16-bit Buffers/drivers With Bus-hold And 3-state Outputs

  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 ?ow-through pinout and small shrink packaging board layout is simpli?ed. The three-state controls are designed to allow 4-bit, 8-bit or combined 16-bit operation. This device is fully speci?ed for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current back?ow 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. 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. The CY74FCT162H244T is a 24-mA balanced output part that has ?bus hold? on the data inputs. The device retains the input?s last state whenever the input goes to high impedance. This eliminates the need for pull-up/down Resistors and prevents ?oating inputs.
