74VCXH2245
Low Voltage Bidirectional Transceiver with Bushold
and 26 Series Resistors in B Outputs
General Description
The VCXH2245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus ori-
ented applications. The T/R input determines the direction
of data flow. The OE input disables both the A and B Ports
by placing them in a high impedance state. The VCXH2245
data inputs include active bushold circuitry, eliminating the
need for external pull-up resistors to hold unused or float-
ing data inputs at a valid logic level.
The 74VCXH2245 is designed for low voltage (1.65V to
3.6V) V
with 26
design reduces line noise in applications such as memory
address drivers, clock drivers, and bus transceivers trans-
mitters
The 74VCXH2245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.
