Rail-To-Rail operation Pin-compatible with 3125 Bus Switch & 74 series 125 Single-Supply operation: to 6V Low ON-resistance: 8-ohms typical @ 5V Tight match between channels: 0.9-ohm typical RON flatness: 3-ohms typical Low power consumption: 0.5-ohm typical High Speed, TON = 8ns typical High-current channel capability: >100mA Wide bandwidth: >200 MHz Instrumentation, ATE Audio Switching and Routing Telecommunications Systems Data Communications Battery-Powered Systems Replaces Mechanical Relays


Pericom is an all-purpose analog switch designed for single-supply operation from to +6V. This switch is ideal for audio, video, and data switching and routing. The 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 ohms typical, making it ideal for replacing mechanical relays in data communications, test equipment, and instrumentation applications. Matching between channels is better than 2 ohms. RON flatness is better than 4 ohms over the specified range. These analog switches also offer wide bandwidths (>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 to +85C) temperature range.
