74HC7541DB,118

Overview

The Nexperia 74HC7541DB,118 is an octal Schmitt trigger buffer and line driver housed in a 20-lead SO 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 an ambient temperature range 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-state
• CMOS low power dissipation with high noise immunity
• Input clamp diodes allow current limiting resistor usage for over-voltage interfacing

Applications

• Memory address buffering
• Clock distribution
• Driving bus lines

Procurement Notes

Verify the specific ordering suffix '118' against the manufacturer's latest documentation to confirm the exact packaging configuration and reel specifications. Ensure the design accommodates the SOT163-1 package dimensions and thermal derating requirements specified in the datasheet for reliable operation within the stated temperature limits.

Selection Notes

Select this component when an octal buffer with Schmitt trigger input characteristics is required for noisy environments. The dual output enable pins provide flexible control over the three-state logic levels. Verify that the CMOS input voltage levels align with the driving source logic family before integration into the circuit design.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. The 74HC7541 variant specifically provides eight bits of buffering with Schmitt trigger functionality. It is distinct from the 74HCT7541, which utilizes TTL-compatible input levels instead of standard CMOS thresholds.

Replacement Considerations

The 74HCT7541D,118 is a compatible alternative within the same product family, differing primarily in its TTL-level input compatibility rather than HC-level CMOS inputs.
