Charge Injection, 3pC typ • Single Supply (+3V to +15V) or Split-Supply (+3V to +8V) Operation • Improved Second Sources for MAX381/MAX383/MAX385 • On-Resistance Matching Between Channels, 0.2 Ω typ • On-Resistance Flatness, 1Ω typ • Low Off-Channel Leakage, <2.5nA @ +85oC • TTL/CMOS Logic Compatible • Rail-to-Rail Analog Signal Dynamic Range • Low Power Consumption <1µA 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 <30Ω on-resistance. On-resistance matching between channels is within 2Ω. On-resistance flatness is less than 4Ω 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). Applications • • • • • • Instrumentation, ATE Sample-and-Holds Audio Switching and Routing Telecommunication Systems PBX, PABX Battery-Powered Systems These switches are fully specified for single +5V operation, with <45Ω RON, <2Ω RON match, and <4Ω RON flatness. For operation below 5V the PI5A381A/PI5A383A/PI5A385A are also recommended.
