74ABT16244CMTD

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16244CMTD is a 16-bit buffer and line driver featuring 3-STATE outputs, housed in a 48-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient temperature range from -40°C to +85°C. The device provides high drive capability with output sink currents up to 64 mA and source currents up to 32 mA. Propagation delays are specified at 3.9 ns maximum under standard conditions, ensuring reliable data transmission for memory, address, and clock applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Nibble-controlled architecture allowing independent operation of four 4-bit sections or combined 16-bit functionality
• High-drive 3-STATE outputs designed for bus-oriented transmitter/receiver applications
• Glitch-free bus loading maintained throughout the entire power-up and power-down cycle
• Guaranteed simultaneous switching noise levels and dynamic threshold performance

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock signal distribution
• Bus-oriented transmitter/receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the ABT16244 series includes SSOP options. Confirm RoHS compliance status and check for obsolescence notices, as this component originates from Fairchild Semiconductor documentation now managed by onsemi. Ensure the ordering code matches the required TSSOP configuration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit non-inverting buffer with high current drive is required. The nibble control feature offers flexibility for mixed-width data buses. Verify that the 3.9 ns propagation delay meets system timing requirements and that the 48-pin TSSOP footprint fits the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT logic family, known for high-speed CMOS technology. It serves as the 16-bit counterpart to the 8-bit ABT244 buffer. Originally manufactured by Fairchild Semiconductor, the product line has been integrated into onsemi's portfolio following corporate acquisitions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT244 is the 8-bit equivalent within the same family. For direct pin-compatible replacements, verify availability of the 74ABT16244CSSC in the SSOP package or consult onsemi for current active equivalents.
