CBT3244APW,112

Signal Switches, Multiplexers, Decoders Overview

The CBT3244APW,112 is an octal bus switch providing eight bits of high-speed TTL-compatible data routing within a standard '244 device pinout. It features two independent 4-bit low-impedance switches with separate active LOW output-enable inputs. The component operates from a 4.5 V to 5.5 V supply and supports bidirectional data flow between ports A and B when enabled. It offers a maximum ON-state resistance of 15 Ω and a propagation delay of 0.25 ns. The device is characterized for ambient temperatures ranging from -40 °C to +85 °C and is housed in a TSSOP20 package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix ',112' against current manufacturer documentation to confirm packaging details and availability status. Confirm that the TSSOP20 package variant matches the required footprint for the target PCB design. Check for any recent product change notifications or lifecycle updates regarding this part number before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a standard '244 pinout is required for octal bus switching with TTL logic compatibility. Ensure the application voltage remains within the 4.5 V to 5.5 V range. Consider the thermal environment as the device is rated for operation up to +85 °C. Verify that the required ESD protection levels meet the system specifications, specifically the 2000 V HBM rating.

Signal Switches, Multiplexers, Decoders Part Context

The CBT3244A series belongs to NXP's family of high-speed bus switches designed for efficient data routing. These devices utilize low ON-state resistance technology to minimize propagation delays while maintaining signal integrity. The series includes various package options such as SO20, SSOP20, and DHVQFN20 to accommodate different board space and thermal requirements.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct replacements include other CBT3244A variants with different package styles, such as CBT3244AD (SO20) or CBT3244ADS (SSOP20), provided the pinout remains identical. Verify functional equivalence and electrical characteristics before substituting.
