146818是一种在许多微计算机系统中十分有用的器件,该器件可用的实时时钟频率范围广泛,并含有由时钟维持工作的50字节RAM。它设计来多路转接数据和地址总线,在第一个读或写周期可自动地响应M6805总线或Intel8085总线。 146818是一种静态器件,它对读或写周期的定时没有上限限制。所以,使用该器件最适 The 146818 is a very useful device in many microcomputer systems. It has a wide range of real-time clock frequencies available and contains 50 bytes of RAM that are clocked to work. It is designed to multiplex data and address buses and respond automatically to the M6805 bus or the Intel8085 bus for the first read or write cycle. 146818 is a static device that has no cap on the timing of read or write cycles. Therefore, the best use of the device
