74HC283FP-E

Overview

The CD74HC283FP-E is a high-speed CMOS 4-bit binary full adder manufactured by Renesas Electronics Corporation. It utilizes silicon gate C2MOS technology to provide fast propagation delays and low power dissipation. The device features symmetrical output impedance and balanced propagation delays, ensuring reliable signal integrity. It operates within a wide voltage range of 2V to 6V and offers high noise immunity. The component includes full-carry look-ahead across all four bits, combining speed with the economy of ripple carry for partial look-ahead applications.

Feature Summary

• High-speed operation utilizing silicon gate C2MOS technology
• Full-carry look-ahead functionality across four bits
• Wide operating voltage range supporting 2V to 6V supply
• High noise immunity with symmetrical output impedance

Applications

• Digital arithmetic logic units
• Address decoding circuits
• Counting and timing systems

Procurement Notes

Verify the specific suffix 'FP-E' against official Renesas documentation to confirm package type and environmental compliance status. Ensure the ordering part number matches the exact die revision and lead finish requirements for your assembly process. Cross-reference with the manufacturer's current datasheet to validate active status and any recent design changes.

Selection Notes

Select this component when a 4-bit binary addition function is required in CMOS logic designs. It serves as a direct pin-compatible replacement for standard 74LS283 equivalents where lower power consumption and higher speed are necessary. Consider the 2V to 6V operating range for compatibility with various logic families.

Part Context

This device belongs to the HC (High-speed CMOS) logic family, which bridges the performance gap between standard TTL and older CMOS technologies. The 74HC283 series provides improved switching speeds while maintaining low static power dissipation. It is designed for general-purpose digital applications requiring reliable binary arithmetic operations.

Replacement Considerations

Compatible substitutes include the M74HC283 from STMicroelectronics and the HD74HC283 from Renesas. Verify pinout compatibility and electrical specifications before substitution.
