74HC241DB,118

Overview

The Nexperia 74HC241DB,118 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 supports ambient temperatures from -40 °C to +125 °C. The device provides non-inverting logic with two independent output enable inputs (1OE active LOW, 2OE active HIGH) controlling four outputs each. It complies with JEDEC standards JESD8C and JESD7A, includes input clamp diodes for overvoltage interfacing, and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Features dual output enables allowing configuration as one 8-bit or two 4-bit buffers.
• Provides high noise immunity and low power dissipation typical of CMOS technology.
• Includes input clamp diodes enabling interface to voltages exceeding the supply rail using current limiting resistors.
• Delivers robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Applications

• Octal bus interface systems requiring signal buffering.
• Line driving applications in industrial control environments.
• Mixed voltage logic interfacing utilizing input clamp diodes.

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the SSOP-20 package variant during procurement. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design safeguards account for the absolute maximum ratings regarding supply voltage and output currents to prevent permanent device damage.

Selection Notes

Select this component when an octal buffer with independent tri-state control is required. The 74HC241 is suitable for general-purpose digital logic applications where CMOS input levels are utilized. Consider the 74HCT241 variant if TTL input level compatibility is necessary instead of standard CMOS thresholds.

Part Context

This part belongs to the 74HC/HCT logic family manufactured by Nexperia. It functions as an octal buffer/line driver with 3-state outputs. The device can be configured as two separate 4-bit buffers or a single 8-bit buffer depending on the state of the output enable pins.

Replacement Considerations

The 74HC241PW,118 serves as a pin-compatible alternative housed in a TSSOP-20 package. Verify package dimensions and thermal characteristics when substituting between SO20 and TSSOP20 variants.
