74F244SJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F244SJX is an octal buffer and line driver featuring three-state outputs, designed for memory and address drivers, clock drivers, and bus-oriented transmitters. It operates within a supply voltage range of +4.5V to +5.5V. The device provides a source current of 12 mA and sinks up to 64 mA. Propagation delay ranges from 3.0 ns to 8.0 ns at VCC = 5.0V with CL = 50 pF. It utilizes a 20-lead Small Outline Package (SOP) conforming to EIAJ TYPE II standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm that the SOP package dimensions match the EIAJ TYPE II specification. Ensure compatibility with existing PCB footprints and verify RoHS compliance details directly with the supplier documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with high drive capability. The 64 mA sink current supports heavy bus loading. Verify that the operating temperature range meets environmental requirements. Consider the propagation delay specifications for signal integrity in high-speed clock distribution networks.
