IDT74LVC4245A

DESCRIPTION:

The LVC4245A is manufactured using advanced dual metal CMOS

technology. This octal noninverting bus transceiver contains two separate

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.
