74VCX162827

Low Voltage 20-Bit Buffer/Line Driver with 3.6V Tolerant

Inputs and Outputs and 26Ω Series Resistors in the

Outputs

General Description

The VCX162827 contains twenty non-inverting buffers with

Features

■ 1.65V–3.6V V_CCsupply operation

3-STATE outputs to be employed as

a memory and

■ 3.6V tolerant inputs and outputs

■ 26Ω series resistors in outputs

■ t_PD

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 74VCX162827 is designed for low voltage (1.65V to

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

3.4 ns max for 3.0V to 3.6V V_CC

4.1 ns max for 2.3V to 2.7V V_CC

8.2 ns max for 1.65V to 1.95V V_CC

VCX162827 is also designed with 26Ω resistors in the out-

puts.

■ Power-off high impedance inputs and outputs

■ Supports live insertion and withdrawal (Note 1)

The 74VCX162827 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

■ Static Drive (I_OH/I_OL

)

±12 mA @ 3.0V V_CC

±8 mA @ 2.3V V_CC

±3 mA @ 1.65V V_CC

■ Uses patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 300 mA

■ 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 V

through a pull-up resistor; the minimum

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

driver.
