74LCX32244
Low Voltage 32-Bit Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
The LCX32244 contains thirty-two 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 32-bit operation.
The LCX32244 is designed for low voltage (2.5V or 3.3V)
V_CC applications with capability of interfacing to a 5V signal
environment.
The LCX32244 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V V_CC specifications provided
s 4.5 ns t_PD max (V_CC = 3.0V), 20 µA I_CC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 mA output drive (V_CC = 3.0V)
s Uses patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
s Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
Note 1: To ensure the high-impedance state during power up or down OE
should be tied to V_CC through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
