IDT74ALVC164245
CMOS 16-BIT 3.3V
TO 5V LEVEL SHIFTING
TRANSCEIVER WITH
3-STATE OUTPUTS
DESCRIPTION:
This 16-bit 3.3V to 5V level shifting transceiver is manufactured using
advanced dual metal CMOS technology. The ALVC164245 contains two
separate supply rails; B port has VCCB, which is set at 5V, and A port has
VCCA, which is set to operate at 3.3V. This allows for translation from a 3.3V
to 5V environment and vice-versa. This device is designed for asynchro-
nous communication between data buses.
The ALVC164245 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
