Part 4 Specifications

4.1 General Characteristics

The 56852 is fabricated in high-density CMOS with 5-volt tolerant TTL-compatible digital inputs. The

term “5-volt 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 ±10% during 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 Table 4-1 are stress ratings only, and functional operation at the

maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent

damage to the device.

The 56852 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.

CAUTION

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.
