Description
- Микросхемы SNx4HC74 содержат два независимых D-триггера, срабатывающих по положительному фронту. Низкий уровень на входах предустановки (PRE) или сброса (CLR) устанавливает или сбрасывает выходы независимо от уровней на других входах. Когда PRE и CLR неактивны (высокий уровень), данные на входе данных (D), удовлетворяющие требованиям времени установки, передаются на выходы по положительному фронту тактового импульса (CLK). Запуск тактового сигнала происходит при определенном уровне напряжения и не связан напрямую со временем нарастания CLK. По истечении интервала времени удержания данные на входе D можно изменять, не влияя на уровни на выходах.
- Широкий диапазон рабочего напряжения: от 2 В до 6 В
- Выходы могут управлять нагрузкой, соответствующей до 10 входам LSTTL
- Низкое энергопотребление: максимальный ток ICC 40 мкА
- Типичное значение tpd = 15 нс
- Выходной ток ±4 мА при 5 В
- Очень низкий входной ток: 1 мкА
