74LVC823AD,112

Overview

The 74LVC823AD,112 is a dual 4-bit parallel adder with carry-in and carry-out manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.65V to 3.6V and supports an operating temperature from -40°C to +85°C. The device features a propagation delay of 19ns at 3.3V with 50pF load and provides output drive currents of 24mA for both high and low states. Packaged in a 20-SOIC (0.295" width) surface-mount format, it complies with JEDEC standards JESD8-7A and JESD8-5A.

Feature Summary

• Performs arithmetic addition of two 4-bit binary words with independent carry-in and carry-out control
• Provides direct interface compatibility with TTL logic levels across the specified voltage range
• Includes Schmitt-trigger action on all inputs to ensure tolerance against slow rise and fall times

Applications

• Digital arithmetic processing units requiring parallel addition
• Address calculation circuits in embedded systems
• Data path management in microcontroller-based designs

Procurement Notes

Verify the specific suffix '112' corresponds to the requested tape-and-reel packaging configuration. Confirm that the 20-SOIC package dimensions align with the target PCB footprint. Ensure the -40°C to +85°C industrial temperature rating meets the operational environment requirements. Cross-reference the JEDEC compliance status with current regulatory standards before finalizing procurement.

Selection Notes

Select this component when a dual 4-bit adder function is required within a single package. It is suitable for applications needing direct TTL interfacing without additional level shifting. Consider the 19ns propagation delay for timing constraints. Evaluate the 20-SOIC package size against available board space compared to smaller alternatives like QFN or TSSOP variants if pin count permits.
