SN74LVTH16244ADGVR

3.3 -V ABT 16位缓冲器/驱动器，具有三态输出 3.3-V ABT 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

DESCRIPON/ORDERING INFORMATION

The "LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable OE inputs.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
