HD74LVC4245A

• This product function as level shift transceiver that change V_CCA input level to V_CCB output level, V_CCB input level to 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 = 4.5 V to 5.5 V, V_CCB = 2.7 V to 3.6 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) = 3.6 V (@V_CCB = 0 V or output off state)
• High output current A bus side : ±24 mA (@V_CCA = 4.5 V to 5.5 V)
                                   B bus side : ±12 mA (@V_CCB = 2.7 V)
                                                       ±24 mA (@V_CCB = 3.0 V to 3.6 V)
• Ordering Information

The HD74LVC4245A 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. And this product has two terminals (V_CCA, V_CCB), V_CCA (5V) is connected with control input and A bus side, V_CCB (3.3V) connected with B bus side. V_CCA and V_CCB are isolated. HD74LVC4245A 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.
