RD74LVC2G125
Dual Bus Buffer with 3–state Output
REJ03D0753–0100
Rev.1.00
Jul 26, 2006
Description
The RD74LVC2G125 has dual bus buffer with 3–state output in an 8-pin package. 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.
Supply voltage range: 1.65 to 5.5 V
Operating temperature range: –40 to +85°C
All inputs: V
IH
(Max.) = 5.5 V (@V
CC
= 0 V to 5.5 V)
All outputs: V
O
(Max.) = 5.5 V (@V
CC
= 0 V)
Output current:
±4 mA (@V
CC
= 1.65 V)
±8 mA (@V
CC
= 2.3 V)
±24 mA (@V
CC
= 3.0 V)

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.
