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 Bi-
CMOS 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.
s Features
Serial-in and serial-out/parallel-out
Cascade connection allowed
Built-in output malfunctioning preventive circuit
Low current consumption at standby ICC 100µA
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)
s Applications
Driving of the thermal heads
Driving of the relays, LEDs, solenoids, etc.
