说明

These 16-bit buffers/line drivers are designed for use in memory driver, clock driver, or other bus interface applications, where high-speed and low power are required. With flow-through pinout and small shrink packaging board layout is simplified. The three-state controls are designed to allow 4-bit, 8-bit or combined 16-bit operation.

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

The CY74FCT16244T is ideally suited for driving high-capacitance loads and low-impedance backplanes.

The CY74FCT162244T has 24-mA balanced output drivers with current limiting resistors in the outputs.
