| PI5A101 Precision Wide-Bandwidth Analog Switch Features * * * * * * * * * * * Rail-To-Rail operation Pin-compatible with 3125 Bus Switch & 74 series 125 Single-Supply operation: 2V to 6V Low On-Resistance: 8 typical @ 5V Tight match between channels: 0.9 typical RON flatness: 3 typical Low power consumption: 0.5-ohm typical High Speed, TON = 8ns typical High-current channel capability: >100mA Wide bandwidth: >200 MHz Packaging (Pb-free & Green available): -14-pin SOIC (W) -16-pin QSOP (Q) Description Pericom Semiconducto's PI5A101 is an all-purpose analog switch designed for single-supply operation from +2V to +6V. This switch is ideal for audio, video, and data switching and routing. The PI5A101 is a quad SPST (single-pole, single-throw) NC (normally closed) function. When on, each switch conducts current equally well in either direction. When off, they block voltages up to the powersupply rails. The PI5A101 is fully specified with +5V and +3.3V supplies. With +5V the RON is 8 typical, making it ideal for replacing mechanical relays in data communications, test equipment, and instrumentation applications. Matching between channels is better than 2. RON flatness is better than 4 over the specified range. These analog switches also offer wide bandwidth (>200 MHz high speed (TON >15ns), and low charge injection (Q >10pC). The PI5A101 is available in the narrow-body 14-pin small SOIC and 16-pin QSOP packages for operation over the industrial (-40C to +85C) temperature range.
