ISL84541CP Description

The ISL84541CP is a high-performance, single-pole single-throw normally open (SPST-NO) switch designed by Intersil, a renowned manufacturer in the electronics industry. This switch is housed in an 8-DIP package and is ideal for a variety of applications requiring reliable and efficient signal routing. The ISL84541CP operates within a temperature range of 0°C to 70°C, making it suitable for use in standard environmental conditions. It features a maximum leakage current of 100 pA, ensuring minimal power loss when the switch is off.

The ISL84541CP supports a wide supply voltage range of 2.7V to 12V, providing flexibility for different power supply configurations. Its on-state resistance is a maximum of 60 ohms, which is relatively low compared to similar models, resulting in minimal voltage drop and power dissipation when the switch is on. The channel-to-channel matching of 800 mOhm ensures consistent performance across multiple channels, while the channel capacitance of 8pF for both CS(off) and CD(off) states contributes to fast switching times and minimal signal distortion.

The switch time for the ISL84541CP is impressively fast, with a maximum turn-on time (Ton) of 100ns and a turn-off time (Toff) of 75ns. This rapid switching capability is crucial for applications requiring high-speed signal switching. The charge injection is limited to 1pC, which helps in maintaining signal integrity and reducing noise.
