SN54F244J

Buffers, Drivers, Receivers, Transceivers Overview

The SN54F244J is an octal buffer and line driver featuring three-state outputs, designed for military temperature operation ranging from -55°C to 125°C. It utilizes a 20-pin ceramic dual in-line package (CDIP). The device operates on a supply voltage between 4.5 V and 5.5 V. Electrical characteristics include a maximum propagation delay of 7 ns at 5 V with a 50 pF load. Output drive capabilities provide up to 64 mA low-level current and -15 mA high-level current.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal buffering architecture organized as two independent four-bit sections
• Three-state outputs enable direct connection to bus lines without external drivers
• Symmetrical active-low output-enable inputs control data flow direction
• Military-grade qualification ensures reliability across extreme environmental conditions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and military certification level. Confirm RoHS exemption status if applicable to your assembly process. Ensure the supplier provides traceability documentation consistent with QML or military procurement standards. Check for any recent lifecycle status updates regarding production availability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed signal buffering under harsh thermal conditions. The F-series technology offers faster switching speeds compared to standard LS or S families. Verify that the system power supply remains within the specified 4.5 V to 5.5 V range to maintain timing specifications and output voltage levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN54F24x family of octal buffers and line drivers. It shares functional compatibility with the SN74F244 but differs in operating temperature range and packaging options. The SN54 variant is specifically characterized for full military temperature ranges, distinguishing it from commercial grade equivalents.
