Pinout

Pin Name Type Function
1 EA input Enable input for decoder A; per the function table, when EA is HIGH all outputs O0A-O3A are HIGH regardless of the address inputs.
2 A0A input Address input (A0) for decoder A, selecting which of outputs O0A-O3A goes LOW when EA is LOW.
3 A1A input Address input (A1) for decoder A, selecting which of outputs O0A-O3A goes LOW when EA is LOW.
4 O0A output Decoder A output 0, active LOW; it is driven LOW when EA is LOW and A1A/A0A select 0 (A1=L, A0=L).
5 O1A output Decoder A output 1, active LOW; it is driven LOW when EA is LOW and A1A/A0A select 1 (A1=L, A0=H).
6 O2A output Decoder A output 2, active LOW; it is driven LOW when EA is LOW and A1A/A0A select 2 (A1=H, A0=L).
7 O3A output Decoder A output 3, active LOW; it is driven LOW when EA is LOW and A1A/A0A select 3 (A1=H, A0=H).
8 VSS power_in Ground supply voltage; all voltages in the datasheet are referenced to VSS (0 V).
9 O3B output Decoder B output 3, active LOW; it is driven LOW when EB is LOW and A1B/A0B select 3 (A1=H, A0=H).
10 O2B output Decoder B output 2, active LOW; it is driven LOW when EB is LOW and A1B/A0B select 2 (A1=H, A0=L).
11 O1B output Decoder B output 1, active LOW; it is driven LOW when EB is LOW and A1B/A0B select 1 (A1=L, A0=H).
12 O0B output Decoder B output 0, active LOW; it is driven LOW when EB is LOW and A1B/A0B select 0 (A1=L, A0=L).
13 A1B input Address input (A1) for decoder B, selecting which of outputs O0B-O3B goes LOW when EB is LOW.
14 A0B input Address input (A0) for decoder B, selecting which of outputs O0B-O3B goes LOW when EB is LOW.
15 EB input Enable input for decoder B; per the function table, when EB is HIGH all outputs O0B-O3B are HIGH regardless of the address inputs.
16 VDD power_in Supply voltage; recommended operating range is 3 V to 15 V, with an absolute maximum of 18 V.
