Al que me pueda ayudar se lo agradecere Me he cansado de buscar por Internet alguna forma de realizar una memoria rom con Flip-flops y me gustaria saber si alguien tiene idea de como se hace, es para un proyecto de mi escuela. 0 13 mA VCC = MAX Note 1: Not more than one output should be shorted at a time, nor for more than 1 second. 1pF up to 900nF. Celles-ci sont contenues dans le circuit intégré 74LS74 inséré sur le support ICX. Integrated circuit flip flop dual D with set & reset 14-DIP used on many pinball machine circuit boards. They offer active LOW, high sink current outputs for driving indicators directly. 74LS74 - Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear, and Complementary Outputs "A circuit the produces a digital output signal that is half the. An integrated circuit or monolithic 74ls4 circuit also referred to as an ic, a chip, or a microchip is a set of electronic circuits on one small plate chip of semiconductor material, normally silicon. 6 V) ESD protection: HBM JESD22-A114F exceeds 2000 V. The same goes with IC5, pins 13, 14, 15 and R5 (signals: R/W and Φ1). Save more when you buy in bulk.
