ISL5123CBZ Description

The ISL5123CBZ is a single-pole double-throw (SPDT) analog switch designed by Intersil, a leading manufacturer in the electronics industry. This device is housed in an 8SOIC package and is known for its robust performance and reliability. The ISL5123CBZ features an on-state resistance (R_on) of a maximum of 20 ohms, ensuring minimal signal attenuation and high efficiency in signal routing. It operates within a wide supply voltage range of 2.7V to 12V, making it versatile for various power supply configurations.

The ISL5123CBZ also boasts a low leakage current of 100 picoamperes (pA) maximum, which is crucial for maintaining signal integrity and reducing power consumption in low-power applications. Its channel-to-channel matching (ΔR_on) is 800 milliohms, ensuring consistent performance across multiple channels. The channel capacitance (C_S(off), C_D(off)) is rated at 8 pF for both source and drain, which helps in maintaining signal fidelity at high frequencies.

The switch time (T_on, T_off) is exceptionally fast, with a maximum of 35 ns for turn-on and 30 ns for turn-off, making it suitable for high-speed signal switching applications. The charge injection is limited to 5 picoCoulombs (pC), which minimizes signal distortion during switching events. The ISL5123CBZ is also compliant with ROHS3 standards, ensuring environmental sustainability and regulatory compliance.
