HD74LVCC3245A

• This product function as level shift transceiver that change V_CCA input level to V_CCB output level, V_CCB input level V_CCA output level by providing different supply voltage to V_CCA and V_CCB.
• This product is able to the power management : Turn on and off the supply on V_CCB side with providing the supply of V_CCA (Enable input (OE) : High level)
• V_CCA = 2.3 V to 3.6 V, V_CCB = 3.0 V to 5.5 V
• All control input VI (max) = 5.5 V (@V_CCA = 0 V to 5.5 V)
• All A bus side input outputs VI/O (max) = 5.5 V (@V_CCA = 0 V or output off state)
• All B bus side input outputs VI/O (max) = 5.5 V (@V_CCB = 0 V or output off state)
• High output current A bus side:
±8 mA (@V_CCA = 2.3 V)
±12 mA (@V_CCA = 2.7 V)
±24 mA (@V_CCA = 3.0 V)
B bus side: ±24 mA (@V_CCB = 3.0 V)

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) of HD74LVCC3245A  high level. This  HD74LVCC3245A 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 of HD74LVCC3245A  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.
