PI5A121/PI5A122/PI5A124
Wide Bandwidth Analog Switches
Features
Description
• Single-Supply Operation (+2V to +6V)
• Rail-to-Rail Analog Signal Dynamic Range
• Low On-Resistance (6Ω typ. with 5V supply)
Minimizes Distortion and Error Voltages
The PI5A121/PI5A122/PI5A124 are analog switches designed
for single-supply operation. These high-precision devices are
ideal for low-distortion audio, video, signal switching and rout-
ing.
• On-Resistance Flatness, 3Ω typ.
• Low Charge Injection Reduces Glitch Errors. Q = 4pC typ.
The PI5A121 is a single-pole throw (SPST) normally open (NO)
switch. The switch is open when IN is LOW. The PI5A122 is
a single-pole single-throw (SPST) normally closed (NC)
switch.
• High Speed. t = 10ns typ.
ON
• Wide -3dB Bandwidth: 326 MHz (typ.)
• High-Current Channel Capability: >100mA
• TTL/CMOS Logic Compatible
Each switch conducts current equally well in either direction
when on. When off, they block voltages up to V+.
• Low Power Consumption (0.5µW typ)
• Small outline transistor package minimizes board area
• Packaging (Pb-free & Green available):
- 5-pin 65-mil wide SOT23 (T) for PI5A121 and PI5A122
- 6-pin 65-mil wide SOT23 (T) for PI5A124
These switches are fully specified with +5V, and +3.3V supplies.
With +5V, they guarantee <10Ω On-Resistance. On-Resistance
matching between channels is within 2Ω. On-Resistance flatness
is less than 55Ω over the specified range. These switches also
guarantee fast switching speeds (t <20ns).
ON
- 5-pin 50-mil wide SC70 (C) for PI5A121/PI5A122
These products are available in 5-pin SC70 and/or 6-pin SOT23
plastic packages for operation over the industrial (-40 C to +85 C)
temperature range.

Notes:
1. The algebraic convention, where most negative value is a minimum and most positive is a maximum, is used in this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design
4. ∆RON = RON max - RON min
5. Flatness is defined as the difference between the maximum and minimum value of On-Resistance measured.
6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.
7. Off Isolation = 20log10 [ VCOM / (VNO or VNC) ]. See Figure 3.
8. Between any two switches. See Figure 4.
