74ALVC541BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVC541BQ,115 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V and includes Schmitt trigger inputs for noise tolerance. The device incorporates IOFF circuitry to prevent backflow current during partial power-down states. It utilizes the DHVQFN20 package (SOT764-1) with dimensions of 2.5 mm by 4.5 mm. Propagation delay ranges from 1.0 ns to 5.3 ns depending on voltage. Latch-up performance exceeds 250 mA per JESD78 Class II.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two active LOW output enable inputs (OE0 and OE1) for independent control of high-impedance OFF-states.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents when the device is powered down.
• Schmitt trigger action on all inputs provides high tolerance for slow rise and fall times.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode applications requiring protection against backflow current
• Octal bus driving and buffering in low-voltage systems
• Interfaces between TTL logic levels and CMOS devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '115' corresponds to the DHVQFN20 package variant SOT764-1. Confirm that the required temperature range aligns with the -40 °C to +125 °C specification. Ensure design compatibility with the 1.65 V to 3.6 V supply voltage limits. Check for any recent Product Change Notifications regarding package or material updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring eight buffered channels with independent tri-state control. The DHVQFN20 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the IOFF feature if the system involves hot-swap scenarios or partial power domains. Verify input transition rates against the recommended operating conditions for the target supply voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ALVC541 family of octal buffers. The BQ suffix specifically denotes the DHVQFN20 plastic dual in-line compatible thermal enhanced very thin quad flat package. Other variants in the series include SO20 and TSSOP20 packages, offering flexibility for different thermal and spatial requirements.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74ALVC541 variants such as 74ALVC541D or 74ALVC541PW if package differences are acceptable. Cross-brand equivalents must match the 8-bit tri-state configuration, 1.65 V to 3.6 V supply range, and DHVQFN20 footprint.
