LS80C52 Product details

Description

VCC Supply voltage VSS Circuit ground VSS1 Secondary ground (not on DIP) Provided to reduce ground bounce and improve power supply by-passing NOTE This pin is not a substitute for the VSS pin (pin 22) (Connection not necessary for proper operation ) 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 Port 0 is also the multiplex
