74HC164

The 74HC164; 74HCT164 is an 8-bit serial-in/parallel-out shift register. The device features two serial data inputs (DSA and DSB), eight parallel data outputs (Q0 to Q7). Data is entered serially through DSA or DSB and either input can be used as an active HIGH enable for data entry through the other input. Data is shifted on the LOW-to-HIGH transitions of the clock (CP) input. A LOW on the master reset input (MR) clears the register and forces all outputs LOW, independently of other inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

A Simple Clock

“In this coronavirus lockdown, I came back to my hometown. Everything is perfectly fine here but there was one small problem. There is no clock on my table. I know a table clock sounds a little redundant especially in this …

ATtiny13-Based, Key-Controlled Simple Dimmer

“A tiny dimmer with corrected output for resistive loads. Controlled with 3 keys and showing current value on 8 tiny colored LEDs. Based on this project, I made a general purpose dimmer for incandescent bulbs or soldering irons with these …

TTL/CMOS Linear LED Clock

“A TTL/CMOS based clock that displays the time along a 60 LED bargraph. I like clocks. I like LEDs. I like mucking around with circuits. I want to make a clock that displays the time along an LED bargraph …

Pseudo random number generator
