ISL84581IAZ - Renesas Electronics

Description: The Intersil ISL84581 device contains precision, bidirectional, analog switches configured as an 8-to-1 multiplexer/demultiplexer. It was designed to operate from a single +2V to +12V single supply or from dual ±2V to ±6V supplies. The device has an inhibit pin to simultaneously open all signal paths. The ISL84581 has an ON-resistance of 39Ω with a dual ±5V supply and 125Ω with a single +3. 3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0. 02nA at +25°C or 0.

ISL84581IAZ Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the ISL84581IAZ. Renesas recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital sections separate. Additionally, use short traces and avoid vias under the IC. Refer to the Renesas application note AN1443 for more details.
  • The ISL84581IAZ has built-in ESD protection, but it's still important to follow proper ESD handling procedures during assembly and testing. Use an ESD wrist strap or mat, and ensure that the PCB is properly grounded. For additional protection, consider adding external ESD diodes or TVS devices.
  • To ensure proper operation, power up the VCC pin first, followed by the VDD pin. The power-up sequence should be VCC > VDD > EN. This sequence helps prevent latch-up and ensures that the internal voltage regulators are properly initialized.
  • To minimize power consumption, use the lowest possible supply voltage (VCC and VDD), and adjust the EN pin to control the device's operating mode. Additionally, consider using the device's built-in shutdown mode (EN = 0) when not in use. Refer to the datasheet for more information on power-saving modes.
  • The ISL84581IAZ is rated for operation from -40°C to +125°C (junction temperature). However, the device's performance may degrade at extreme temperatures. Ensure that the device is properly heat-sinked and that the operating temperature is within the recommended range for optimal performance.
