PI5A101
Precision Wide-Bandwidth Analog Switch
Features
Description
• Rail-To-Rail operation
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.
• Pin-compatible with 3125 Bus Switch & 74 series 125
• Single-Supply operation: 2V to 6V
The PI5A101 is a quad SPST (single-pole, single-throw)
NC (normally closed) function.
• Low On-Resistance: 8Ω typical @ 5V
• Tight match between channels: 0.9Ω typical
When on, each switch conducts current equally well in either
direction. When off, they block voltages up to the power-
supply rails.
• R flatness: 3Ω typical
ON
• Low power consumption: 0.5µ-ohm typical
• High Speed, T = 8ns typical
ON
The PI5A101 is fully specified with +5V and +3.3V supplies.
• High-current channel capability: >100mA
• Wide bandwidth: >200 MHz
With +5V the R
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. R flatness is better than 4Ω over the specified
ON
range.
These analog switches also offer wide bandwidth (>200 MHz high

• Instrumentation, ATE
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.
