Electrical Characteristics and Timing

CAUTION:

Exceeding maximum electrical ratings will permanently damage or

disable the chip, or impair the chip’s long term reliability.

The DSP56156 is fabricated in high density HCMOS with TTL compatible inputs and CMOS

compatible outputs.

NOTE: 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 logic voltage level (e.g., either GND or VCC).
