DN8643S
24-bit Shift Register Latch Driver IC
s Overview
The DN8643S is an IC which incorporates a 24-bit shift reg-
ister 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 24-step shift register block and
latch block are composed of CMOS, and the 24-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 at stanby ICC=100µA
