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 Pericoms 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.
