74VCX16827
Low Voltage 20-Bit Buffer/Line Driver with 3.6V Tolerant
Inputs and Outputs
General Description
The VCX16827 contains twenty non-inverting buffers with
3-STATE outputs to be employed as a memory and
address driver, clock driver, or bus oriented transmitter/
receiver carrying parity. The device is byte controlled. Each
byte has NOR output enables for maximum control flexibil-
ity.
The 74VCX16827 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O capability up to 3.6V.
The 74VCX16827 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
