Note:
1. To ensure the high impedance state during power up
and power down, OE
n
should be tied to V
CC
through a
pull up resistor. The minimum value of the resistor is
determined by the current sourcing capability of the
driver.
General Description
The ALVC245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus
oriented 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 74ALVC245 is designed for low voltage (1.65V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74ALVC245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.
