Chip Scale Packaging, Dual SPDT Analog Switch
Features
Description
• CMOS Technology for Bus and Analog Applications
Pericom Semiconductor's PI5A4684 is a dual high-bandwidth,
fast single-pole double throw (SPDT) CMOS switch. It can be
used as an analog switch or as a low-delay bus switch. Specified
over a wide operating power supply voltage, 1.65V to 5.5V, the
PI5A4684 has a maximum On-Resistance of 0.5Ω at +2.7V.
• Low On-Resistance: 0.5Ω.
• Wide V Range: 1.65V to 5.5V
CC
• Rail-to-Rail Signal Range
• Control Input Overvoltage Tolerance: 5.5V min.
• High Off Isolation: -42dB
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
• Crosstalk Rejection Reduces Signal Distortion: -70dB
• Low THD (0.05% @ V = 2.7V)
CC
The control input, IN , tolerates input drive signals up to 6.0V,
X
• Break-Before-Make Switching
independent of supply voltage.
• Extended Industrial Temperature Range: –40°C to 85°C
• Packaging (Pb-free & Green):
– 10-ball Chip Scale Packaging (CSP)

Notes:
1. "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.
2. The input and output negative voltage ratings may be exceeded if the inut and output diode current ratings are observed.
3. Control input must be held HIGH or LOW; it must not float.
