What are the key features of CD74ACT283M?
- 4-bit binary full adder with internal carry lookahead for fast arithmetic operations in digital logic designs
- ACT logic family compatible with 50 pF load capacitance, balancing speed and drive strength in bus applications
- 16-pin SOIC (R-PDSO-G16) surface-mount package for compact PCB integration in high-density digital boards
What is CD74ACT283M used for?
The CD74ACT283M is used in digital arithmetic units, ALU datapaths, and binary counter circuits where fast 4-bit addition with carry propagation is required. Its ACT logic compatibility and 75 mA output drive current make it suitable for bus-connected addition stages in FPGAs, DSP co-processors, and real-time control systems that demand low-latency binary arithmetic with standard TTL-compatible interfaces.

Frequently Asked Questions
How does the internal carry lookahead in CD74ACT283M improve addition speed compared to ripple-carry adders?
The CD74ACT283M uses internal carry lookahead logic that computes carry signals in parallel rather than waiting for each bit to propagate serially. This reduces worst-case addition latency compared to a ripple-carry design, making it suitable for 4-bit arithmetic units in real-time digital systems where tight timing budgets at ACT logic speeds with 50 pF load capacitance apply.
What is the maximum output current I(ol) rating of CD74ACT283M, and why does it matter for bus-connected designs?
The CD74ACT283M specifies a maximum low-level output current I(ol) of 75 mA. This strong sink capability allows it to drive multiple bus loads reliably without violating logic thresholds, making it a good fit for shared bus lines on digital PCBs where several devices present simultaneous load capacitances up to 50 pF per output.
In which package does the CD74ACT283M ship, and how many pins does it provide?
The CD74ACT283M comes in a 16-pin small-outline SOIC package (JESD-30 code R-PDSO-G16). The 16-pin format accommodates the 4-bit data inputs, 4-bit sum outputs, carry-in, carry-out, and power pins while keeping the PCB footprint compact enough for dense digital logic boards and prototyping applications.
When is CD74ACT283M a practical alternative to implementing 4-bit addition inside an FPGA fabric?
Designers choose the CD74ACT283M as an external discrete adder when FPGA logic resources are fully utilized or when the arithmetic path runs at ACT logic speeds outside the programmable device. Using a dedicated 4-bit full adder with 75 mA drive and 50 pF load handling offloads the addition from the programmable fabric and can simplify board-level timing closure in mixed-logic systems.
