The FXLH1T45 is a single bit configurable dual-voltage supply
translator designed 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 3-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 Transmit/Receive (T/R)
input determines the direction of data flow through the device. The FXLH1T45 is
designed so that the control pin (T/R)
is supplied by VCCA
