Fully Configurable: Inputs and Outputs Track VCC
Non-Preferential Power-Up; Either VCC May Be
Powered Up First
Outputs Remain in 3-State Until Active VCC Level is
Outputs Switch to 3-State if Either VCC is at GND
Bus-Hold on Data Inputs Eliminates the Need for
Control Input (/OE) Referenced to VCCA Voltage

- 2kV CDM (per ESD STM 5.3)
The FXLA104 is a configurable dual-voltage supply
translator for both uni-directional and bi-directional
voltage translation between two logic levels. The device
allows translation between voltages as high as 3.6V to
as low as 1.1V. The A port tracks the VCCA level and the
B port tracks the VCCB level. This allows for bi-directional
voltage translation over a variety of voltage levels: 1.2V,
1.5V, 1.8V, 2.5V, and 3.3V.
The device remains in three-state until both VCCs reach
active levels, allowing either VCC to be powered up first.
Internal power-down control circuits place the device in
3-state if either VCC is removed.
The /OE input, when HIGH, disables both the A and B
ports by placing them in a 3-state condition. The /OE
input is supplied by VCCA.
The FXLA104 supports bi-directional translation without
the need for a direction control pin. The two ports of the
device have auto-direction sense capability. Either port
may sense an input signal and transfer it as an output
signal to the other port.
