74LVTH543 Low Voltage Octal Registered Transceiver with 3-STATE Outputs
April 2000
Revised April 2000
74LVTH543
Low Voltage Octal Registered Transceiver
with 3-STATE Outputs
General Description
The LVTH543 octal transceiver contains two sets of D-type
latches for temporary storage of data flowing in either
direction. Separate Latch Enable and Output Enable inputs
are provided for each register to permit independent con-
trol of inputting and outputting in either direction of data
flow.
The LVTH543 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
This octal registered transceiver is 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 LVTH543 is
fabricated with an advanced BiCMOS technology to
achieve high speed operation similar to 5V ABT while
maintaining a low power dissipation.
