74LCX126
Low Voltage Quad Buffer
with 5V Tolerant Inputs and Outputs
General Description
The LCX126 contains four independent non-inverting buff-
ers with 3-STATE outputs. Each output is disabled when
the associated output-enable (OE) input is LOW. The
inputs tolerate voltages up to 7V allowing the interface of
5V systems to 3V systems.
The 74LCX126 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 VCC specifications provided
s 5.5 ns tPD max (VCC 3.3V), 10 PA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s r24 mA output drive (VCC 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds JEDEC 78 conditions
s ESD performance:
Human body model ! 2000V
Machine model ! 100V
s Leadless Pb-Free DQFN package
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to GND through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
