74LVTH32245
Low Voltage 32-Bit Transceiver with 3-STATE Outputs
General Description
The LVT32245 and LVTH32245 contain thirty-two non-
inverting bidirectional buffers with 3-STATE outputs and are
intended for bus oriented applications. The devices are
byte controlled. Each byte has separate control inputs
which can be shorted together for full 32-bit operation. The
T/R inputs determine the direction of data flow through the
device. The OE inputs disable both the A and B ports by
placing them in a high impedance state.
The LVTH32245 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These non-inverting transceivers are designed for low volt-
age (3.3V) V

applications, but with the capability to pro-
vide a TTL interface to a 5V environment. The LVT32245
and LVTH32245 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
