SN74ALS29827DWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29827DWG4 is a 10-bit buffer and bus driver with 3-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 features PNP inputs that reduce DC loading and provides data flow-through pinout configuration. Propagation delay ranges from 7 ns to 15 ns depending on load capacitance, while output drive capability reaches 48 mA low-level current.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides high-performance bus interface for wide data paths or parity buses
• Features two-output-enable inputs (OE1, OE2) controlling 3-state outputs via NOR logic
• PNP inputs reduce DC loading on driving circuits
• Ensures power-up high-impedance state for safe bus initialization

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in computer systems
• Buffering memory address registers
• Wide data path interfaces
• Parity bus applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS compliance per TI standards. Confirm the DW package corresponds to the plastic small-outline variant. Ensure the ordering part number matches the specific logic function required, as the base model family includes both true and inverted output variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 10-bit non-inverting buffer with tri-state control is required for ALS speed performance. The dual enable inputs allow flexible bus arbitration. Verify that the 5V logic levels and 48 mA sink current meet the system's electrical requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74ALS series of advanced low-power Schottky logic. It is functionally equivalent to the AMD AM29827. The SN74ALS29827 provides true data outputs, whereas the SN74ALS29828 provides inverted data. Both share identical pinouts and electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Functionally equivalent parts include the AMD AM29827. Direct replacements must maintain the 10-bit width, 3-state outputs, and ALS logic family specifications.
