Notes
1. Signals on NC, COM, or IN exceeding VCC or GND are clamped by internal diodes. Limit forward diode current to 0mA.
2. Caution: Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions beyond those ndicated in the operational sections of this specification is not implied.
DescriptionPericom 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 power-supply 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 (40°C to +85°C) temperature range.
