Description
The HD74ALVC165245A has 16 bus transceivers with three state outputs in a 48-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 16-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 A bus side, V_CCB is connected
with control input and B bus. V_CCA and V_CCB are isolated.
The A port is designed to track V_CCA, which accepts voltages from 1.4 V to 3.6 V, and the B port is
designed to track V_CCB, which operates at 1.2 V to 2.7 V. Therefore, Bidirectional broad voltage
conversion is possible.
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.
