These high-precision devices are ideal for low-distortion audio, video, signal switching and routing applications. Minimizes Distortion and Error Voltages • RON Matching Between Channels, 0.4 Ω typ • On-Resistance Flatness, 2Ω typ • Low Charge Injection. Q=4pC typ. The PI5A391A is a quad single-pole single-throw (SPST), normally closed (NC) switch. The PI5A392A has four normally open (NO) switches. The PI5A393A has two NC and two NO switches per package. Reduces Step errors, clicking, popping noise • High Speed. tON, 10ns typ • Very Low Crosstalk: -72dB @ 30 MHz • Wide -3dB Bandwidth: >200 MHz • High-Current Channel Capability: >100mA • TTL/CMOS Logic Compatible • Low Power Consumption (0.5µW typ) • Pin-compatible with DG3XX, DG4XX, MAX39X Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails. The PI5A391A/392A/393A are fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <12Ω on-resistance. On-resistance matching between channels is within 2Ω. On-resistance flatness is less than 4Ω over the full signal range. The PI5A39X family guarantees fast switching speeds (t ON < 20ns). Applications • Audio, Video Switching and Routing • Battery-Powered Communication Systems • Computer Peripherals • Telecommunications • Portable Instrumentation • Mechanical Relay Replacement These products are available in the 16-pin narrow-body SOIC, QSOP, and PDIP packages for operation over the industrial (-40oC to +85 oC) temperature range.
