74HCT241DB,118

Overview

The Nexperia 74HCT241DB,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes the SO20 plastic small outline package (SOT163-1) with a body width of 7.5 mm. It includes two output enable inputs: 1OE (active LOW) and 2OE (active HIGH), allowing independent control of four outputs each. The component provides non-inverting logic levels compatible with TTL input thresholds.

Feature Summary

• Features two independent output enable inputs for controlling separate groups of three-state outputs
• Provides non-inverting signal buffering suitable for bus interface applications
• Includes input clamp diodes to facilitate interfacing with voltages exceeding the supply rail

Applications

• Octal bus interface systems
• Line driving for digital signals
• Buffering between different logic families

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the standard tape-and-reel packaging configuration defined in the official datasheet. Confirm that the SO20 package variant matches the required PCB footprint dimensions. Ensure the procurement channel sources genuine Nexperia components to guarantee compliance with the specified electrical characteristics and temperature ratings.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS performance. The dual enable structure allows flexible partitioning of the eight outputs. Verify that the application environment remains within the specified -40 °C to +125 °C operating range. Consider the power dissipation limits and thermal derating requirements for the SO20 package during high-load conditions.

Part Context

This part belongs to the 74HCT series of hex/octal logic devices manufactured by Nexperia. It serves as the HCT-compatible version of the 74HC241, specifically designed to interface directly with Transistor-Transistor Logic (TTL) circuits while maintaining low power consumption. The device is widely used in general-purpose digital electronics requiring robust signal buffering.

Replacement Considerations

The 74HC241D,118 offers identical pinout and functionality but uses CMOS input thresholds instead of TTL levels. Other manufacturers produce equivalent octal buffers with three-state outputs; verify voltage ranges and package compatibility before substitution.
