4-STAGE PRESETTABLE RIPPLE COUNTERS
The SN54/74LS196 decade counter is partitioned into divide-by-two and divide-by-five sections which can be combined to count either in BCD (8, 4, 2, 1) sequence or in a bi-quinary mode producing a 50 duty cycle output. The SN54/74LS197 contains divide-by-two and divide-by-eight sections which can be combined to form a modulo-16 binary counter. Low Power Schottky technology is used to achieve typical count rates of 70 MHz and power dissipation of only 80 mW.
• Low Power Consumption — Typically 80 mW
• High Counting Rates — Typically 70 MHz
• Choice of Counting Modes — BCD, Bi-Quinary, Binary
• Asynchronous Presettable
• Asynchronous Master Reset
• Easy Multistage Cascading
• Input Clamp Diodes Limit High Speed Termination Effects
