Table 5. ADG527A Pin Function Descriptions
Pin No. Mnemonic Description
1 V
DD
Most Positive Power Supply Potential.
2 DB Drain Terminal. This pin can be an input or output.
3
RS
Reset. The RS signal clears both the address and enable data in the latches resulting in no output (all switches off).
4 S8B Source Terminal. This pin can be an input or output.
5 S7B Source Terminal. This pin can be an input or output.
6 S6B Source Terminal. This pin can be an input or output.
7 S5B Source Terminal. This pin can be an input or output.
8 S4B Source Terminal. This pin can be an input or output.
9 S3B Source Terminal. This pin can be an input or output.
10 S2B Source Terminal. This pin can be an input or output.
11 S1B 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 NC No Connect.
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 S1A Source Terminal. This pin can be an input or output.
20 S2A Source Terminal. This pin can be an input or output.
21 S3A Source Terminal. This pin can be an input or output.
22 S4A Source Terminal. This pin can be an input or output.
23 S5A Source Terminal. This pin can be an input or output.
24 S6A Source Terminal. This pin can be an input or output.
25 S7A Source Terminal. This pin can be an input or output.
26 S8A Source Terminal. This pin can be an input or output.
27 V
SS
Most Negative Power Supply Potential.
28 DA Drain Terminal. This pin can be an input or output.
