74HC7541D,112

Overview

The Nexperia 74HC7541D,112 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 includes two active-low output enable inputs (OE1 and OE2). The device utilizes SO20 plastic small outline packaging (SOT163-1) with a body width of 7.5 mm. Inputs incorporate clamp diodes for interfacing with voltages exceeding VCC. It supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• Dual active-low output enables control high-impedance OFF-state
• Input clamp diodes allow interface to voltages exceeding VCC using current limiting resistors

Applications

• Buffering digital data lines
• Driving transmission lines
• Interface circuits requiring noise immunity

Procurement Notes

Verify the ordering suffix matches the required package type. Confirm RoHS compliance status through official documentation. Ensure the specific revision level aligns with design requirements. Check for any recent product change notices affecting marking or assembly.

Selection Notes

Select this component when eight buffered channels with Schmitt trigger action are required. Verify that the CMOS input levels match the source logic family. Ensure the operating voltage falls within the specified 2.0 V to 6.0 V range. Confirm thermal dissipation limits suit the application environment.

Part Context

This part belongs to the 74HC series of logic integrated circuits manufactured by Nexperia. It is functionally compatible with other octal buffers in the same family but distinguished by its specific Schmitt trigger characteristics and three-state output capability. The D suffix indicates the SO20 package variant.

Replacement Considerations

Substitutes must maintain the 74HC logic family specifications and SO20 package footprint. Verify equivalent propagation delay and power dissipation ratings. Ensure the replacement device also features dual output enables and Schmitt trigger inputs.
