74LCX543  
Low Voltage Octal Registered Transceiver with  
5V Tolerant Inputs and Outputs  
General Description  
Features  
5V tolerant inputs and outputs  
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.  
2.3V 3.6V VCC specifications provided  
7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max  
Power down high impedance inputs and outputs  
Supports live insertion/withdrawal (Note 1)  
±24 mA Output Drive (VCC = 3.0V)  
The LCX543 is designed for low voltage (2.5V or 3.3V) VCC  
applications with capability of interfacing to a 5V signal  
environment.  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds 500 mA  
ESD performance:  
The LCX543 is fabricated with an advanced CMOS tech-  
nology to achieve high speed operation while maintaining  
CMOS low power dissipation.  
Human body model > 2000V  
Machine model > 200V  
Note 1: To ensure the high-impedance state during power up or down, OE  
should be tied to V  
through a pull-up resistor: the minimum value or the  
CC  
resistor is determined by the current-sourcing capability of the driver.
