74LVT162245 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) VCC 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.
Features
s Input and output interface capability to systems at
5V VCC
s Bushold data inputs eliminate the need for external pull-
up resistors to hold unused inputs (74LVTH162245),
also available without bushold feature (74LVT162245).
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s A Port outputs include equivalent series resistance of
25
: making external termination resistors unnecessary
and reducing overshoot and undershoot
s A Port outputs source/sink
r12 mA.
B Port outputs source/sink
32 mA/64 mA
s Functionally compatible with the 74 series 162245
s Latch-up performance exceeds 500 mA
s ESD performance:
