intended for bus oriented applications. The device is byte
controlled. Each byte has separate control inputs which
can be shorted together for full 32-bit operation. The T/R

placing them in a high impedance state.

series resistance in both the HIGH and
LOW states on the A Port outputs. This design reduces line
noise in applications such as memory address drivers,
clock drivers, and bus transceivers/transmitters.
The LVTH322245 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
LVT322245 and LVTH322245 are fabricated with an
advanced BiCMOS technology to achieve high speed
operation similar to 5V ABT while maintaining a low power
dissipation.
