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: 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 Part Name RD74LVC1G79WPE Package Type Package Code (Previous Code) Package Abbreviation WCSP-5 pin SXBG0005LB–A WP (TBS-5CV) Article Indication Marking Year code Month code EFYM Rev.1.00 Feb 23, 2006 page 1 of 6 Taping Abbreviation (Quantity) E (3,000 pcs/reel) RD74LVC1G79 Function Table Inputs CLK D Output Q ↑ H H ↑ L L L X Q0 H: High level L: Low level X: Immaterial ↑: Low to high transition Q0 : Level of Q before the indicated steady input conditions was established.
