Логическая ИС SN74LVTH541DW

Буфер / драйвер , неинвертирующий, 3 состояния, 2.7В до 3.6В, SOIC-20

The SN74LVTH541DW is an octal Buffer/Driver designed specifically for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It is ideal for driving bus lines or buffer memory address registers. This device features inputs and outputs that facilitate printed circuit board layout. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1\ or OE2\) input is high, all outputs are in the high-impedance state. Active bus-hold circuitry holds unused or un-driven inputs at a valid logic state. Use of pull-up/pull-down resistors with the bus-hold circuitry is not recommended. When VCC is between 0 and 1.5V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5V, OE\ 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.

• IOFF and power-up 3-state support hot insertion
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Support unregulated battery operation down to 2.7V
• Latch-up performance exceeds 500mA per JESD 17
• <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
• Green product and no Sb/Br
