GENERAL DESCRIPTION
The 74LVC2T45 is a 2-bit, dual-supply bus transceiver
with configurable voltage translation. The device has
two separate configurable power-supply rails. The A
and B ports track the VCCA supply and VCCB supply
respectively. The supply voltage pins accept voltage
range from 1.65V to 5.5V, which makes the device
suitable for low voltage bidirectional translation voltage
nodes of 1.8V, 2.5V, 3.3V, and 5V.
The 74LVC2T45 features that two data buses can
communicate asynchronously. Either the A port outputs
or the B port outputs can be activated by DIR logic
levels. The DIR input circuit is supplied by VCCA. When
B port outputs are activated, the device allows the data
to transmit from A bus to B bus. On the contrary, when
A port outputs are activated, the device allows the data
to transmit from B bus to A bus. The input circuit is
always active on the two ports. A logic level of high or
low must be set to avoid excessive supply current.
