a. Output Driver/Input Address Correspondence
b. Setting Address with LEDs
c. Setting Address without LEDs
If an LED is to be connected on an LED output, an LED and resistor are
tied to V

If no LEDs are needed on the LED outputs, the selection of addresses
can be done as shown in
pin should be tied to V
and latches in a HIGH address value. If a LOW address is desired, the
LED output pins should be tied through a 50 K
