Each section can be used separately or tied together (Q to CP) to form BCD, bi-quinary, modulo-12, or modulo-16 counters. All of the counters have a 2-input gated Master Reset (Clear), and the LS90 also has a 2-input gated Master Set (Preset 9).\u003c\/span\u003e\u003c\/p\u003e\r\n\r\n\u003ch2\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e:\u003c\/h2\u003e\r\n\r\n\u003col\u003e\r\n\t\u003cli\u003eLow Power Consumption ...Typically 45 mW\u003c\/li\u003e\r\n\t\u003cli\u003eHigh Count Rates ...Typically 42 MHz\u003c\/li\u003e\r\n\t\u003cli\u003eChoice of Counting Modes . . .
