74ABT16244CSSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16244CSSCX is a 16-bit buffer and line driver featuring non-inverting outputs with 3-STATE control. It utilizes Advanced BiCMOS technology for high-speed performance while maintaining low power consumption. The device is nibble-controlled, allowing independent operation of four-bit groups or combined 16-bit functionality. It offers robust output drive capabilities with sink currents up to 64 mA and source currents up to 32 mA. Designed for memory address drivers, clock distribution, and bus-oriented transmitters, it ensures glitch-free bus loading during power cycles.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering code. The CSSC suffix denotes a 48-Lead Small Shrink Outline Package (SSOP). Confirm that the required operating temperature range aligns with the specified -40°C to +85°C ambient limits. Ensure supply voltage requirements match the recommended 4.5V to 5.5V range for proper logic level compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed data transmission requires significant drive strength for long traces or multiple loads. The nibble control feature provides flexibility for systems needing partial bus activation. Consider the SSOP package constraints regarding thermal dissipation and board space. Verify input voltage thresholds meet the system's logic levels for reliable HIGH and LOW recognition.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT logic family, characterized by Advanced BiCMOS technology. It serves as the 16-bit counterpart to the 8-bit ABT244 buffer.
