74HC241D,652

Overview

The Nexperia 74HC241D,652 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 the SO20 plastic small outline package (SOT163-1). The device provides non-inverting logic with two independent output enable inputs: 1OE (active LOW) and 2OE (active HIGH). Each enable input controls four outputs, allowing configuration as two 4-bit buffers or one 8-bit buffer. Inputs include clamp diodes for interfacing voltages exceeding VCC.

Feature Summary

• Features dual output enables for independent control of two 4-bit groups
• Provides high noise immunity and low power CMOS dissipation
• Includes input clamp diodes for over-voltage tolerance
• Complies with JEDEC standards for ESD protection

Applications

• Octal bus interface systems
• Carry propagation in arithmetic circuits
• Driving capacitive loads on data buses

Procurement Notes

Verify the specific suffix '652' corresponds to the SO20 (SOT163-1) package variant when sourcing. Confirm that the procurement channel supplies production-grade data sheets rather than preliminary specifications. Ensure the component meets the required temperature range of -40 °C to +125 °C for the intended application environment.

Selection Notes

Select this component for designs requiring an 8-bit non-inverting buffer with tri-state capability. It is suitable for applications needing separate enable control for two halves of the bus. Verify that the system voltage falls within the 2.0 V to 6.0 V operating range and that the load capacitance requirements are met by the specified dynamic characteristics.

Part Context

This part belongs to the 74HC/HCT logic family, designed for general-purpose digital applications. The 'D' designation indicates the SO20 surface-mount package. It serves as a standard interface component for connecting microprocessors, memory devices, and other logic circuits where bus isolation or signal buffering is required.

Replacement Considerations

The 74HCT241D,652 is functionally compatible but requires a 4.5 V to 5.5 V supply. Other packages like TSSOP20 (PW suffix) offer pin-compatible alternatives if board space constraints differ.
