Pin Description Pin #* Name Description 1Y3 Y3 Analog (Input/Output): this is connected to the Y3 column of the switch array. 2AY2 Y2 Address Line (Input). 3RESET Master RESET (Input): this is used to turn off all switches. Active High. 4,5 AX3,AX0 X3 and X0 Address Lines (Inputs). 6,7 NC No Connection. 8-13 X6-X11 X6-X11 Analog (Inputs/Outputs): these are connected to the X6-X11 rows of the switch array. 14 NC No Connection. 15 Y7 Y7 Analog (Input/Output): this is connected to the Y7 column of the switch array. 16 NC No Connection. 17 Y6 Y6 Analog (Input/Output): this is connected to the Y6 column of the switch array. 18 STROBE STROBE (Input): enables function selected by address and data. Address must be stable before STROBE goes high and DATA must be stable on the falling edge of the STROBE. Active High. 19 Y5 Y5 Analog (Input/Output): this is connected to the Y5 column of the switch array. 20 VSS Ground Reference. 21 Y4 Y4 Analog (Input/Output): this is connected to the Y4 column of the switch array. 22, 23 AX1,AX2 X1 and X2 Address Lines (Inputs). 24, 25 AY0,AY1 Y0 and Y1 Address Lines (Inputs). 26, 27 NC No Connection. 28 - 33 X5-X0 X5-X0 Analog (Inputs/Outputs): these are connected to the X5-X0 rows of the switch array. 34 NC No Connection. 35 Y0 Y0 Analog (Input/Output): this is connected to the Y0 column of the switch array. 36 NC No Connection. 37 Y1 Y1 Analog (Input/Output): this is connected to the Y1 column of the switch array. 38 DATA DATA (Input): a logic high input will turn on the selected switch and a logic low will turn off the selected switch. Active High. 39 Y2 Y2 Analog (Input/Output): this is connected to the Y2 column of the switch array. 40 VDD Positive Power Supply. 40 PIN CERDIP/PLASTIC DIP 44 PIN PLCC 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 AY2 RESET AX3 AX0 NC NC X6 X7 X8 X9 X10 X11 NC Y7 NC Y6 STROBE Y5 VSS Y3 Y2 DATA Y1 NC Y0 NC X0 X1 X2 X3 X4 X5 NC NC AY1 AY0 AX2 AX1 Y4 VDD NC NC X6 X7 X8 X9 X10 X11 NC NC NC 1 65432 44 43 42 41 40 7 8 9 10 11 12 13 14 15 16 39 38 37 36 35 34 33 32 31 30 23 18 19 20 21 22 24 25 26 27 28 17 29 NC NC X0 X1 X2 X3 X4 X5 NC NC NC |
