NL5S4599DFT2G

The NL5S4599DFT2G is a single-pole double-throw analog switch in the miniature SC-88 package, supplied on tape and reel for space-constrained signal routing in portable and industrial equipment. It runs from a single 2.0 V to 5.5 V supply and keeps on-resistance low and flat: 25 Ω maximum at 5.5 V with only 6 Ω of flatness at 4.5 V, so audio and sensor signals pass with minimal level error. A 200 MHz bandwidth, -93 dB off-isolation at 100 kHz, 3 pC charge injection and a typical 8 ns turn-on time preserve signal integrity during fast channel changes, while guaranteed break-before-make action prevents momentary shorts between sources. The select input tolerates 5.5 V regardless of the supply rail and uses CMOS thresholds referenced to VCC, and ESD protection exceeds 4 kV HBM; operation spans -55 °C to +125 °C. Selection note: pick the S version when your select logic swings with the same rail that powers the switch; the NL5ST4599D sibling uses fixed TTL thresholds instead and suits 5 V logic driving a lower-voltage rail.
