74LVC245APW 8 Bit Çevirici
Octal Bus Schmitt Trigger Transceiver 3 State DC 3.3V 5V 20TSSOP
Bu entegre devre, çift yönlü veri iletimi sağlamak için tasarlanmış bir 8-bit 3-state ( üç durumlu ) veri hattı transceiver’ıdır. Genellikle mikrokontrolcülerin veya diğer dijital devrelerin veri yollarını birbirine bağlamak ve yönlendirmek amacıyla kullanılır.
The 74LVC245A; 74LVCH245A is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
