Low Voltage Quad Buffer with 5V Tolerant
Inputs and Outputs
Features
5V tolerant inputs and outputs
2.3V–3.6V V
specifications provided
CC
5.5ns t
max. (V
3.3V), 10µA I
PD
CC
Power down high impedance inputs and outputs
Supports live insertion/withdrawal
±24mA output drive (V
3.0V)
CC
Implements patented noise/EMI reduction circuitry
Latch-up performance exceeds JEDEC 78 conditions
ESD performance:
– Human body model
2000V
– Machine model

Leadless DQFN package
Note:
1. To ensure the high-impedance state during power up
or down, OE should be tied to V
resistor: the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.

General Description
The LCX126 contains four independent non-inverting
buffers with 3-STATE outputs. Each output is disabled
when the associated output-enable (OE) input is LOW.
