Quad S-R Latch
The 74LS279 is a 16-pin dual 4-bit binary ripple counter with separate clocks and reset inputs. It is a low power, high speed, low-power Schottky TTL (LSTTL) logic device. Description: The 74LS279 is a dual 4-bit binary ripple counter with separate clocks and reset inputs. It is a low power, high speed, low-power Schottky TTL (LSTTL) logic device. It has two independent 4-bit binary ripple counters with separate clocks and reset inputs. The counters are synchronous and can be used to count up or down. The outputs of the counters are available on the Q0 to Q3 pins. The counters can be reset to zero or to any other count by applying a low level to the reset input. Features: Low power Schottky TTL (LSTTL) logic Two independent 4-bit binary ripple counters Separate clocks and reset inputs Synchronous operation Count up or down Outputs available on Q0 to Q3 pins Reset to zero or any other count Applications: The 74LS279 can be used in a variety of applications such as frequency division, pulse generation, and time delay circuits. It can also be used in digital clocks, timers, and counters. (For reference only)
