DESCRIPTION The M54/74HC4543 is a high speed CMOS BCDTO-7 SEGMENT DECODER WITH LCD DRIVER 2 fabricated in silicon gate C MOS technology. High speed latch and decode operation 120 times as fast as standard CMOS 4511B while CMOS low power consumption in maintained. This device consist of BCD-TO-7 segment decoder with a BCD input latch and a 7-segment driver for a liquid crystal display (LCD). When any illegal BCD input signal is applied or input BI is held high, the display is blanked. When driving LCDs, a common square wave signal should be applied not only to the PH input of this device but also to the electrically common backplane of the display. For other types of readouts, such as light-emitting diode (LED), some additional drivers, such as a transistor array is required. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

(*) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD *VCC *fIN + ICC/2 (per FLIP/FLOP)
