Hardware Design Considerations for a Wireless LED based Display Design
PDF, 682 Kb, Datei veröffentlicht: Jun 11, 2014
Scoreboards have different purposes with various features. Scoreboards are typically used for displaying scores of a game played between two teams. These games can be a timed or an untimed event. The application described in this application report creates a multi-sport scoreboard that is cost efficient, portable, and easy to use. The display values on the scoreboard are transmitted wirelessly.

Designing with the SN54/74LS123 (Rev. A)
PDF, 118 Kb, Revision: A, Datei veröffentlicht: Mar 1, 1997
The Texas Instruments (TI) SN54/74LS123 dual retriggerable monostable multivibrator is a one-shot device capable of verylong output pulses and up to 100% duty cycle. The ?LS123 also features dc triggering from gated low-level active A andhigh-level active B inputs and provides a clear input that terminates the output pulse of any predetermined time independentof timing components R ext and
