The set 4N35, 4N36, 4N37 are popular and versatile optocouplers for isolation of circuit blocks. The most important feature is the Isolation test voltage 5000 VRMS that means 5KV. But PCB Design is very important to get this isolation for your products too.
The site started in 1995 under the name of Interfacing the PC and was moved to beyondlogic.org on the 29th February 2000 where it has cemented itself as an established, up to date source of non-biased information.
Beyond Logic - Interfacing the PC Beyond Logic includes detailed information on Universal Serial Bus, Serial Ports (RS232), Parallel Ports (SPP/ECP/EPP/IEEE1284), Device Drivers and more.
The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V. LM3914 - Versatile and Easy use Display
From Signals, Filters, Sampling, Aliasing to Data Converters. This book covers the fundamentals of Mixed-CMOS Design. This book will fill a hole in the technical literature for an advanced-tutorial book on mixed-signal circuit design. There are no competitors in this area. Mixed-signal design is performed in industry by a select few gurus .
These are high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
An Excellent way to expand your A/D convertors I/O capability. Multiple Analog Inputs can be routed to a single Opamp or Analog Input of a uC or uP System. Use protection Zeners or clamping inputs.
Providing detailed electronic design information regarding Interface, Computer, Cable, Processor and Embedded Buses. - Leroy Davis Buses used on Personal Computers, Computers & Peripherals, Standards, Wireless, Logic Design.

The site is geared toward Engineers who develop or design equipment. There are 3 main sections; OEM Equipment / Components listings, Computer buses, and engineering design data.
74HCT373 - High Speed CMOS Logic Octal Transparent Latches with 3-State Outputs. The 'HCT373 devices are octal transparent D-type latches. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched at the logic levels of the D inputs.
What it can do ? - This is like a Byte of Memory, A Byte means 8 Bits. A Bit Means one Input or Output Pin of an IC, Which understands Logic 1 is High and Logic 0 is Low.
