3 Description

The SN54SC8T244-SEP is an octal buffer with 3-state outputs. The device is configured into two banks of four drivers, each controlled by an output enable pin.

The input is designed with a reduced threshold circuit to support up translation when the supply voltage is larger than the input voltage. Additionally, the 5V tolerant input pins enable down translation when the input voltage is larger than the supply voltage. The output level is always referenced to the supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.
