Part 10 Specifications
10.1 General Characteristics
The 56F8357/56F8157 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
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 56F8157 device is guaranteed to 40MHz and specified to meet Industrial requirements only.

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