These high-precision device is ideal for lowdistortion audio, video, signal switching and routing. Minimizes Distortion and Error Voltages On-Resistance Matching Channels, 0.8-ohm typ On-Resistance Flatness, 3-ohm typ Low Charge Injection Reduces Glitch Errors. Q = 4pC typ Replaces Mechanical Relays High Speed. tON= 10ns typ Low Off-Isolation: -72dB@1MHz Wide -3dB Bandwidth: 170 MHz High-Current Channel Capability: >100mA TTL/CMOS Logic Compatible Low Power Consumption (0.5µW typ) Pin-compatible with DG41X, MAX31X The PI5A317A is a single-pole single-throw (SPST), normally closed (NC) switch. The PI5A318A has the same pinout but is a single-pole, single-throw (SPST, normally open (NO) function. The PI5A319A is a single-pole, double-throw (SPDT) switch Each switch conducts current equally well in either direction when on. When off, they block voltages up toVCC. The PI5A317A/381A/319A are fully specified with +5V and +3.3V supplies. With +5V, they guarantee <18-ohm On-Resistance. On-Resistance matching between channels is within 2-ohm. On-Resistance flatness is less than 5-ohm over the specified range. This switch family also guarantees fast switching speeds (tON < 20ns). These products are available in a 8-pin narrow body SOIC package for operation over the industrial (-40oC to +85 oC) temperature range.
