74HC390D规格书详情
1. General description
The 74HC390; 74HCT390 is a dual 4-bit decade ripple counter divided into four separately clocked
sections. The counters have two divide-by-2 sections and two divide-by-5 sections. These sections
share an asynchronous master reset input (nMR) and can be used in a BCD decade or bi-quinary
configuration. If master reset inputs (1MR and 2MR) are used to simultaneously clear all 8 bits of
the counter, a number of counting configurations are possible within one package. The separate
clocks (nCP0 and nCP1) of each section allow ripple counter or frequency division applications of
divide-by-2, 4, 5, 10, 20, 25, 50 or 100. Each section is triggered by the HIGH-to-LOW transition
of the clock inputs (nCP0 and nCP1). For BCD decade operation, the nQ0 output is connected
to the nCP1 input of the divide-by-5 section. For bi-quinary decade operation, the nQ3 output is
connected to the nCP0 input and nQ0 becomes the decade output. A HIGH on the nMR input
overrides the clocks and sets the four outputs LOW. This device features reduced input threshold
levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use
of current limiting resistors to interface inputs to voltages in excess of VCC.
