General Characteristics
Part 4 Specifications
4.1 General Characteristics
The DSP56852 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 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 DSP56852 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.
