Description

These 16-bit buffers/line drivers of CY74FCT162H244T are designed for use in memorydriver,clockdriver,orotherbusinterfaceapplications, where high-speed and low power are required. With flow-through pinout and small shrink packaging board layout is simplified. The three-state controls of CY74FCT162H244T are designed to allow 4-bit, 8-bit or combined 16-bit operation. The outputs are designed with a power-off disable feature to allow for live insertion of boards.

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. This reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The CY74FCT162244T is ideal for driving transmission lines. TheCY74FCT162H244Tisa24-mAbalancedoutputpartthat has "bus hold" on the data inputs. The device retains the in- put's last state whenever the input goes to high impedance. This eliminates the need for pull-up/down resistors and prevents floating inputs.
