For other types of readouts, such as This device consists of BCD-TO-7 segment light-emitting diode (LED), some additional decoder with a BCD input latch and a 7-segment drivers, such as a transistor array is required. All driver for a liquid crystal display (LCD). When any inputs are equipped with protection circuits illegal BCD input signal is applied or input BI is against static discharge and transient excess held high, the display is blanked. When driving voltage. PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/10
