RD74LVC1G125
Bus Buffer with 3–state Output
REJ03D0731–0100
Rev.1.00
Apr 13, 2006
Description
The RD74LVC1G125 has bus buffer with 3–state output in a 5-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

Test Conditions
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
ngs
observed.
2. This value is limited to 5.5 V maximum.
