This octal noninverting bus transceiver contains two separate supply rails B port has VCCB, which is set at 3.3V, and A port has VCCA, which is set at 5V. This allows for translation from a 3.3V to a 5V environment, and vice-versa. This device is ideal for asynchronous communication between two buses A and B . The direction control pin DIR controls the direction of data flow. The output enable pin OE overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. The LVC4245A has been designed with a ±24mA output driver.

DESCRIPTION:

The LVC4245A is manufactured using advanced dual metal CMOS technology. This octal noninverting bus transceiver contains two separate supply rails B port has VCCB, which is set at 3.3V, and A port has VCCA, which is set at 5V. This allows for translation from a 3.3V to a 5V environment, and vice-versa.

This device is ideal for asynchronous communication between two buses A and B . The direction control pin DIR controls the direction of data flow. The output enable pin OE overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin.

The LVC4245A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance.

APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
