NTE Electronics, Inc. Integrated Circuits (ICs) - Logic - Counters, Dividers NTE74LS192

The NTE74LS192 is a synchronous 4-bit up/down counter designed for TTL applications, packaged in a 16-lead plastic DIP format. It features synchronous operation, allowing all flip-flops to be clocked simultaneously, which minimizes output counting spikes typically found in asynchronous counters. The counter can be programmed to preset each output independently, enabling it to function as a modulo-N divider by adjusting the count length through preset inputs. This device includes a clear input that resets all outputs to a low state, independent of the counting and loading processes. It is designed for cascading without requiring external circuitry, with both borrow and carry outputs available for connecting multiple counters. The maximum clock frequency is 25 MHz, and it operates within a temperature range of 0¬8C to +70¬8C. The NTE74LS192 is suitable for applications requiring reliable counting and division functions in digital circuits.
