DG429DJ-E3 Description

The DG429DJ-E3 is a high-performance, obsolete integrated circuit (IC) switch from Vishay Siliconix, designed for demanding electronic applications. This device features a 4:1 multiplexer/demultiplexer circuit and a SP4T (Single Pole, Four Throw) switch circuit, making it ideal for signal routing and switching tasks. The DG429DJ-E3 is housed in a robust through-hole package, specifically a tube, ensuring reliable mechanical and electrical performance.

Key specifications include a maximum on-state resistance (Ron) of 100 ohms, ensuring minimal signal attenuation and power loss. The device operates with a dual supply voltage of ±15V and a single supply voltage of 12V, providing flexibility in power supply options. The channel-to-channel matching (ΔRon) is tightly controlled at 5 ohms, ensuring consistent performance across multiple channels. Additionally, the DG429DJ-E3 boasts low leakage current (IS(off)) of 500pA and low charge injection of 1pC, which are critical for maintaining signal integrity.

The switch time (Ton, Toff) is maximized at 150ns, offering fast switching capabilities without compromising signal quality. The channel capacitance (CS(off), CD(off)) is rated at 11pF and 20pF respectively, ensuring minimal capacitive loading on the signal lines. The DG429DJ-E3 is also RoHS3 compliant, meeting stringent environmental and safety standards, and has a moisture sensitivity level (MSL) of 1 (unlimited), making it suitable for various environmental conditions.
