74HC283PW,118

Overview

The 74HC283PW,118 is a high-speed Si-gate CMOS 4-bit binary full adder with fast carry, manufactured by NXP USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features propagation delays up to 48 ns at 4.5 V and 41 ns at 6.0 V under standard load conditions. It utilizes a 16-lead TSSOP package (SOT403-1) and complies with JEDEC standard no. 7A.

Feature Summary

• High-speed 4-bit binary addition with fast internal look-ahead carry
• Cascadable in 4-bit increments for extended arithmetic operations
• Low-power dissipation characteristics suitable for energy-efficient designs
• ESD protection exceeding 2000 V per HBM and 200 V per MM standards

Applications

• Implementing multi-bit binary addition circuits
• Constructing 5-input encoders with equally weighted inputs
• Designing 5-input majority gates for logic decision making
• Creating cascaded adder systems for complex arithmetic processing

Procurement Notes

Verify the specific ordering suffix and package variant against current manufacturer documentation, as product status may change. Confirm RoHS compliance and REACH status requirements for your region. Check for any recent Product Change Notifications that might affect pin compatibility or electrical specifications before finalizing procurement.

Selection Notes

Select this component when a high-speed CMOS solution is required for 4-bit binary addition. Ensure the operating voltage aligns with the 2.0 V to 6.0 V range. Consider the TSSOP16 package constraints for PCB layout. Verify that the input/output voltage levels are compatible with the rest of the system logic family.

Part Context

This device belongs to the 74HC series of high-speed CMOS logic devices. It is pin-compatible with low power Schottky TTL (LSTTL), facilitating migration from older technologies. The 74HC283 specifically handles 4-bit addition, differing from other members like the 74HC74 flip-flop or 74HC238 decoder which serve different logical functions.

Replacement Considerations

Public confirmed substitute part numbers include 74HC283PW-T.
