74LVT162245 鈥?74LVTH162245
Low Voltage 16-Bit Transceiver with 3-STATE Outputs
and 25: Series Resistors in A Port Outputs
General Description
The LVT162245 and LVTH162245 contains sixteen non-
inverting bidirectional buffers with 3-STATE outputs and is
intended for bus oriented applications. The device is byte
controlled. Each byte has separate control inputs which
can be shorted together for full 16-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 LVT162245 and LVTH162245 are designed with
equivalent 25
:
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 LVTH162245 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
CC
applications, but with the capability to pro-
vide a TTL interface to a 5V environment. The LVT162245
and LVTH162245 are fabricated with an advanced
BiCMOS technology to achieve high speed operation simi-
lar to 5V ABT while maintaining a low power dissipation.
