74LCX543
Low Voltage Octal Registered Transceiver with
5V Tolerant Inputs and Outputs
General Description
The LCX543 is a non-inverting octal transceiver containing
two sets of D-type registers for temporary storage of data
flowing in either direction. Separate Latch Enable and Out-
put Enable inputs are provided for each register to permit
independent input and output control in either direction of
data flow.
The LCX543 is designed for low voltage (2.5V or 3.3V) V
CC
applications with capability of interfacing to a 5V signal
environment.
The LCX543 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
