10.1 General Characteristics

The 56F8322/56F8122 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 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 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 56F8122 device is guaranteed to 40MHz 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  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.
