Low Voltage 16-Bit Registered Transceiver
with 3-STATE Outputs
General Description
The
data flowing in either direction. Separate Latch Enable and
Output Enable inputs are provided for each register to per-
mit independent control of inputting and outputting in either
direction of data flow. Each byte has separate control
inputs, which can be shorted together for full 16-bit opera-
tion.
The LVTH16543 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These transceivers are designed for low-voltage (3.3V)
V
interface to a 5V environment. The LVT16543 and
LVTH16543 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining low power dissipation.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
