10.1 General Characteristics
The 56F8347/56F8147 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.

maximum-rated voltages to this high-impedance circuit.
Reliability of operation is enhanced if unused inputs are
tied to an appropriate voltage level.
