Precision, 16-Channel/Dual 8-Channel,
17V Analog Multiplexers
Features
Description
• Low ON-Resistance (100 Ohms Max.) Minimizes Distortion
and Error Voltages
• Low Glitching Reduces Step Errors and Improves
Settling Times. Charge Injection: 5pC Max.
• Dual-Supply Operation (±2.7V to ±8V)
• Single-Supply Operation (+2.7V to +16V)
• ON-Resistance Matching Between Channels: <6 Ohms
• ON-Resistance Flatness: 10 Ohms (Max.)
• TTL/CMOS Logic Compatible (with +5V or ±5V supplies)
• Fast Switching Speed, tTRANS <250ns
• Break-Before-Make action eliminates momentary crosstalk
• Rail-to-Rail Analog Signal Range
• Low Power Consumption, 10µW
• Pin Compatible with MAX396/397
• Narrow SOIC and SSOP Packages Minimize Board Area
The PS396/PS397 low-voltage, CMOS analog multiplexers offer 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, and the PS397 is
a dual 8-channel device.
The PS396/PS397 are fabricated using Pericom’s 17V silicon gate
process. Design improvements yield extremely low charge injection
(5pC max).
These multiplexers operate 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/PS397 are pin compatible with MAX396/MAX397.

Notes:
2. The algebraic covention, where most negative value is a minimum and most positive value a maximum, is used in this data sheet.
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 as measured over the specified
analog signal ranges. i.e., VNO = 3V to 0V and 0V to –3V.
6. Leakage parameters are guaranteed by desgin.
7. Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation - 20log VCOM/VNO,
VCOM = output, VNO = input to off switch.
8. Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
