300 MHz SPST-NO analog switch in a 1.4x0.9 mm DSBGA
The Texas Instruments SN74LVC1G66YZAR is a single-pole single-throw (SPST-NO) analog switch in a 5-bump DSBGA package measuring 1.4x0.9 mm. Switching times are 4.2 ns (ton) and 5 ns (toff), suitable for gating digital clocks or multiplexing fast serial data lines.
DSBGA footprint — layout and assembly constraints
The 5-DSBGA (1.4x0.9 mm) package uses solder bumps on a 0.5 mm pitch. The small footprint requires a fan-out via pattern on the PCB — typically microvias or laser-drilled vias under the component. Hand soldering is not practical; reflow with a stencil is the expected assembly method.
Signal integrity specs for the analog path
Off-state leakage current is 100 nA maximum, and channel capacitance is 6 pF. These low parasitics keep signal feedthrough and crosstalk under control at frequencies up to the 300 MHz -3dB bandwidth.
