3 Description
The SN74LV8T244-EP is an octal buffer with 3-
state outputs and Schmitt-trigger inputs. 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.
