The HCC4529B (extended temperataure range) and HCF4529b (intermediate temperature range) are monolithic integrated circuits available in 16lead dual in line plastic or ceramic package and plastic micropackage. The HCC/HCF4529b is a DUAL 4-CHANNEL or 8CHANNEL device. One of the two possible functions can be selected by a proper input coding. For the single 8-bit mode Z and W output must be tied together.
