HD74LV273A octal d-type flip-flops with clear ade-205-273 (z) 1st edition april 1999 description the HD74LV273A has eight edge trigger d-type flip-flops with clear in a 20-pin package. data on the d input having the specified setup and hold times is transferred to the q output on the low to high transition of the clock input. the clear input when low, sets all outputs to a low state. low-voltage and high-speed operation is suitable for battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life. features v cc = 2.0 v to 5.5 v operation 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) typical v ol ground bounce < 0.8 v (@v cc = 3.3 v, ta = 25 c) typical v oh undershoot > 2.3 v (@v cc = 3.3 v, ta = 25 c) output current 6 ma (@v cc = 3.0 v to 3.6 v), 16 ma (@v cc = 4.5 v to 5.5 v) function table inputs clr clk d output q l xxl h - hh h - ll h xq 0 note: h: high level l: low level x: immaterial - : low to high transition : high to low transition q 0 : output level before the indicated steady state input conditions were established.
