SN74LVC828APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC828APW is a 10-bit buffer and bus driver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V. The device provides inverting data at its outputs and features two active-low output-enable inputs (OE1, OE2) that function as a 2-input AND gate; if either input is high, all ten outputs enter a high-impedance state. It supports mixed-mode signal operation, allowing 5-V input/output voltage compatibility while powered by a 3.3-V VCC. The package is TSSOP-24.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation on all ports for interfacing between 5-V and 3.3-V devices
• Includes Ioff circuitry to support partial-power-down mode and prevent damaging current backflow
• Features dual active-low output-enable inputs controlling the 3-state outputs

Buffers, Drivers, Receivers, Transceivers Applications

• Wide data path bus interfaces
• Buses carrying parity information
• Mixed 3.3-V/5-V system environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP package with a tube quantity of 60 units. Confirm the operating temperature range is -40°C to +85°C. Ensure the RoHS status and lead finish match project requirements. Check for any recent Product Change Notices affecting availability or specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 10-bit inverting buffer with 3-state control is required for low-voltage logic applications. The LVC series ensures compatibility with standard CMOS logic levels. Verify that the maximum propagation delay meets the timing constraints of the target bus architecture. Consider the thermal impedance characteristics of the TSSOP package for the intended enclosure design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC828A family of 10-bit buffers/drivers. It is designed for high-performance bus interface applications requiring wide data paths. The device is distinct from non-inverting buffers or single-ended drivers due to its specific 10-bit width and dual enable functionality.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial-power-down scenarios?

The SN74LVC828APW includes Ioff circuitry that automatically disables the outputs when the device is powered down, preventing damaging current backflow through the device.

What is the logic function of the output-enable pins?

The OE1 and OE2 inputs act as a 2-input AND gate with active-low polarity. If either OE1 or OE2 is high, all ten outputs are placed in the high-impedance state.
