SN74ALS29827DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29827DWR 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. Electrical characteristics include a high-level output current of -24 mA and a low-level output current of 48 mA at VCC = 4.75 V. Propagation delay times are specified as 15 ns maximum for both tPLH and tPHL under a 300 pF load, and 8 ns maximum under a 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides high-performance bus interface capability for wide data paths or buses carrying parity
• Features pnp inputs designed to reduce DC loading on driving circuits
• Includes power-up high-impedance state to prevent bus contention during initialization

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in computer systems
• Buffering memory address registers
• Wide data path interfacing

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' against the Package Option Addendum to confirm the SOIC package type and tube packaging quantity. Ensure the component meets the required RoHS status and moisture sensitivity level (MSL) ratings for your assembly process. Confirm the operating temperature range aligns with your system's thermal environment specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 10-bit non-inverting buffer with 3-state control is required for ALS logic families. The SN74ALS29827 provides true data, whereas the SN74ALS29828 provides inverted data; ensure the correct polarity matches your design. Consider the 2-input NOR gate control mechanism for OE1 and OE2 pins when designing the enable logic circuitry.
