What are the key features of CD74HC195EG4?
- 4-bit parallel-load shift register with both J/K and serial (D-type) serial input modes
- Synchronous clear and parallel load in a single clock cycle for fast register initialization
- Wide 2 V to 6 V supply range compatible with TTL and 3.3 V CMOS logic families
- 16-pin DIP package for breadboard prototyping and through-hole PCB assembly
What is CD74HC195EG4 used for?
The CD74HC195EG4 is used in digital systems requiring temporary data storage, serial-to-parallel conversion, or bit manipulation—such as SPI protocol converters, data pipelines, and sequence generators in embedded control boards. Its parallel load feature enables rapid register pre-loading within a single 20 MHz clock cycle, making it suitable for synchronous state-machine designs. The through-hole DIP package simplifies prototyping and repair in low-volume industrial and educational applications.

Frequently Asked Questions
What serial input modes does the CD74HC195EG4 support, and how do they differ in a shift-register application?
The CD74HC195EG4 provides two serial input modes: a J/K mode that allows set, reset, or toggle of each incoming bit, and a D-type (J=D, K=D̄) mode for straightforward serial shift. In a 4-bit SIPO converter clocked at 10 MHz, the D-type mode passes one bit per clock, shifting all 4 bits in 400 ns, while J/K mode enables more complex bit-pattern generation without external logic.
How does the synchronous clear feature of the CD74HC195EG4 simplify initialization in a digital control system?
The active-low synchronous clear resets all 4 outputs to logic 0 on the next rising clock edge without disrupting the clock tree. In a motor sequencer clocked at 5 MHz this means the register is guaranteed cleared within 200 ns, eliminating the need for an asynchronous reset and avoiding glitch-induced false output states during power-up or fault recovery sequences.
For a student or prototyping environment, why is the DIP-16 package of the CD74HC195EG4 still preferred over surface-mount alternatives?
The 2.54 mm pitch DIP-16 package fits standard breadboards and zero-force IC sockets, enabling insertion and removal without soldering. For classroom lab setups or rapid proof-of-concept builds this cuts assembly time to under 1 minute per IC versus the 5–10 minutes needed to hand-solder a 0.65 mm TSSOP-16, while the 0.6-inch body width leaves probe space between pins for oscilloscope measurements.
When would a designer choose CD74HC195EG4 over a larger 8-bit shift register in a serialization application?
For a 4-bit status word or nibble-wide parallel bus running at up to 25 MHz, the CD74HC195EG4 requires only one IC versus cascading two 4-bit stages from an 8-bit device. This halves propagation delay accumulation (typically 7 ns per stage at 5 V) and simplifies timing analysis, making it the economical choice when the data path is inherently 4 bits wide.
