DESCRIPTION

The segment output driver, which is CMOS fabri2 cated in silicon gate C MOS technology, has large IOH capability which enables common cathode Leds to be directly driven. When lamp test (LT) is taken ”L”, all segment outputs will go to ”H”, and when blanking (BI) is taken ”L” and LT is taken ”H” all segment outputs will go to ”L”. These functions operate regardless of other inputs and are used to test the display. Input BI is used to pulse-modulate the brightness of the display. When an error input code (over 10) is applied to the BCD input, all segment outputs will go ”L” (turn off). All inputs are equipped with protection circuits against static discharge and transient excess voltage.
