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 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 2â¦. 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
(â40°C to +85°C) temperature range.
