20-bit Buffers/drivers With 3-state Outputs

  The CY74FCT16827T 20-bit Buffer Line Driver and the CY74FCT162827T 20-bit Buffer Line Driver provide high-performance Bus Interface buffering for wide data/address paths or buses carrying parity. These parts can be used as a single 20-bit Buffer or two 10-bit Buffers Each 10-bit Buffer has a pair of NANDed OE for increased flexibility. 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 CY74FCT16827T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The CY74FCT162827T 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 CY74FCT162827T is ideal for driving transmission lines.
