Description
The HD74LVCC3245A has eight bus transceivers with three state outputs in a 24 pin package. When
(DIR) is high, data flows from the A inputs to the B outputs, and when (DIR) is low, data flows from the B
inputs to the A outputs. A and B bus are separated by making enable input (OE) high level. This 8-bit non-
inverting bus transceiver contains two separate power-supply rails.
And this product has two terminals (V
CCA
, V
CCB
), V
CCA
is connected with control input and A bus side, V
CCB
is
connected with B bus side. V
CCA
and V
CCB
are isolated.
The B port is designed to track V
CCB
, which accepts voltage from 3 V to 5.5 V, and the A port is designed to
track V
CCA
, which operates at 2.3 V to 3.6 V. This allows for translation from a 3.3 V to a 5 V system
environment and vice versa, or from a 2.5 V to a 3.3 V system environment and vice versa. Low voltage
and high speed operation is suitable at the battery drive product (note type personal computer) and low
power consumption extends the life of a battery for long time operation.
