RD74LVC1G79
Single Positive Edge-triggered D-type Flip Flop
REJ03D0695–0100
Rev.1.00
Feb 23, 2006
Description
The RD74LVC1G79 has D-type flip flop in a 5-pin package. The input data is transferred to the output at the rising
edge of clock pulse CLK. 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)
±32 mA (@V
CC
= 4.5 V)

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