• Manufacturer: Motorola Inc

Part 3 Specifications
3.1 General Characteristics
The 56F803 is fabricated in high-density CMOS with 5-V tolerant TTL-compatible digital inputs. The term
“5-V tolerant” refers to the capability of an I/O pin, built on a 3.3V-compatible process technology, to
withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices
designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V and 5V-compatible
I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V
normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings
of 3.3V I/O levels while being able to receive 5V levels without being damaged.
Absolute maximum ratings given in
maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent
damage to the device.
The 56F803 DC/AC electrical specifications are preliminary and are from design simulations. These
specifications may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized
specifications will be published after complete characterization and device qualifications have been
completed.

This device contains protective circuitry to guard against damage due
to high static voltage or electrical fields. However, normal precautions
are advised to avoid application of any voltages higher than maximum
rated voltages to this high-impedance circuit. Reliability of operation is
enhanced if unused inputs are tied to an appropriate voltage level.
