PI5A101 Precision Wide-Bandwidth Analog Switch Features 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. Rail-To-Rail operation Pin-compatible with 3125 Bus Switch & 74 series 125 Single-Supply operation: 2V to 6V Low On-Resistance: 8Ω typical @ 5V Tight match between channels: 0.9Ω typical RON flatness: 3Ω typical Low power consumption: 0.5µ-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) 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 8Ω typical, making it ideal for replacing mechanical relays in data communications, test equipment, and instrumentation applications. Matching between channels is better than 2Ω. RON flatness is better than 4Ω over the specified range. These analog switches also offer wide bandwidth (>200 MHz high speed (TON >15ns), and low charge injection (Q >10pC). Applications • • • • • • Instrumentation, ATE Audio Switching and Routing Telecommunications Systems Data Communications Battery-Powered Systems Replaces Mechanical Relays The PI5A101 is available in the narrow-body 14-pin small SOIC and 16-pin QSOP packages for operation over the industrial (–40°C to +85°C) temperature range.
