CD4556BE

lingxingic · Signal Switches, Multiplexers, Decoders · DIP-16

CD4556BE from lingxingic, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EA input Enable input for decoder A; per the function table, EA LOW enables the decoder and EA HIGH forces outputs O0A to O3A HIGH.
2 A0A input Address input A0 for decoder A, selecting which of outputs O0A to O3A goes LOW together with A1A.
3 A1A input Address input A1 for decoder A, selecting which of outputs O0A to O3A goes LOW together with A0A.
4 O0A output Active-LOW output 0 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 00.
5 O1A output Active-LOW output 1 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 01.
6 O2A output Active-LOW output 2 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 10.
7 O3A output Active-LOW output 3 of decoder A, driven LOW when EA is LOW and the address A1A/A0A is 11.
8 VSS power_in Ground supply voltage, the 0 V reference for all voltages on the device.
9 O3B output Active-LOW output 3 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 11.
10 O2B output Active-LOW output 2 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 10.
11 O1B output Active-LOW output 1 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 01.
12 O0B output Active-LOW output 0 of decoder B, driven LOW when EB is LOW and the address A1B/A0B is 00.
13 A1B input Address input A1 for decoder B, selecting which of outputs O0B to O3B goes LOW together with A0B.
14 A0B input Address input A0 for decoder B, selecting which of outputs O0B to O3B goes LOW together with A1B.
15 EB input Enable input for decoder B; per the function table, EB LOW enables the decoder and EB HIGH forces outputs O0B to O3B HIGH.
16 VDD power_in Supply voltage, recommended range 3 V to 15 V referenced to VSS (absolute maximum +18 V).
