ReviewsTemperature Compensated Crystal Oscillator

Glarks 40Pcs 74LSxxx and 74HCxxx Series Low-Power Logic IC Assortment Kit

...h for 20pcs. They are placed in a transparent plastic box, easy to transport and storage..
♛ [Small Component]: Our IC chips are small electronic components, small in size, they only take up very little space in the application. And the power consumption is low, can work normally with little consumption..
♛ [High Temperature Resistance]: The IC chips have good high temperature performance and can work normally between -40 to 85 Celsius (-40 to 185 degree). So you don't have to worry about the high temperature after connecting them to the peripheral circuit, or burning out the it after long time use..
♛ [Long Life Service]: ICs are made of high-quality materials, they are very durable, can serve you for a long time. And the safety and reliability are high, so you don't have to worry even if you work for a long time..
♛ [Widely Application]: 74LSxxx and 74HCxxx Series ICs can be used as Bistability, register, shift register, oscillator, oscillator, divider counter, etc..

New material, new design Among the new features of Oscar II is to the extensive use of stainless steel that immediately shows strength and solidity, as well as enhancing the machine..
Compact At only 30 cm, Oscar is able to work in both a home and office setting..
Perfect extractions The brewing unit is temperature compensated giving consistent and quality extractions..
Professional Oscar enables the production of espressos or cappuccinos just like in a café. The thermo-compensated group and steaming system are derived from larger, professional machines..
