Additional preview pages of the HD74HC273 datasheet.

This device contains 8 master-slave flip-flops with a common clock and common clear.

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.

High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Inputs Clear L H H H H L Clock X D X H L X X Outputs Q L H L No change No change HD74HC273 Pin Arrangement Clear 1Q 1D 2D 2Q 3Q 3D 4D 4Q 1 2 3 4 5 6 7 8 9 20 VCC Q Q 19 8Q 18 8D 17 7D 16.
