Input Definitions In this table, V DD and V SS are considered to be normal operating input logic levels. Actual input low and high levels are specified
under Operating Characteristics. For lowest power consumption, input signals should swing over the full supply.

FUNCTION
DA1 and DA2 serve as a 2-bit Digit Address Input
DA2, DA1 = 00 selects D4
DA2, DA1 = 01 selects D3
DA2, DA1 = 10 selects D2
DA2, DA1 = 11 selects D1
When both CS1 and CS2 are taken low, the data at the Data and Digit
