SN74AHCT244DW

Буфер / драйвер линии, неинвертирующий, 3 состояния, 4.5В до 5.5В, SOIC-20.

The SN74AHCT244DW is an octal Buffer/Driver designed specifically to improve both the performance and density of 3-state memory-address drivers, clock drivers and bus-oriented receivers and transmitters. The SNx4AHCT244 device is organized as two 4-bit buffer/line driver with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, 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.
