Логическая ИС SN74LV245ADW

Приемопередатчик , неинвертирующий, 3 состояния, 2В до 5.5В, SOIC-20

The SN74LV245ADW is an octal Bus Transceiver with 3-state outputs and is designed for 2 to 5.5V VCC operation. It is also e designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control input. The output-enable input can be used to disable the device so the buses are effectively isolated. To ensure the high-impedance state during power up or power down, output enable should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

• Support mixed-mode voltage operation on all ports
• IOFF Supports partial-power-down mode operation
• Latch-up performance exceeds 250mA per JESD 17
• 6.5ns at 5V Propagation delay (tpd)
• <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
• >2.3V at VCC = 3.3V, TA = 25°C VOHV (output VOH undershoot)
• Green product and no Sb/Br
