74ALVCH16244

Low Voltage 16-Bit Buffer/Line Driver with Bushold

General Description

Features

The ALVCH16244 contains sixteen 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 nibble (4-bit) controlled. Each nibble

has separate 3-STATE control inputs which can be shorted

together for full 16-bit operation.

■ 1.65V to 3.6V V_CCsupply operation

■ 3.6V tolerant control inputs and outputs

■ Bushold on data inputs eliminating the need for external

pull-up/pull-down resistors

■ t_PD

The ALVCH16244 data inputs include active bushold cir-

cuitry, eliminating the need for external pull-up resistors to

hold unused or floating data inputs at a valid logic level.

3 ns max for 3.0V to 3.6V V_CC

3.7 ns max for 2.3V to 2.7V V_CC

6.0 ns max for 1.65V to 1.95V V_CC

The 74ALVCH16244 is designed for low voltage (1.65V to

3.6V) V_CCapplications with output capability up to 3.6V.

■ Uses patented noise/EMI reduction circuitry

■ Latch-up conforms to JEDEC JED78

■ ESD performance:

The 74ALVCH16244 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Human body model > 2000V

Machine model > 200V
