SN54LVTH244A 具有三态输出的 3.3V ABT 八路缓冲器/驱动器

SN54LVTH244A 描述

These octal buffers and line drivers are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The ’LVTH244A devices are organized as two 4-bit line drivers with separate output-enable (OE)\ inputs. When OE\ is low, the devices pass 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 pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level
