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 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 100V
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.

Note 6: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH).
