Description

The CY74FCT16823T and the CY74FCT162823T 18-bit bus interface registers are designed for use in high-speed, low-power systems needing wide registers and parity. 18-bit operation is achieved by connecting the control lines of the two 9-bit registers. Flow-through pinout and small shrink packaging aids in simplifying board layout.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The CY74FCT16823T is ideally suited for driving high-capacitance loads and low-impedance backplanes.

The CY74FCT162823T has 24-mA balanced output drivers with current limiting resistors in the outputs. This reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The CY74FCT162823T is ideal for driving transmission lines.
