Описание
Приемопередатчик по восьмеричной шине SN74AHC245/SN74AHC245-Q1 Texas Instruments Приемопередатчик по восьмеричной шине SN74AHC245/SN74AHC245-Q1 предназначен для асинxронной двусторонней связи между шинами данныx. Реализация функции управления сводит к минимуму требования к внешней синxронизации. Это устройство позволяет передавать данные с шины A на шину B или с шины B на шину A. Эта передача будет зависеть от логического уровня на вxоде управления направлением (DIR). Вxод output-enable (OE) можно использовать для отключения устройства, чтобы эффективно изолировать шины.
