SN74HCS541RKSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCS541RKSR is an octal buffer and line driver featuring Schmitt-trigger inputs and three-state outputs. It operates within a supply voltage range of 2 V to 6 V, supporting extended ambient temperatures from -40°C to +125°C. The device provides balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. It utilizes a 20-pin VQFN package with dimensions of 4.50 mm by 2.50 mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow or noisy input signals
• Balanced CMOS three-state outputs allow active driving of high/low states and high-impedance control
• Dual active-low output enable pins (OE1 and OE2) must both be low to activate all channels

Buffers, Drivers, Receivers, Transceivers Applications

• Enable or disable digital signals in bus architectures
• Eliminate slow or noisy input signals through hysteresis filtering
• Hold signal states during controller reset sequences
• Switch debounce applications requiring stable logic transitions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific RKS suffix indicates the VQFN-20 package configuration. Confirm RoHS compliance status via official documentation. Ensure design compatibility with the specified 2V to 6V operating voltage range and -40°C to +125°C temperature limits before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when Schmitt-trigger noise rejection is required for octal buffering. The dual enable pin architecture offers flexible control logic compared to single-enable devices. Verify that the VQFN-20 footprint matches the PCB layout constraints and thermal requirements for the target application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74HCS541 family of octal buffers. It shares functional similarities with other HCS series drivers but is distinguished by its specific Schmitt-trigger input characteristics and flow-through pinout configuration designed for efficient board routing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74HCS541RKT and SN74HCS541DGS. Verify package compatibility and electrical specifications match before substitution.

Buffers, Drivers, Receivers, Transceivers FAQ

How do the dual output enable pins function?

Both OE1 and OE2 must be held low for the outputs to become active. If either pin is high, all outputs enter the high-impedance state.

What is the benefit of Schmitt-trigger inputs?

They provide hysteresis, allowing the device to tolerate slow input transition rates and reject noise without causing oscillation or excessive power consumption.
