Semiconductors

Diode - Zener, 1W, 5% Tolerance
A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.

Integrated Circuit - SN74LS175, Quadruple D-Type Flip-Flops, 16-pin DIP
This quad flip flop is a part used in our Relay True Bypass Switching Part 2: Momentary and Soft Touch Switches article. To read the full article and learn about a circuit for relay switching in stomp box effects, please see the following link. https://www.amplifiedparts.com/tech-articles/relay-true-bypass-switching-2 These monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All have a direct clear input, and the '175, 'LS175, and 'S175 feature complementary outputs from each flip-flop. Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse.
