Preliminary

Part 10 Specifications

10.1 General Characteristics

The 56F8367/56F8167 are fabricated in high-density CMOS with 5V-tolerant TTL-compatible digital

inputs. The term “5V-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 sytems, 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 combined with the ability to receive 5V levels without damage.

Absolute maximum ratings in Table 10-1 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.

Note: All specifications meet both Automotive and Industrial requirements unless individual

specifications are listed.

Note: The 56F8167 device is guaranteed to 40HMz and specified to meet Industrial requirements only.

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

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.
