74LVT16245 • 74LVTH16245
Low Voltage 16-Bit Transceiver with 3-STATE Outputs
General Description
The LVT16245 and LVTH16245 contain sixteen non-invert-
ing 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 LVTH16245 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 LVT16245
and LVTH16245 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining 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 (74LVTH16245), also
available without bushold feature (74LVT16245).
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink −32 mA/+64 mA
s Functionally compatible with the 74 series 16245
s Latch-up performance exceeds 500 mA
