Description

Pericom 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 power­supply rails.

The PI5A101 is fully specified with +5V and +3.3V supplies. With
+5V the R
mechanical relays in data communications, test equipment, and
instrumentation applications. Matching between channels is
better than 2 ohms. RON flatness is better than 4 ohms over the
specified range.

These analog switches also offer wide bandwidths (>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.

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. ∆R

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.
