74HC241PW,118

Overview

The Nexperia 74HC241PW,118 is an octal buffer and line driver featuring three-state outputs, housed in a TSSOP20 (SOT360-1) package. 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) controls four outputs, while 2OE (active HIGH) controls the other four. Inputs include clamp diodes for interfacing voltages exceeding VCC.

Feature Summary

• Features dual output enables (1OE and 2OE) allowing independent control of two groups of four three-state outputs each.
• Includes input clamp diodes enabling safe interface to voltages higher than the supply voltage using current limiting resistors.
• Complies with JEDEC standards JESD8C and JESD7A for robust performance across specified voltage ranges.
• Provides high electrostatic discharge protection exceeding 2000 V under Human Body Model testing.

Applications

• Octal bus interface systems
• Driving capacitive loads in digital circuits
• Memory address and data bus buffering

Selection Notes

Select this component when designing systems requiring an 8-bit non-inverting buffer with split output enable capabilities. Ensure the application voltage remains within the 2.0 V to 6.0 V range and that the TSSOP20 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It serves as a standard solution for expanding drive capability on digital buses, offering low power dissipation and high noise immunity compared to older logic families.

Replacement Considerations

The 74HCT241PW,118 is a compatible alternative within the same family, distinguished by TTL-compatible input thresholds suitable for 5 V logic interfaces.

FAQ

How are the outputs disabled?

Outputs are placed in a high-impedance OFF-state when 1OE is set to HIGH or when 2OE is set to LOW.

Can the inputs handle voltages above VCC?

Yes, the inputs feature clamp diodes that allow connection to voltages exceeding VCC, provided a current-limiting resistor is used.
