The M54/74HC4028 is a high speed CMOS BCDTO-DECIMAL DECODER fabricated in silicon gate 2 C MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. A BCD code applied to the four inputs (A to D) provides a high level at the selected one of the decimal decoded outputs. An illegal BCD code such as eleven to.
es a low level at all outputs. The device also can be used as 3-TO8-LINE DECODER, when D input is assigned as a disable input. The device is useful for code conversion, address decoding, memory selection, demultiplexing, or read out decoding. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
