6521

The 6521 is a 10-channel multiplexer low current Scanner Card designed for switching low currents in multipoint testing applications or when the test configuration must be changed. Offset current on each channel is <lt/>1pA and high isolation is maintained between each channel (10¹⁵Ω). The device maintains the current path even when the channel is deselected, making it a true current switch. BNC input connectors help provide shielding for sensitive measurements and make the card compatible with low noise coaxial cables. The device is well suited for automating reverse leakage tests on semiconductor junctions or gate leakage tests on FETs. It offers contact configurations of single-pole, break-before-make for signal HI input. Signal LO is common for all 10 channels and output. When a channel is OFF, signal HI is connected to signal LO.
