MM54HC42 MM74HC42 BCD-to-Decimal Decoder
General Description
This decoder utilizes advanced silicon-gate
CMOS technology Data on the four input pins select one of the 10 outputs corresponding to the value of the BCD number on the inputs An output will go low when selected otherwise it remains high If the input data is not a valid BCD number all outputs will remain high The circuit has high noise immunity and low power consumption usually associated with
CMOS circuitry yet also has speeds comparable to low power Schottky TTL (LS-TTL) circuits and is capable of driving 10 LS-TTL equivalent loads All inputs are protected from damage due to...
