CY74FCT646AT 具有三态输出的八路总线寄存收发器

CY74FCT646AT 描述

The \x92FCT646T devices consist of a bus transceiver circuit with 3-state, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus is clocked into the registers as the appropriate clock pin goes to a high logic level. Output-enable (G\) and direction (DIR) inputs control the transceiver function. In the transceiver mode,data present at the high-impedance port can be stored in either the A or B register, or in both. Select controls (SAB, SBA) can multiplex stored and real-time (transparent mode) data. DIR determines which bus receives data when G\ is low. In the isolation mode (G\ is high), A data can be stored in the B register and/or B data can be stored in the A register.
