As shown in Figure 2 temperature, burn-in, and  
package options are identified by a one- or two-letter  
prefix to the part number.

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-im-  
pedance inputs.
