74CBTLVD3245BQ-Q1X

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74CBTLVD3245BQ-Q1X is an 8-bit level-shifting bus switch with output enable, qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 3.0 V to 3.6 V and supports ambient temperatures from -40 °C to +125 °C. The device features Schmitt trigger control inputs for noise immunity and IOFF circuitry for partial power-down applications. It utilizes a DHVQFN20 package (SOT764-1) with side-wettable flanks. Key electrical parameters include a typical ON resistance of 3.7 Ω at 24 mA, propagation delay of 0.11 ns, enable time of 2.9 ns, and disable time of 3.4 ns.
