SN74BCT2244DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT2244DWR is an octal buffer and line/MOS driver manufactured by Texas Instruments. It features BiCMOS technology, a 4.5 V to 5.5 V supply voltage range, and SOIC-20 packaging. The device provides non-inverting outputs with 3-state capability and includes internal 33-Ω series resistors. Key electrical parameters include ±12 mA output drive current, 6 pF input capacitance, and propagation delays ranging from 0.5 ns to 7.1 ns at 5 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 33-ohm series resistors in the output path eliminate the need for external components to reduce signal overshoot and undershoot.
• BiCMOS design architecture significantly reduces quiescent current consumption compared to standard bipolar logic families.
• Symmetrical active-low output-enable inputs facilitate bus-oriented receiver and transmitter applications.

• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer's package option addendum. Ensure the selected variant matches the required operating temperature range of 0°C to 70°C for commercial applications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high fan-out and improved fan-in capabilities are necessary for system density. The integrated series resistors simplify board layout by removing external damping requirements. Consider the BiCMOS technology benefits for applications requiring lower power dissipation while maintaining robust drive strength for bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT2244 family of octal buffers and line drivers. It is designed to complement other devices in the BCT series, such as the SN74BCT2240 and SN74BCT2241, offering complementary enable configurations. The DWR suffix specifically denotes the surface-mount SOIC package configuration supplied in a tape-and-reel format.
