DG441, DG442 are monolithic CMOS analog switches from Texas Instruments, which are drop-in replacements for the popular DG201A and DG202 series devices. They feature lower analog ON resistance and faster switch time.
The DG441 and DG442 are monolithic CMOS analog switches that replace the DG201A/DG202 series. They provide four independent SPST switches, TTL and CMOS compatible inputs, low charge injection, and a voltage reference. The devices operate from single‑ended +5 V to +34 V or symmetrical supplies up to ±22 V, with a maximum differential voltage of 44 V.
Key features include on‑resistance below 850 Ω, turn‑on time of 250 ns, turn‑off time as low as 120 ns (DG441) or 210 ns (DG442), and low power consumption under 1.6 mW. The parts are offered in PDIP, SOIC, and TSSOP packages and are RoHS‑compliant Pb‑free devices.
Yes, they are Pb‑free and meet RoHS requirements.
They are offered in 16‑lead PDIP, SOIC, and TSSOP packages.
