HCF4502集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

HCF4502属于集成电路（IC）的缓冲器驱动器接收器收发器。由意法半导体集团制造生产的HCF4502缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。

DESCRIPTION

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.
