The PI74LCX827 is a 10-bit wide non-inverting bus driver providing high-performance bus interface buffering for wide address/data paths or buses carrying parity. The 10-bit buffers have nanded output enables for maximum control flexibility. They are designed for high-capacitance load drive capability, while providing lowcapacitance bus loading at both inputs and outputs. The PI74LCX827 can be driven from either 3.3V or 5.0V devices allowing this device to be used as a translator in a mixed 3.3/5.0V system.
