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 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).
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.
