This device divides the incoming clock frequency by a number (a power of 2) that is preset by the Programming inputs.

It has two Clock inputs, either of which may be used as a clock inhibit.

The device also has an active-low Reset, which initializes the internal flip-flop states.

High Speed Operation: tpd (Clock to Q) = 16 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 CLR L H H H H L H X X H CLK1 X CLK2 X L Q Output Mode Cleared to L Count Count Inhibit Inhibit HD74HC292/HD74HC294 HD74HC292 Programming Inputs Frequency Division Q Out TP1 TP2 TP3 Binary D.
