74AHC9541APWJ

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC9541APWJ is an octal buffer and line driver featuring 3-state outputs and Schmitt trigger inputs. It operates within a supply voltage range of 1.8 V to 5.5 V. The device includes an output enable input (OE) and a select input (S), where a HIGH on OE forces outputs to a high-impedance state, and a LOW on S configures the circuit as an inverter. Propagation delay ranges from 3.4 ns to 5.7 ns depending on voltage and load. It supports mixed-mode voltage operation and includes IOFF circuitry for partial power-down applications.

• Partial power-down mode operation in battery-powered systems
• Octal buffering and line driving in digital communication interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PWJ' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the TSSOP20 package dimensions align with your PCB footprint design rules before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with configurable inversion and 3-state control is required. The inclusion of Schmitt triggers makes it suitable for noisy environments or slow signal edges. Verify that the operating temperature range of -40 °C to +125 °C meets your environmental constraints and that the supply voltage range covers your system's power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC9541A family of octal buffers and line drivers manufactured by Nexperia. It is designed for high-speed digital applications requiring multiple buffered channels with independent control capabilities. The device utilizes advanced CMOS technology to achieve low power consumption while maintaining robust performance across a wide voltage range.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the same 74AHC series. Verify functional equivalence regarding propagation delay, output drive strength, and control logic polarity. Ensure any replacement maintains the same TSSOP20 package and thermal characteristics.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Select (S) input affect the logic function?

When the Select (S) input is LOW, the buffer acts as an inverter. When S is HIGH, the buffer operates in its standard non-inverting mode.

What is the purpose of the IOFF circuitry?

The IOFF circuitry disables the outputs when the device is powered down, preventing damaging backflow current through the device in partial power-down applications.
