These high-precision device is ideal for lowdistortion audio, video, signal switching and routing. Minimizes Distortion and Error Voltages 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 • On-Resistance Matching Channels, 0.8Ω typ • On-Resistance Flatness, 3Ω 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 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, theyt guarantee <10Ω on-resistance. On-resistance matching between channels is within 2Ω. On-resistance flatness is less than 5Ω 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, and PDIP packages for operation over the industrial (-40oC to +85 oC) temperature range.
