Key Differentiators

  • Low ON-state resistance of 10 Ω (vs TS5V330PW)
  • Wide supply voltage range of 1.8 V to 3.6 V (vs MAX4535)
  • Fast switching times (5 ns turn-on, 3.5 ns turn-off) (vs ADG884)

Design Notes

Place decoupling capacitors (0.1 µF and 10 µF) close to the V+ pin to ensure stable operation. Use a solid ground plane to minimize noise and improve signal integrity. Keep signal traces short and direct to reduce parasitic capacitance and inductance.

The ON-state resistance of 10 Ω can cause signal attenuation in high-impedance circuits. To minimize this, use low-impedance loads and keep the signal path as short as possible. Additionally, consider the bandwidth limitations of the switch for high-frequency signals.

Ensure the supply voltage does not exceed 3.6 V to avoid damage. The enable pin is active low, so tie it to GND for normal operation. Do not apply signals exceeding V+ to the switch inputs, as this can cause latch-up or damage.
