74LVT32245 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
CC
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.
Features
a73 Input and output interface capability to systems at
5V V
CC
a73 Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs (74LVTH32245),
also available without bushold feature (74LVT32245).
a73 Live insertion/extraction permitted
a73 Power Up/Down high impedance provides glitch-free
bus loading
a73 Outputs source/sink −32 mA/+64 mA
a73 ESD performance:
Human-body model > 2000V
Machine model > 200V
Charged-device model > 1000V
a73 Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
Ordering Code:
Note 1: Ordering code “G” indicates Trays.
Note 2: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
