74ALVC16821

Low Voltage 20-Bit D-Type Flip-Flops

with 3.6V Tolerant Inputs and Outputs

General Description

The ALVC16821 contains twenty non-inverting D-type

flip-flops with 3-STATE outputs and is intended for bus ori-

ented applications.

The 74ALVC16821 is designed for low voltage (1.65V to

3.6V) VCC applications with I/O compatibility up to 3.6V.

The 74ALVC16821 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

s 1.65V–3.6V VCC supply operation

s 3.6V tolerant inputs and outputs

s tPD

4.0 ns max for 3.0V to 3.6V VCC

4.9 ns max for 2.3V to 2.7V VCC

8.8 ns max for 1.65V to 1.95V VCC

s Power-off high impedance inputs and outputs

s Supports live insertion and withdrawal (Note 1)

s Uses patented noise/EMI reduction circuitry

s Latchup conforms to JEDEC JED78

s ESD performance:

Human body model > 2000V

Machine model > 200V

Note 1: To ensure the high-impedance state during power up or power

down, OE should be tied to VCC through a pull-up resistor; the minimum

value of the resistor is determined by the current-sourcing capability of the

driver.
