74HC7541D,118

Overview

The Nexperia 74HC7541D,118 is an octal Schmitt trigger buffer and line driver housed in a 20-lead SO20 plastic small outline package (SOT163-1). It features non-inverting outputs with three-state capability controlled by two active LOW output enable inputs. The device operates on a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Schmitt trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• Dual active LOW output enables control high-impedance OFF-states
• Input clamp diodes allow current limiting resistor usage for over-voltage interfacing

Applications

• Buffering digital data lines
• Line driving applications requiring noise immunity
• System interface buffering with slow signal transitions

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the standard tape-and-reel packaging configuration. Confirm that the SO20 package variant matches the required PCB footprint dimensions. Ensure the design accounts for the specified power dissipation derating curves above 109 °C to maintain reliability within the stated temperature limits.

Selection Notes

Select this component when designing systems requiring eight buffered channels with Schmitt trigger input characteristics. The dual enable pins provide flexible control logic for bus sharing or tri-state management. Verify that the CMOS input levels are compatible with the source logic family driving the A0 through A7 inputs.

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 consolidated signal conditioning for parallel data buses. The device is designed for general-purpose digital applications where noise immunity and low power consumption are prioritized.

Replacement Considerations

The 74HCT7541D,118 is available as a TTL-level compatible alternative within the same package. Cross-reference with other manufacturers' octal Schmitt trigger buffers if pinout compatibility is required.
