| 术语 | tristate buffer |
| 释义 | tristate buffer 三态缓冲器 A buffer that holds 0-bits and 1-bits (as any other buffer) and which is in a high-resistance “off” state when no data is being transferred to or from it. Such buffers are commonly used in microprocessor systems where multiplexed transfers to and from different locations are made on the same “party line” bus. 一种缓冲器，它既可以象普通缓冲器一样保持0位和1位，也可以在无数据发送或接收时保持 高阻抗的“断开”状态。这类缓冲器通常用在微处理机系统中，在同一条“共线”母线上， 同时与不同的位置进行多路发送和接收操作。 |
