The RLCS4899 is a quad SPDT analog switch featuring ultra-low 0.5Ω on-resistance (typical at 3.0V
VCC), operating from 2.3V to 4.5V with break-before-make switching. Its TTL-compatible control
inputs integrate smart circuitry to minimize VCC leakage when control voltages are below VCC,
enabling direct baseband processor GPIO interfacing without level shifters for optimal power
efficiency in mobile applications. The RLCS4899 is available in QFN1.8x2.6-16L package.
