DESCRIPTION:
The LVCC3245A is manufactured using advanced dual metal CMOS
technology. This 8-bit (octal) noninverting bus transceiver contains two
separate supply rails. The B port is designed to track VCCB, which accepts
voltages from 3V to 5.5V, and the A port is designed to track VCCA, which
operates at 2.3V to 3.6V. This allows for translation from a 3.3V to a 5V
system environment and vice-versa, or from a 2.5V to a 3.3V system
environment, and vice-versa.
This LVCC3245A is ideal for asynchronous communication between two
data buses (A and B). The device transmits data from A to B or from B to
A, depending on the logic level at the direction-control (DIR) input. The
output-enable (OE) input can be used to disable the device so the buses are
effectively isolated.
The LVCC3245A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
