74HC273

The 74HC273; 74HCT273 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MR forces the outputs LOW independently of clock and data inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Stacks - A16-Bit Breadboard Processor

“Project to simulate, design, and build a 16-bit breadboard computer. The breadboards are installed in a 3-layer plastic enclosure for circuit stabilization and protection. I designed my own hardware architecture and instruction set architecture (ISA) loosely based on RISC-V …

Homemade Successive Approximation Register ADC

“This is a homemade 7-bit SAR ADC using discrete components for principle study. The following is an introduction to a Successive Approximation Register Analog to Digital Converter (SAR ADC) that I made myself for principle study, and observing the conversion …

MK1 8bit Computer

“The MK1 CPU is composed of several modules, all connected trough a common 8-bit BUS, the status of each module is shown by dedicated LEDs. The clock module is designed to allow step-by-step execution; in automatic mode the clock speed …

1 Square Inch TTL CPU

“A microprocessor built with TTL chips. In one square inch. What would be cool for the square inch contest or Hackaday prize…. How about a homebrew CPU with TTL chips ? This is the smallest TTL Homebrew CPU in the world …
