Pinout

Pin Name Type Function
4 D0 input Multiplexer data input D0, selected onto Y when the select inputs address it and STROBE is low.
3 D1 input Multiplexer data input D1, selected onto Y when the select inputs address it and STROBE is low.
2 D2 input Multiplexer data input D2, selected onto Y when the select inputs address it and STROBE is low.
1 D3 input Multiplexer data input D3, selected onto Y when the select inputs address it and STROBE is low.
15 D4 input Multiplexer data input D4, selected onto Y when the select inputs address it and STROBE is low.
14 D5 input Multiplexer data input D5, selected onto Y when the select inputs address it and STROBE is low.
13 D6 input Multiplexer data input D6, selected onto Y when the select inputs address it and STROBE is low.
12 D7 input Multiplexer data input D7, selected onto Y when the select inputs address it and STROBE is low.
5 Y output Multiplexer output Y, which goes low when STROBE is high.
6 W output Complementary multiplexer output W, which is forced high when STROBE is high.
7 STROBE input Strobe input that must be taken low to enable the device; when high, W is forced high and Y goes low.
11 A input Select input A, the least significant address bit used to choose one of the data inputs D0 to D7.
10 B input Select input B, the middle address bit used to choose one of the data inputs D0 to D7.
9 C input Select input C, the most significant address bit used to choose one of the data inputs D0 to D7.
8 GND power_in Ground (0 V) reference pin for the device.
16 VCC power_in Positive supply voltage, with a recommended operating range of 2 V to 6 V per Table 5.
