SN74AHCT244-Q1 具有三态输出的汽车类八路缓冲器/驱动器

SN74AHCT244-Q1 描述

This octal buffer/driver is designed specifically to improve both the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters.

The SN74AHCT244 is organized as two 4-bit buffers/line drivers 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 shall be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver
