Description

VCC Supply voltage VSS Circuit ground VSS1 Secondary ground (in PLCC only) Provided to reduce ground bounce and improve power supply by-passing NOTE This pin is NOT a substitute for VSS pin (pin 22) Port 0 Port 0 is an 8-bit open drain bidirectional I O port As an output port each pin can sink several LS TTL inputs Port 0 pins that have 1’s written to them float and in that state can be used as high-impedance inputs 270961 2 Example AN87C51FA FB FC indicates an automotive temperatur
