DS8874 9-Digit Shift Input LED Driver
General Description
The DS8874 is a 9-digit LED driver which incorporates a
shift register input decoding circuit and a low battery indica-
tor Outputs will sink 110 mA at less than 0 5V drop when
sequentially selected When the V_CC supply falls below 6 5V
typical segment current will be furnished at digit 9 time to
indicate a low battery condition Pin 13 is generally connect-
ed to the decimal point segment on the display so that when
a low battery condition exists the left-most decimal point
lights up
