS, and the 32-step parallel driver block is bipolar. 33 34 23 22 0.350.1 Unit : mm 44 1 0.10.1 11 12 * Serial-in and serial-out/parallel-out * Cascade connection allowed * Built-in output malfunctioning preventive circuit * Low current consumption at standby ICC 100A * High-breakdown, large current drive type output steps Breakdown voltage : 30V Output current : 120mA (per pin) * Surface mountable 44-pin flat package (pin pitch : 0.8mm) 1.30.1 10.00.3 12.20.3 44-pin QUADFLAT Package (QFH044-P-1010 ) DQ CP + 0.1 s Features 0.8 10.00.3 12.20.3 0.2 - 0.05 1.30.1 0.6 s Applications * Driving of the thermal heads * Driving of the relays, LEDs, solenoids, etc. s Block Diagram SIN CLK 38 DQ CP DQ CP DQ CP DQ CP 39 SOUT 35 STB 36 LD Q LD Q LD Q LD Q 34 LD Q Output malfunction protector VCC EN 37 GND 6, 7, 27, 28 33 32 31 43 42 Q1 Q2 Q3 Q31 Q32 2.850.2 1 DN8648FBP s Absolute Maximum Ratings (Ta = 25C) 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 (Per one circuit) 1.8 * - 20 to + 75 - 55 to + 125 Others Unit V V mA W C C * When mounting onto the PCB, power dissipation is reduced at a rate of 15mW/C from Ta= 25C. s Recommended Operating Range (Ta=25C) Parameter Operating supply voltage Output voltage Output current Clock frequency Input pulse width Setup time Hold time Clock pulse rise time Clock pulse fall time CLK STB SIN STB SIN STB Symbol VCC VO IO fCLK tw tsu th tr tf Range 4 to 6V below 30V below 100mA *1 below 10MHz *2 over 40ns over 40ns over 30ns over 40ns over 20ns over 0ns below 500ns below 500ns *1 An allowable value changes depends on the number of simultaneously turned-on circuits and the duty.
