74VCX16722

Low Voltage 22-Bit Register

with 3.6V Tolerant Inputs and Outputs

General Description

The VCX16722 low voltage 22-bit register contains twenty-

two non-inverting D-type flip-flops with 3-STATE outputs

and is intended for bus oriented applications. The design

has been optimized for use with JEDEC compliant 200 pin

DIMM modules.

The 74VCX16722 is designed for low voltage (1.65V to

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

The 74VCX16722 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

3.6ns max for 3.0V to 3.6V VCC

4.6ns max for 2.3V to 2.7V VCC

9.2ns max for 1.65V to 1.95V VCC

s Power-down high impedance inputs and outputs

s Supports live insertion/withdrawal (Note 1)

s Meets JEDEC registered module specifications

s Static Drive (IOH/IOL)

±24mA @ 3.0V

±18mA @ 2.3V

±6mA @ 1.65V

s Latchup performance exceeds 300 mA

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.
