Frequently Asked Questions
What is the CD54HC174F and what does it do?
The CD54HC174F is a CMOS 6-Bit D Flip-Flop from Texas Instruments in the HC/UH logic family. It stores six bits of data on the rising clock edge, and all flip-flops share a common clock and an active-low master reset. It operates at clock frequencies up to 20 MHz and is designed for synchronous register and latch applications.
What package does the CD54HC174F come in?
The CD54HC174F is housed in a 16-pin Ceramic Dual In-Line Package (CERDIP), with JESD-30 code R-GDIP-T16. The ceramic package provides superior moisture resistance and thermal performance compared to plastic DIP variants, making it suitable for military, aerospace, and industrial high-reliability applications.
What is the maximum operating frequency of the CD54HC174F?
The CD54HC174F supports a maximum clock frequency of 20 MHz at nominal supply voltage with a 50 pF load capacitance. This makes it suitable for moderate-speed synchronous digital designs including state machines, pipeline registers, address latches, and data buffers in embedded systems.
Is the CD54HC174F RoHS compliant?
The CD54HC174F carries a Pb-free code of 'Yes' but has a JESD-609 code of e0, which is associated with ceramic hermetic packages where solder termination materials may differ from standard Pb-free surface-mount devices. Verify compliance documentation with Texas Instruments for specific regulatory requirements before use in restricted applications.
What are common applications for the CD54HC174F?
The CD54HC174F is commonly used in synchronous data registers, address latches, state machine storage, and pipeline stages in digital logic systems. Its ceramic DIP packaging and 20 MHz clock capability make it especially popular in military electronics, test equipment, and industrial control systems requiring long-term reliability and environmental robustness.
