Description
The HD74LVCC4245A 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 uses 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 A port, V
CCA
, is dedicated to accept a 5 V supply level, and the configurable B port, which is designed
to track V
CCB
, accepts voltages from 3 V to 5 V. This allows for translation from a 3.3 V to a 5 V
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.
