DESCRIPTION
High speed latch and decode operation 120 times as fast as standard CMOS 4511B while CMOS low power consumption in maintained. 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.
