74CBTLV3244BQ,115

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74CBTLV3244BQ,115 is an 8-bit bus switch with dual 4-pole single-throw channels and independent output enables. It operates on a supply voltage range of 2.3 V to 3.6 V. The device features Schmitt trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. It utilizes a DHVQFN20 package (SOT764-1) with dimensions of 2.5 x 4.5 x 0.85 mm. Propagation delay ranges from 0.13 ns to 0.31 ns depending on voltage. ON resistance varies between 4.0 Ω and 15.0 Ω based on current and temperature.
