74LCX16821  
Low Voltage 20-Bit D-Type Flip-Flop with 5V Tolerant  
Inputs and Outputs  
General Description  
Features  
5V tolerant inputs and outputs  
The LCX16821 contains twenty non-inverting D-type flip-  
flops with 3-STATE outputs and is intended for bus oriented  
applications. The device is designed for low voltage (2.5V  
or 3.3V) VCC applications with capability of interfacing to a  
2.3V–3.6V VCC specifications provided  
6.2 ns tPD max (VCC = 3.3V), 20 µA ICC max  
Power down high impedance inputs and outputs  
Supports live insertion/withdrawal (Note 1)  
±24 mA output drive (VCC = 3.0V)  
5V signal environment.  
The LCX16821 is fabricated with an advanced CMOS tech-  
nology to achieve high speed operation while maintaining  
CMOS low power dissipation.  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds 500 mA  
ESD performance:  
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.
