74HCT7541N,112

Overview

The NXP USA Inc. 74HCT7541N,112 is an octal Schmitt trigger buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device includes two active-low output enable inputs (OE1 and OE2) that force the outputs into a high-impedance state when asserted. Inputs are equipped with clamp diodes to allow interfacing with voltages exceeding VCC using current-limiting resistors. The component provides non-inverting logic functionality.

Feature Summary

• Features Schmitt trigger inputs to transform slowly changing signals into sharply defined jitter-free outputs
• Includes dual active-low output enables for flexible bus management and high-impedance control
• Integrates input clamp diodes to facilitate safe interfacing with higher voltage levels

Applications

• Bus-oriented memory and address drivers
• Clock buffering and distribution circuits
• Transmitting data across multiple receivers

Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and compliance standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust noise immunity due to its Schmitt trigger input characteristics. It is suitable for applications needing simultaneous driving of multiple loads via its eight independent channels. Verify that the system logic levels align with the specified TTL input thresholds for optimal performance.

Part Context

This part belongs to the 74HCT series of CMOS logic devices manufactured by Nexperia under license from NXP. It serves as an octal buffer within the broader family of standard logic integrated circuits designed for general-purpose digital signal processing and interface applications.

Replacement Considerations

Direct replacements include the 74HC7541 variants or other octal buffers with identical pinouts and electrical characteristics. Verify compatibility regarding propagation delay and output drive strength when substituting with components from different manufacturers.
