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 +85C All inputs: VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs: VO (Max.) = 5.5 V (@VCC = 0 V) Output current: 4 mA (@VCC = 1.65 V) 8 mA (@VCC = 2.3 V) 24 mA (@VCC = 3.0 V) 32 mA (@VCC = 4.5 V) * Ordering Information

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.
