You can use a single stage and add another 8-bit register like 74S, after the shift register to mimic the 2nd stage of the HC if the flicker will be a problem, or if you have several devices that that you want to share the data and clock line across such as if using SPI to send data out.

All products are sold subject to the terms and conditions of sale supplied at the time of order acknowledgement, including those pertaining to warranty, patent infringement, and limitation of liability. Testing and other quality control techniques are utilized to the extent Tl deems necessary to support this warranty.
Voltage vaiues are with re;paci to nerwork ground terminal. If driving LEDs, this may be seen as flicker as the dqtasheet are loaded in using the shiftout command.
As this project was sort of sponsored by the school, I get to draw parts from the component store. Tl warrants performance of its semiconductor products to the specifications applicable at the time of dwtasheet in accordance with Tl’s standard warranty. Hi I’m building a 24×6 led matrix display that uses some 74HC s.

Questions concerning potential risk applications should be directed to Tl through a local SC sales office, In order to minimize risks associated with the customer’s applications, adequate design and operating safeguards should be provided by the customer to minimize inherent or procedural hazards.
S V applied to the J, K, and data inputs, dataxheet ic mfias ured by applying a momentary ground, followed by 4.

Serial data for this mode is entered at the J-K inputs. Now with Unlimited Eagle board sizes! However there were other 8bit shift registers and I’m not sure 7ls195a those will work perfectly with the arduino uno. Voltage values ara 74ls195s respect to network ground terminal. However, they didn’t have 74HC s. A single stage serial to parallel shift register will also work, the outputs will change tho as the data is shifted in.
S V, to clock.
The register has two modes of operation: I’m pretty new to shift registers. The clock pulse generator has dataaheet following characteristics: When tasting 1 maxvary tha clock PRFH. Fatasheet warrants performance of its semiconductor products and related software to the specifications applicable at the time of sale in accordance with Tl’s standard warranty. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements.

The data is loaded into the associated flip-flop and appears at the outputs after the positive transition of the clock input.
Use of Tl products in such applications requires the written approval of an appropriate Tl officer. These inputs permit the first stage to perform as a J-K, D- or T-type flip-flop as shown in the function table. The high-performance ‘S1 95, with a 1 megahertz typical maximum shift-frequency, is particularly attrac- tive for very-high-speed data processing systems.
You serial shift in 8 bits into stage 1, then use a 2nd clock to move the data in parallel into stage 2. In order to minimize risks associated with the customer’s applications, adequate design and operating safeguards must be provided by the customer to minimize inherent or procedural hazards.
Products conform to J!

All inputs are buffered to lower the input drive requirements. K, and data inputs, is measured by applying a momentary ground, followed by 4. A clear pulse is applied prior to aach test. Check their datasheets at www.
