SN74ALS29827DWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29827DWRE4 is a 10-bit buffer and bus driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature from 0°C to 70°C. The device provides high-level output currents up to -24 mA and low-level output currents up to 48 mA. Propagation delays are specified at 15 ns maximum for a 300 pF load and 8 ns maximum for a 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features PNP inputs that reduce DC loading on driving circuits
• Includes power-up high-impedance state for safe initialization
• Utilizes data flow-through pinout with all inputs positioned opposite the outputs

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in wide data path architectures
• Buffering memory address registers
• Handling buses carrying parity information

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the RE4 suffix indicates lead-free composition and RoHS compliance per the manufacturer's package addendum. Confirm the SOIC-24 package dimensions match the target PCB footprint. Ensure the 0°C to 70°C commercial temperature rating aligns with the system environment requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing wide data paths requiring ten parallel channels. The ALS logic family offers faster switching speeds compared to standard TTL. Verify that the 4.75 V to 5.25 V supply voltage matches the system power rails. Consider the specific input/output current capabilities if driving heavy capacitive loads.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALS29827/29828 series of 10-bit buffers and bus drivers. It is functionally equivalent to the AMD AM29827. The device is designed for high-performance bus interfaces and is characterized for operation across the commercial temperature range.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ALS29827DW is a direct functional substitute. The SN74BCT29827BDW is a similar 10-bit buffer but utilizes BCT logic technology rather than ALS.
