74HC7541N,112

Overview

The 74HC7541N,112 is an octal buffer and line driver manufactured by NXP Semiconductors. It features Schmitt-trigger inputs and three-state outputs controlled by two active LOW enable signals (OE1 and OE2). The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. It is housed in a DIP20 plastic dual in-line package with 20 leads.

Feature Summary

• Non-inverting logic function
• Schmitt trigger input filtering for jitter-free output
• Dual independent output enables for high-impedance control
• Input clamp diodes for voltage interface flexibility

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory address and data register drivers

Procurement Notes

Verify the specific ordering code 74HC7541N,112 against current NXP documentation to confirm availability and package specifications. Ensure design compliance with JEDEC standard no. 7A requirements. Confirm that the DIP20 package thermal derating characteristics align with the intended operating environment and power dissipation limits.

Selection Notes

Select this component when an octal non-inverting buffer with Schmitt-trigger noise immunity is required. The presence of two separate output enables allows for flexible bus management. Verify that the CMOS input levels are compatible with the driving source logic family.

Part Context

This part belongs to the 74HC series of high-speed silicon-gate CMOS logic devices. It is pin-compatible with low-power Schottky TTL (LSTTL) standards. The device is specified in compliance with JEDEC standard no. 7A, ensuring interoperability within standard digital logic families.

Replacement Considerations

The 74HCT7541N variant serves as a functional replacement if TTL-level input compatibility is required instead of CMOS levels. Other package options such as SO20 or SSOP20 exist but require footprint adaptation.
