RD74VT1G126
Bus Buffer Gate with 3-state Output /
Dual Supply Voltage Translator
REJ03D0517–0100
Rev.1.00
Jun. 01, 2005
Description
The RD74VT1G126 has a bus buffer gate with 3-state output in a 6 pin package. Output is disabled when the
associated output enable (OE) input is low. To ensure the high impedance state during power up or power down, OE
should be connected to GND through a pull-down resistor; the minimum value of the resistor is determined by the
current sourcing capability of the driver. The input is designed to track V
CC
IN, which accepts voltages from 1.2V to
3.6V, and the output is designed to track V
CC
OUT, which operates at 1.2V to 3.6V. Low voltage and high-speed
operation is suitable for the battery powered products (e.g., notebook computers), and the low power consumption
extends the battery life.
Features
•
This product function as level shift that change V

•
The basic gate function is lined up as Renesas uni logic series.
•
Supplied on emboss taping for high-speed automatic mounting.

The absolute maximum ratings are values, which must not individually be exceeded, and furthermore, no two
st
of which may be realized at the same time.
1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are
ngs
observed.
2. This value is limited to 4.6 V maximum.
