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.
Rail-To-Rail operation
Pin-compatible with 3125 Bus Switch & 74 series 125
Single-Supply operation: 2V to 6V
Low On-Resistance: 8Ω typical @ 5V
Tight match between channels: 0.9Ω typical
RON flatness: 3Ω typical
Low power consumption: 0.5µ-ohm typical
High Speed, TON = 8ns typical
High-current channel capability: >100mA
Wide bandwidth: >200 MHz
Packaging (Pb-free & Green available):
-14-pin SOIC (W)
-16-pin QSOP (Q)
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 powersupply 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).

Notes
1. Signals on NC, COM, or IN exceeding VCC or GND are clamped by internal diodes. Limit forward diode current to 30mA.
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 indicated in the operational sections of this specification is not
implied.

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. ΔRΟΝ = RΟΝ MAX - RΟΝ ΜΙΝ
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 VB / VA. See Figure 3.
8. Between any two switches. See Figure 4.
9. D = RFLAT(ON)/RL.
