SN74LVC828APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC828APWT 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 and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation in 5-V input/output environments with a 3.3-V VCC. The device provides an inverting data path at its outputs and utilizes two active-low output-enable (OE1 and OE2) inputs configured as a 2-input AND gate. It supports partial-power-down mode via Ioff circuitry and includes ESD protection exceeding JESD 22 standards.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the specific suffix requirements for your assembly process. The APWT suffix indicates a TSSOP package variant supplied in a small tape and reel format. Confirm the operating temperature range aligns with your design specifications before procurement. Ensure all unused inputs are properly terminated to maintain device functionality.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 10-bit data buffering with mixed-voltage compatibility between 3.3-V and 5-V logic levels. The dual active-low output enable inputs provide flexible control over the 3-state outputs. Consider the low static power consumption and high-speed propagation characteristics suitable for general-purpose digital applications within the specified voltage range.

Buffers, Drivers, Receivers, Transceivers FAQ

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

The device incorporates Ioff circuitry that disables the outputs when powered down, preventing damaging current backflow through the device.

What is the function of the OE1 and OE2 inputs?

OE1 and OE2 are active-low output-enable inputs that function as a 2-input AND gate; if either input is high, all ten outputs enter the high-impedance state.
