SN54/74LS90 SN54/74LS92 DECADE COUNTER; SN54/74LS93 DIVIDE-BY-TWELVE COUNTER; 4-BIT BINARY COUNTER DECADE COUNTER; The SN54 / 74LS90, SN54 / 74LS92 and SN54 / 74LS93 are high-speed 4-bit ripple type counters partitioned into two sections. Each counter has a di- DIVIDE-BY-TWELVE COUNTER; vide-by-two section and either a divide-by-five (LS90), divide-by-six (LS92) or 4-BIT BINARY COUNTER divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transi- LOW POWER SCHOTTKY tion on the clock inputs. 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). · Low Power Consumption . . .

Sept. 1995 Edition 3.0a DATA SHEET MB506 ULTRA HIGH FREQUENCY PRESCALER ULTRA HIGH FREQUENCY PRESCALER The Fujitsu MB506 is a high frequency, up to 2.4GHz, prescaler used with a frequency synthesizer to form a Phase Locked Loop (PLL). It will divide the input frequency by the modulus of 128 or 256 and the output level is 1.6V peak to peak on ECL level.Operation in the 1.6GHz range meets the specification for applications in Direct Broadcasting Satellite Systems (DBS), CATV systems, and UHF Transceivers.
