• ON-Resistance Flatness: 10 Ohms (Max.)
• TTL/CMOS Logic Compatible (with +5V or ±5V supplies)
• Fast Switching Speed, t_TRANS <250ns
• Break-Before-Make action eliminates momentary crosstalk
• Rail-to-Rail Analog Signal Range
• Low Power Consumption, 10µW
• Pin Compatible with MAX396
• SOIC and SSOP Packages Minimize Board Area
Description
The PS396 low-voltage, CMOS analog multiplexer offers low ON-
resistance (100 ohms max.), which is matched to within 6 ohms
between switches and remains flat over the specified signal range
(10 ohms max). The PS396 is a 16-channel device.
The PS396 are fabricated using Pericom’s 17V silicon gate process.
Design improvements yield extremely low charge injection (5pC
max).
This multiplexer operates with a single +2.7V to +16V supply or with
±2.7V to ±8V dual supplies, while retaining CMOS-logic input
compatibility and fast switching. The PS396 is pin compatible with
the MAX396.
