74HC7541PW,118

Overview

The Nexperia 74HC7541PW,118 is an octal Schmitt trigger buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and accepts CMOS input levels. The device includes two active-low output enable inputs (OE1 and OE2) that force outputs into a high-impedance state when asserted. Inputs are equipped with clamp diodes for interfacing with voltages exceeding VCC. It is housed in a 20-lead TSSOP package (SOT360-1) and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Schmitt trigger inputs convert slowly changing signals into sharply defined jitter-free outputs
• Dual independent output enables control three-state logic levels
• Input clamp diodes allow safe interfacing with voltages higher than the supply rail

Applications

• Memory address buffering
• Clock distribution networks
• Data bus driving applications

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel or cut-tape configuration. Confirm the package variant corresponds to the SOT360-1 designation. Ensure the component meets RoHS3 compliance requirements for your manufacturing process. Check for any recent Product Change Notices regarding marking or assembly updates.

Selection Notes

Select this component when eight-channel non-inverting buffering with noise immunity is required. The Schmitt trigger action is essential for noisy environments or slow signal edges. Verify that the 2.0 V to 6.0 V supply range aligns with the system power architecture. Consider the TSSOP footprint constraints during PCB layout planning.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It serves as an octal version of single-bit buffers, providing significant integration for parallel data paths. The family is designed for general-purpose digital applications requiring robust noise rejection and flexible output control.

Replacement Considerations

Direct functional equivalents include other 74HC7541 variants from different manufacturers. Cross-reference pinouts and electrical characteristics carefully. Automotive qualified versions exist under separate part numbers if AEC-Q100 certification is mandatory.
