74LCX16821
Low Voltage 20-Bit D-Type Flip-Flop with 5V Tolerant
Inputs and Outputs
General Description
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
5V signal environment.
The LCX16821 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 6.2 ns tPD max (VCC = 3.3V), 20 A ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s
±24 mA output drive (V
CC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s 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 VCC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
