Low Voltage 16-Bit Buffer/Line Driver with Bushold

and 26Ω Series Resistors in Outputs

General Description

Features

■ 5V tolerant control inputs and outputs

The LCXH162244 contains sixteen non-inverting buffers

with 3-STATE outputs designed to be employed as a mem-

ory and address driver, clock driver, or bus oriented trans-

mitter/receiver. The device is nibble controlled. Each nibble

has separate 3-STATE control inputs which can be shorted

together for full 16-bit operation.

■ 2.3V–3.6V V_CCspecifications provided

■ Outputs include equivalent series resistance of 26Ω to

make external termination resistors unnecessary and

reduce overshoot and undershoot

■ Bushold on data inputs eliminates the need for external

pull-up/pull-down resistors

The LCXH162244 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.

■ 5.3 ns t_PDmax (V_CC= 3.0V), 20 µA I_CCmax

In addition, the outputs include equivalent 26Ω (nominal)

series resistors to reduce overshoot and undershoot and

are designed to sink/source up to 12 mA at V_CC= 3.0V.

■ Power down high impedance inputs and outputs

■ ±12 mA output drive (V_CC= 3.0V)

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ ESD performance:

The LCXH162244 is designed for low voltage (2.5V or

3.3V) V_CCapplications with capability of interfacing to a 5V

signal environment.

Human body model > 2000V

The LCXH162244 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

Machine model > 200V
