DG4599 Vishay Siliconix
Low-Voltage Single-Supply, SPDT Analog Switch in SC-70
DESCRIPTION
FEATURES
The DG4599 is a cost effective upgrade to other types of 4599 low-voltage, single-pole/double-throw analog switches available in the industry today.
• • • •
Combining low power, high speed, low on-resistant and small physical size, the DG4599 is ideal for portable and battery powered applications. The DG4599 is built on Vishay Siliconix’s low voltage CMOS process. An epitaxial layer prevents latchup. Break-before make is guaranteed for DG4599. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
6-Pin SC-70 Package 60 Ω Max. (26 Typ.) On-Resistance 2 Ω Typ. RON Flatness Fast Switching: tON = 30 ns (Max.) tOFF = 25 ns (Max.) • 2.25 V to 5.5 V Single Supply Operation • Break-Before-Make Switching • TTL/CMOS-Logic Compatible
Pb-free Available

Notes: a. Room = 25 °C, Full = as determined by the operating suffix. b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. c. Typical values are for design aid only, not guaranteed nor subject to production testing. d. Guarantee by design, nor subjected to production test. e. VIN = input voltage to perform proper function. f. Guaranteed by 5 V leakage testing, not production tested. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
