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) VCC 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.
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
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 543
s Latch-up performance exceeds 500 mA

Note 8: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH).
