74ALVCH2245
Low Voltage Bidirectional Transceiver with Bushold
and 26
Series Resistors in B Outputs
General Description
The ALVCH2245 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
ALVCH2245 data inputs include active bushold circuitry,
eliminating the need for external pull-up resistors to hold
unused or floating data inputs at a valid logic level.
The 74ALVCH2245 is designed for low voltage (1.65V to
3.6V) V
CC
applications. The ALVCH2245 is also designed
with 26
series resistance in the B Port outputs. This
design reduces line noise in applications such as memory
address drivers, clock drivers, and bus transceivers trans-
mitters
The 74ALVCH2245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.
