Description
The PS381/PS383/PS385 are improved high precision, medium voltage analog switches designed to operate with +3V to +8V power supplies. The PS381 has two normally open (NO) switches. The PS383 is a dual, single-pole double-throw (SPDT) switch. The PS385 is a dual, double-pole single-throw (DPST) function. Each switch conducts current equally well in either direction when on. In the off state each switch blocks voltages up to the power-supply rails. With ±5V power supplies, the PS381/PS383/PS385 guarantee <30 on-resistance. On-resistance matching between channels is within 2. On-resistance flatness is less than 4 over the specified range. All three devices feature low leakage currents (<2 pA @ 25oC, <2.5nA @ +85oC) and fast switching speeds (tON < 130ns). Break-before-make switching action protects against momentary crosstalk (PS383). These switches are fully specified for single +5V operation, with <45 RON, <2 RON match, and <4 RON flatness. For operation below 5V the PI5A381A/PI5A383A/PI5A385A are also recommended.

Notes: 1. The algebraic convention, where the most negative value is a minimum and the most positive is a maximum, is used in this data sheet. 2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing. 3. Guaranteed by design 4. R = R max - R min 5. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured. 6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC. 7. Off Isolation = 20log10 [ VCOM / (VNO or VNO) ]. See figure 5. 8. Between any two switches. See figure 6.
