6V at VCC = 5V,TA = 25°C DESCRIPTION: The FCT16827AT/BT/CT/ET and FCT162827AT/BT/CT/ ET 20-bit buffers are built using advanced dual metal CMOS technology.
These 20-bit bus drivers provide high-performance bus interface buffering for wide data/address paths or busses carrying parity.
Two pair of NAND-ed output enable controls offer maximum control flexibility and are organized to operate the device as two 10-bit buffers or one 20-bit buffer.
Flow-through organization of signal pins simplifies layout.
All inputs are designed with hysteresis for improved noise margin.
The FCT16827AT/BT/CT/ET are ideally suited for driving high capacitance loads and low impedance backplanes.
The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers.
The FCT162827AT/BT/CT/ET have balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output fall times–reducing the need for external series terminating resistors.
