The FXL2TD245 is a 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
OE input, when HIGH, disables
both the A and B Ports by placing them in a 3-STATE condition. The FXL2TD245 is
designed so that the control pins (T/R
and OE) are supplied by VCCA.
