74HCT241D,652

Overview

The Nexperia 74HCT241D,652 is an octal buffer and line driver with three-state outputs belonging to the HCT logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and features TTL-compatible input levels for interfacing with standard logic systems. The device provides non-inverting 3-state outputs controlled by two independent output enable signals. It includes input clamp diodes to facilitate current-limiting resistor usage for voltages exceeding VCC. The component is specified for operation from -40 °C to +85 °C and -40 °C to +125 °C, ensuring reliability across industrial temperature ranges.

Feature Summary

• Octal bus interface with non-inverting 3-state outputs
• TTL-compatible input levels for direct logic interfacing
• Dual output enables controlling four outputs each
• Input clamp diodes for overvoltage protection

Applications

• Octal bus interface systems
• Industrial control applications
• Telecommunications infrastructure

Procurement Notes

Verify end-of-life status before design finalization as availability may be restricted. Confirm package dimensions and thermal characteristics against PCB layout requirements. Ensure supply voltage compatibility with target system rails. Validate ESD protection ratings for specific environmental conditions. Check distributor stock levels for immediate procurement needs.

Selection Notes

Select this component when an octal buffer with three-state capability is required for bus applications. Choose the HCT variant specifically for TTL-level input compatibility in mixed-voltage environments. Consider the wide operating temperature range for harsh industrial settings. Verify that the dual enable structure fits the system's control logic architecture.

Part Context

This part belongs to the Nexperia 74HCT series, designed for high-speed CMOS logic with TTL-compatible inputs. The 74HCT241D variant specifically offers octal buffering with tri-state outputs, distinguishing it from unidirectional drivers or non-tri-state buffers. It complements other bus transceivers like the 74HCT245 but lacks bidirectional direction control.

Replacement Considerations

The 74HCT241D,653 is listed as a parameter-equivalent alternative by Nexperia. Verify pinout and electrical specifications match exactly before substitution. Other manufacturers' equivalents require careful validation of input thresholds and output drive capabilities.
