74VCXH16240
Low Voltage 16-Bit Inverting Buffer/Line Driver
with Bushold
General Description
The VCXH16240 contains sixteen inverting buffers with 3-
STATE outputs to be employed as a memory and address
driver, clock driver, or bus oriented transmitter/receiver.
The device is nibble (4-bit) controlled. Each nibble has sep-
arate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The VCXH16240 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating inputs at a valid logic level.
The 74VCXH16240 is designed for low voltage (1.65V to
3.6V) V
The 74VCXH16240 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
