Description

These16-bit transceiversare designedfor useinbidirectional synchronous communication between two buses, where high speed and low power are required. Direction of data flow is controlled by (DIR), the Output Enable (OE) transfers data of CY74FCT163H245 when LOW and isolates the buses when HIGH. The outputs of CY74FCT163H245 are 24-mA balanced output drivers with current limiting resistors to reduce the need for external terminating resistors and provide for minimal undershoot and reduced ground bounce..

The CY74FCT163H245 has "bus hold" on the data inputs, which retains the input's last state whenever the input goes to high impedance. This eliminates the need for pull-up/down resistors and prevents floating inputs.

The CY74FCT163245 is designed with inputs and outputs capable of being driven by 5.0V buses, allowing its use in mixed voltage systems as a translator. The outputs of CY74FCT163H245 are also designed with a power off disable feature enabling its use in applications requiring live insertion.
