CD74HC670M Texas Instruments Integrated Circuit (Small Outline Packages) In Stock

What are the key features of CD74HC670M?

• 4x4 register file architecture with independent read and write address buses enables simultaneous read and write to different register locations, supporting high-throughput data buffering without pipeline stalls
• Parallel-in parallel-out (PIPO) data path with 4-bit width and four register locations provides a small, fast scratch-pad memory for storing intermediate computation results in digital logic systems
• 23MHz maximum operating frequency at nominal supply voltage with HC-family CMOS low-power consumption makes it suitable for high-speed digital glue logic, address decoding, and register-based state machines
• Wide 2V to 6V supply range in a 16-pin SOIC package ensures compatibility with 3.3V and 5V digital systems in a compact, industry-standard surface-mount footprint

What is CD74HC670M used for?

The CD74HC670M serves as a fast scratch-pad register file in digital systems where multiple intermediate data values must be stored and accessed simultaneously without the latency of external SRAM, such as in arithmetic logic units, data path controllers, and FPGA glue-logic expansions. It is used in communication protocol processors to buffer register state across multiple bus cycles and in industrial control systems for storing sensor channel configuration values accessible by both a processor bus and local combinational logic. The device also appears in educational digital design courses as an example of a small multi-port memory element implemented with CMOS register file technology.
