HD74ALVC2G74 Single D-type Flip Flops with Preset and Clear REJ03D0169–0300Z (Previous ADE-205-639B (Z)) Rev.3.00 Dec.18.2003 Description The HD74ALVC2G74 has independent data, preset, clear, and clock inputs Q and Q outputs in an 8 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. • Supplied on emboss taping for high-speed automatic mounting. • Supply voltage range : 1.2 to 3.6 V Operating temperature range: -40 to +85°C • All inputs VIH (Max.) = 3.6 V (@VCC = 0 V to 3.6 V) A
