Pin No. Mnemonic Description
1 V
DD
Most Positive Power Supply Potential.
2 NC No Connect.
3
RS
Reset. The RS signal clears both the address and enable data in the latches resulting in no output (all switches off).
4 S16 Source Terminal. This pin can be an input or output.
5 S15 Source Terminal. This pin can be an input or output.
6 S14 Source Terminal. This pin can be an input or output.
7 S13 Source Terminal. This pin can be an input or output.
8 S12 Source Terminal. This pin can be an input or output.
9 S11 Source Terminal. This pin can be an input or output.
10 S10 Source Terminal. This pin can be an input or output.
11 S9 Source Terminal. This pin can be an input or output.
12 GND Ground (0 V) Reference.
13
WR
Write. The WR signal latches the state of the address control lines and the enable line.
14 A3 Logic Control Inputs. Selects which source terminal is connected to the drain (D).
15 A2 Logic Control Inputs. Selects which source terminal is connected to the drain (D).
16 A1 Logic Control Inputs. Selects which source terminal is connected to the drain (D).
17 A0 Logic control inputs. Selects which source terminal is connected to the drain (D).
18 EN Enable. Active high logic control input.
19 S1 Source Terminal. This pin can be an input or output.
20 S2 Source Terminal. This pin can be an input or output.
21 S3 Source Terminal. This pin can be an input or output.
22 S4 Source Terminal. This pin can be an input or output.
23 S5 Source Terminal. This pin can be an input or output.
24 S6 Source Terminal. This pin can be an input or output.
25 S7 Source Terminal. This pin can be an input or output.
26 S8 Source Terminal. This pin can be an input or output.
27 V
SS
Most Negative Power Supply Potential.
28 D Drain Terminal. This pin can be an input or output.
