74AC16244SSC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC16244SSC is a 16-bit non-inverting buffer and line driver featuring 3-STATE outputs, housed in a 48-Lead Small Shrink Outline Package (SSOP). It operates within a supply voltage range of 2.0V to 6.0V for AC variants. The device provides separate control logic for each byte and nibble, allowing independent or combined operation. Outputs are capable of sourcing and sinking 24 mA. Propagation delays typically range from 4.3 ns to 7.0 ns at 5.0V with 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains sixteen non-inverting buffers with 3-STATE outputs designed for memory, address, clock, or bus applications.
• Features nibble-controlled architecture where each nibble has separate 3-STATE control inputs that can be shorted for full 16-bit operation.
• Outputs provide high drive capability by sourcing and sinking 24 mA.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory and address drivers
• Clock drivers
• Bus oriented transmitter/receiver

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SSC' corresponds to the 48-Lead SSOP package when ordering. Confirm whether the AC or ACT variant is required based on input voltage compatibility needs. Check for tape and reel availability if indicated by an 'X' suffix in ordering codes. Ensure operating temperature ranges meet system requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for systems requiring 16-bit data buffering with independent nibble control. Choose the AC version for wider voltage flexibility (2.0V–6.0V) or the ACT version for TTL-compatible inputs at 5.0V. Consider the SSOP package for space-constrained PCB layouts. Evaluate propagation delay specifications against system timing constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC/ACT16244 family of 16-bit buffer/line drivers. It serves as a 16-bit version of the AC244/ACT244 devices. The family includes variants in SSOP and TSSOP packages. The device is manufactured under Fairchild Semiconductor technology, now associated with onsemi.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include 74ACT16244MTD for the same function in a TSSOP package. Cross-reference pinouts and electrical characteristics before substitution.
