74ALVC162827

Low Voltage 20-Bit Buffer/Line Driver

with 3.6V Tolerant Inputs and Outputs

and 26Ω Series Resistors in the Outputs

General Description

The ALVC162827 contains twenty non-inverting buffers

with 3-STATE outputs to be employed as a memory and

address driver, clock driver, or bus oriented transmitter/

receiver. The device is byte controlled. Each byte has NOR

output enables for maximum control flexibility.

The 74ALVC162827 is designed for low voltage (1.65V to

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

ALVC162827 is also designed with 26Ω resistors in the

outputs.

The 74ALVC162827 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

s 1.65V to 3.6V VCC supply operation

s 3.6V tolerant inputs and outputs

s 26Ω series resistors in outputs

s tPD

3.9 ns max for 3.0V to 3.6V VCC

4.6 ns max for 2.3V to 2.7V VCC

8.2 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.
