CY74FCT2827T
SCCS045 - May 1994 - Revised March 2000
10-Bit Buffer
Functional Description
The FCT2827T 10-bit bus driver provides high-performance
bus interface buffering for wide data/address paths or buses
carrying parity. This 10-bit buffer has NAND-ed output enables for
maximum control flexibility. The FCT2827T is designed for
high-capacitance load drive capability, while providing low-capaci-
tance bus loading at both inputs and outputs. All inputs have clamp
diodes and all outputs are designed for low-capacitance bus loading
in the high impedance state. On-chip termination resistors have
been added to the outputs to reduce system noise caused by re-
flections. The FCT2827T can be used to replace the FCT827T to
reduce noise in an existing design.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
