64-bit THERMAL HEAD DRIVER
S-4622A
The S-4622A is a CMOS thermal print head driver containing a 64-bit shift
register and a latch. It can be used for general purpose because “H” or
“L” can be selected for the latch and the driver enable. It is ideal for the
bar-code printer and the thermal print head of high-speed printing
because of its large driver output current of 70 mA.
