SN74ALS29827DWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29827DWRG4 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 provides high-performance bus interface capabilities for wide data paths or parity-carrying buses. It features pnp inputs that reduce DC loading and utilizes a data flow-through pinout configuration where all inputs are positioned on the opposite side from the outputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two independent output-enable inputs (OE1, OE2) configured as a NOR gate to control the 3-state outputs
• Provides true data transmission at the respective outputs
• Includes power-up high-impedance state functionality
• Utilizes pnp input technology to minimize DC loading

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the RoHS compliance status and lead finish material (NIPDAU) against specific project requirements. Confirm the Moisture Sensitivity Level (MSL 1) and peak reflow temperature limits before assembly. Ensure the SOIC-24 package dimensions align with the printed circuit board layout constraints. Validate the active production status directly with the manufacturer prior to finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 10-bit non-inverting buffering with dual independent enable controls. The ALS logic family offers distinct switching characteristics compared to standard TTL or BCT families. Verify that the required propagation delay and output drive currents meet the system's electrical specifications. Consider the physical pinout arrangement if space constraints dictate input-output separation.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the output-enable control mechanism work?

The device uses a 2-input NOR gate for the output-enable control. If either OE1 or OE2 input is high, all ten outputs enter a high-impedance state.

What is the maximum low-level output current?

The recommended operating conditions specify a maximum low-level output current (IOL) of 48 mA.
