Description

The M54/74HC4028 is a high speed CMOS BCDTO- DECIMAL DECODER fabricated in silicon gate C2MOStechnology. It has the same highspeed performance of LSTTL combined with true CMOS low power consumption. ABCD 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 fifteen gives a low level at all outputs. The device also can be used as 3-TO- 8-LINE DECODER, when D input is assigned as a disable input. M74HC4028 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.
