74HC283PW,112

Overview

The 74HC283PW,112 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 ranging from 15 ns to 240 ns depending on voltage and temperature conditions. It utilizes a 16-lead TSSOP package (SOT403-1) compliant 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 expanded 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

• Binary arithmetic logic units requiring 4-bit summation
• Cascaded multi-bit adder configurations
• 5-input encoder implementations using equally weighted inputs
• 5-input majority gate circuits

Procurement Notes

Verify the specific ordering suffix and package variant against current NXP documentation, as manufacturing status may have changed. Confirm that the TSSOP16 form factor matches your PCB footprint requirements. Check for any recent product change notifications or end-of-life declarations directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 4-bit binary full adder with fast carry is required in a surface-mount TSSOP16 package. Ensure the operating environment stays within the specified -40 °C to +125 °C temperature range. Verify that the 2.0 V to 6.0 V supply voltage aligns with your system's power rails. Consider cascading capabilities if larger bit-width addition is needed.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is pin-compatible with low power Schottky TTL (LSTTL) standards, facilitating integration into legacy systems. The device performs binary addition of two 4-bit words plus an incoming carry, outputting the sum and outgoing carry.

Replacement Considerations
