74HCT241PV-E

Overview

The CD74HCT241PV-E is an octal buffer and line driver manufactured by Renesas Electronics Corporation. It belongs to the HCT series, utilizing CMOS technology for high-speed operation with standard TTL-compatible inputs. The device features two independent four-bit drivers, each equipped with three-state outputs controlled by separate enable inputs. One function has an active-high output enable, while the other has an active-low output enable, allowing flexible bus-oriented configurations. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +85 °C.

Feature Summary

• Octal buffer and line driver architecture providing dual four-bit channels
• Three-state outputs with independent active-high and active-low enables
• CMOS construction ensuring low power consumption and high noise immunity
• TTL-compatible input levels for direct interfacing with standard logic

Applications

• Bus-oriented memory and data register systems
• Clock drivers and buffer circuits
• Bidirectional data transmission gate applications
• High-performance register banks

Procurement Notes

Verify the specific suffix 'PV-E' against the official Renesas datasheet to confirm package type and RoHS compliance status. Ensure the ordering code matches the required temperature grade and packaging format. Cross-reference with the manufacturer's current product availability list to confirm production status before procurement.

Selection Notes

Select this component when an octal buffer with mixed polarity enables is required for bus isolation. The HCT series is suitable for 5 V systems needing TTL compatibility. Consider the HC series if lower power consumption is prioritized over speed, or the AC/ACT series for higher performance requirements in similar packages.

Part Context

This part is part of the widely used 74HCT logic family, designed for 5 V CMOS applications. It serves as a standard solution for driving multiple loads on a shared bus structure. The PV designation typically indicates a plastic small-outline package variant, distinguishing it from DIP or SOIC versions within the same logical function family.

Replacement Considerations

Compatible substitutes include the SN74HCT241 from Texas Instruments and the MC74HCT241 from onsemi. Verify pinout compatibility and electrical specifications such as propagation delay and output drive current before substitution.
