The PS323 is a dual, single-pole single-throw (SPST), normally open (NO) switch. The PS324 has the same pinout as the PS323 but it has two normally closed (NC) switches. The PS325 has one normally open (NO) and one normally closed (NC) switch per package. Each switch conducts current equally well in either direction when on. In the off state, each switch blocks voltages up to the power-supply rail. With a +5V power supply, PS323/PS324/PS325 guarantee <60-ohm ON-resistance. ON-resistance matching between channels is within 2W. ON-resistance flatness is less than 6W over the specified range. All three devices guarantee low leakage currents (<100 pA @ 25oC, <10nA @ +85oC) and fast switching speeds (tON<150ns). Break-before-make switching action protects against momentary crosstalk (PS325). For single-supply operation below 5V, PI5A317/318/319 are also recommended. 3 2 3 S P c i g o Lh c t i w S 0 1 F F O N O Switches shown for logic “0” input TopView 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 PS323/PS324/PS325 Precision, Single-Supply SPST Analog Switches FunctionalDiagrams,PinConfigurations,andTruthTables TopView TopView 6 7 8 5 1 2 3 4 NC1 COM1 IN2 GND V+ COM2 NC2 IN1 PS324 6 7 8 5 1 2 3 4 NC1 COM1 IN2 GND V+ COM2 NC2 IN1 PS325 6 7 8 5 1 2 3 4 NO1 COM1 IN2 GND V+ COM2 NO2 IN1 PS323 4 2 3 S P c i g o Lh c t i w S 0 1 N O F F O 5 2 3 S P c i g o Lh c t i w S1 h c t i w S2 0 1 F F O N O N O F F O |
