The HCC4502B (extended temperature range) and HCF4502B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF 4502B consists of six inverter-buffers with 3-state outputs. A logic "1" on the OUTPUT DISABLE input produces a highimpedance state in all six outputs. This feature permits common busing of the outputs, thus simplifying system design. A logic "1" on the INHIBIT input switches all six outputs to logic "0" if the OUTPUT DISABLE input is a logic "0". This device is capable of driving two standard TTL loads, which is equivalent to six times the JEDEC "B" series IOL standard.
