ADG741/ADG742 are CMOS low voltage 2Ω SPST switches with a single supply range of 1.8V to 5.5V. The switch on resistance is only 2Ω and the switching time is tON 18ns tOFF 12ns. The working frequency can reach 200MHz.
The ADG741 and ADG742 are monolithic CMOS SPST switches designed for low power dissipation, high switching speed, low on‑resistance and low leakage. They operate from a single 1.8 V to 5.5 V supply, making them suitable for battery‑powered, communication, audio, video and sample‑and‑hold applications.
The devices are offered in 5‑lead and 6‑lead SC70 packages and feature typical on‑resistance of 2 Ω (5 V) or 3.5 Ω (3 V), leakage currents in the sub‑nanampere range, switching times of about 12 ns (on) and 8 ns (off), and a –3 dB bandwidth greater than 200 MHz.
| On Resistance (Ron) at 5 V | 2 Ω typ |

| On Resistance (Ron) at 3 V | 3.5 Ω typ |
| Source OFF Leakage Current | 0.01 nA typ |
| Bandwidth (‑3 dB) | >200 MHz |
The devices operate from a single 1.8 V to 5.5 V supply.
Typical on‑resistance is about 2 Ω at a 5 V supply.
The –3 dB bandwidth is greater than 200 MHz.
