GC2011A-PQ

Product Summary

The GC2011A is designed to be a functional and footprint compatible replacement for the GC2011 chip. The timing specifications for the GC2011A meet and exceed the timing specifications for the GC2011. Electrically the GC2011A is a 3.3 volt only part, making it incompatible with the GC2011’s 5 volt mode. The GC2011A is fully compatible with the GC2011’s 3.3 volt mode, but at a lower power consumption. See Section 7 for timing and electrical specifications. NOTE: The GC2011A inputs are NOT 5 volt tolerant; chip damage may occur if the input voltages exceed Vcc + 0.5V (3.8 volts). Designs using the GC2011 at 5 volts will need to add a 3.3 volt supply and voltage level translators to use the GC2011A. The function of the GC2011A has been slightly enhanced, but any enhancements are “backward” compatible with the GC2011 so that a GC2011 user will not need to change any software or processing algorithms to use the GC2011A chip. Highlights of the enhancements follow.
