SN74LS290D規(guī)格書詳情
DECADE COUNTER; 4-BIT BINARY COUNTER
The SN54 /74LS290 and SN54 /74LS293 are high-speed 4-bit ripple type counters partitioned into two sections. Each counter has a divide-by-two section and either a divide-by-five (LS290) or divide-by-eight (LS293) section which are triggered by a HIGH-to-LOW transition on the clock inputs. Each section can be used separately or tied together (Q to CP)to form BCD, Bi-quinary, or Modulo-16 counters. Both of the counters have a 2-input gated Master Reset (Clear), and the LS290 also has a 2-input gated Master Set (Preset 9).
? Corner Power Pin Versions of the LS90 and LS93
? Low Power Consumption . . . Typically 45 mW
? High Count Rates . . . Typically 42 MHz
? Choice of Counting Modes . . . BCD, Bi-Quinary, Binary
? Input Clamp Diodes Limit High Speed Termination Effects
