74HC241D,653

Overview

The Nexperia 74HC241D,653 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes CMOS technology for low power dissipation. The device contains two independent output enable inputs (1OE active LOW and 2OE active HIGH), allowing control over four outputs each. It complies with JEDEC standards JESD8C and JESD7A. The component is housed in a 20-lead SO plastic small outline package (SOT163-1) and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides non-inverting octal bus interface capability with high noise immunity
• Features dual output enables that independently control separate groups of three-state outputs
• Includes input clamp diodes to facilitate interfacing with voltages exceeding the supply rail

Applications

• Octal bus interface systems
• Carry propagation in wide arithmetic logic units
• Driving bus lines across multiple loads

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers both SO and TSSOP variants. Confirm the temperature grade aligns with system requirements, noting the specified range extends to +125 °C. Ensure design compliance with ESD protection specifications and latch-up performance limits defined in the official datasheet before finalizing procurement.

Selection Notes

Select this component when an eight-bit non-inverting buffer with tri-state control is required. The 74HC241D variant specifically targets applications needing operation across a wide voltage spectrum up to 6.0 V. Consider the physical dimensions of the SOT163-1 package during layout planning. Verify that input signal levels conform to CMOS standards rather than TTL thresholds.

Part Context

This device belongs to the 74HC family of high-speed CMOS logic products manufactured by Nexperia. It serves as a standard solution for digital buffering and line driving tasks in mixed-voltage environments. The product adheres to established JEDEC industry standards for logic integrated circuits, ensuring compatibility with broader system designs.

Replacement Considerations

The 74HCT241D is a compatible alternative within the same series offering TTL-compatible input levels. Designers must verify that input voltage thresholds match the new selection if replacing the HC version with the HCT version.
