Description

The M54/74HC4543 is a high speed CMOS BCDTO- 7 SEGMENT DECODER WITH LCD DRIVER fabricated in silicon gate C2MOS technology. High speed latch and decode operation 120 times as fast as standard CMOS 4511B while CMOS low power consumption in maintained. M54/74HC4543 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 isblanked.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.
