SN74LVT244B Datasheet (Texas Instruments) - 3.3-V ABT OCTAL BUFFER/DRIVER

SN74LVT244B, 3.3-V ABT OCTAL BUFFER/DRIVER

ordering information This octal buffer and line driver is 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 SN74LVT244B is organized as two 4-bit line drivers with separate output-enable (OE) inputs.
