DG2737, DG2738, DG2739 Vishay Siliconix 6-Ω, Low Voltage, Dual SPST Analog Switch DESCRIPTION FEATURES The DG2737, DG2738 and DG2739 are high performance, low on-resistance analog switches of dual SPST configuration. • • • • • • • Built on Vishay Siliconix's sub-micro CMOS technology, the DG2737, DG2738, DG2739 achieve switch on-resistance of 6 Ω at 3 V V+. Its - 3 dB bandwidth is typically 720 MHz. It can switch signals with amplitudes of up to VCC to be transmitted in either direction. Voltage range: 2.3 V to 4.3 V Low on-resistance: 6 Ω typ. at 3 V - 48 dB crosstalk at 240 MHz RoHS COMPLIANT Low power consumption Ultra small miniQFN8 package of 1.4 x 1.4 x 0.55 mm > 300 mA latch up current per JESD78 Switch exceeds 5 kV ESD/HBM Combining low power, high speed, low on-resistance and small physical size, the DG2737, DG2738, DG2739 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2737, DG2738, DG2739 come in a small miniQFN-8 lead package (1.4 x 1.4 x 0.55 mm). As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations and is 100 % RoHS compliant.
