3 Description
SN74LV4T125 is a low-voltage CMOS buffer gate
that operates at a wider voltage range for portable,
telecom, industrial, and automotive applications. The
output level is referenced to the supply voltage and is
able to support 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS
levels.
The input is designed with a lower threshold circuit to
match 1.8-V input logic at V_CC = 3.3 V and can be
used in 1.8 V to 3.3 V level-up translation. In addition,
the 5-V tolerant input pins enable down translation
(for example, 3.3 V to 2.5 V output at V_CC = 2.5 V).
The wide V_CC range of 1.8 V to 5.5 V allows the
generation of desired output levels to connect to
controllers or processors.
The SN74LV4T125 device is designed with current-
drive capability of 8 mA to reduce line reflections,
overshoot, and undershoot caused by high-drive
outputs.
