CBT3244ABQ,115

Signal Switches, Multiplexers, Decoders Overview

The CBT3244ABQ,115 is an octal bus switch with quad output enables manufactured by Nexperia USA Inc. It provides eight bits of high-speed TTL-compatible bus switching in a standard '244 device pinout. The device is organized as two 4-bit low-impedance switches with separate output-enable (OE) inputs. It operates from a supply voltage range of 4.5 V to 5.5 V and is characterized for operation from -40 °C to +85 °C. The DHVQFN20 package measures 2.5 x 4.5 x 0.85 mm.
