CY74FCT2646AT 具有三态输出和串联输出电阻的八路寄存总线收发器

CY74FCT2646AT 描述

The CY74FCT2646T consists 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-control (DIR) inputs determine the transceiver function. On-chip termination resistors at the outputs reduce system noise caused by reflections, so that the CY74FCT2646T can replace the CY74FCT646T in an existing design.

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.
