描述
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 (VCCA, VCCB), VCCA (5V) is connected with control input and A bus side, VCCB (3. 3V) connected with B bus side. VCCA and VCCB are isolated. 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.
特性
- This product function as level shift transceiver that change VCCA input level to VCCB output level, VCCB input level to VCCA output level by providing different supply voltage to VCCA and VCCB.
- This product is able to the power management: Turn on and off the supply on VCCB side with providing the supply of VCCA. (Enable input (OE): High level )
- VCCA = 4.5 V to 5.5 V, VCCB = 2.7 V to 3.6 V
- All control input VI (max) = 5.5 V (@VCCA = 0 V to 5.5 V)
- All A bus side input outputs VI/O (max) = 5.5 V (@VCCA = 0 V or output off state)
- All B bus side input outputs VI/O (max) = 3.6 V (@VCCB = 0 V or output off state)
- High output current A bus side : ±24 mA (@VCCA = 4.5 V to 5.5 V) B bus side : ±12 mA (@VCCB = 2.7 V) ±24 mA (@VCCB = 3.0 V to 3.6 V)
