Low Voltage 32-Bit Buffer/Line Driver
with 3-STATE Outputs (Preliminary)
General Description
The LVT32244 and LVTH32244 contain thirty-two non-
inverting buffers with 3-STATE outputs designed to be
employed as a memory and address driver, clock driver, or
bus oriented transmitter/receiver. The device is nibble con-
trolled. Individual 3-STATE control inputs can be shorted
together for 8-bit, 16-bit, or 32-bit operation.
The LVTH32244 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These buffers and line drivers are designed for low-voltage
(3.3V) V
TTL interface to a 5V environment. The LVT32244 and
LVTH32244 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining a low power dissipation
