HD74LV2G125A
Dual Bus Buffer with 3state Output
REJ03D00990500Z
(Previous ADE-205-347D (Z))
Rev.5.00

Description
The HD74LV2G125A has dual bus buffer with 3state output in a 8 pin package. Output is disabled when
the associated output enable (
OE) input is high. To ensure the high impedance state during power up or
power down,
OE should be connected to V
CC
through a pull-down resistor; the minimum value of the
resistor is determined by the current souring capability of the driver. 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
The basic gate function is lined up as Renesas uni logic series.
Supplied on emboss taping for high-speed automatic mounting.

Notes:
The absolute maximum ratings are values, which must not individually be exceeded, and
furthermore no two 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 observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150C.
