Texas Instruments (SN74LS193N) Binary Synchronous Up / Down Counter, 32 MHz

Binary Synchronous Up / Down Counter, 32 MHz, 4.75 V to 5.25 V, DIP-16 Product Overview The SN74LS193N is a synchronous 4-bit up/down Binary Counter with dual clock and clear. This monolithic circuit is synchronous reversible counter having a complexity of 55 equivalent gates. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincidently with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous counter. The outputs of the four flip-flops are triggered by a low-to-high-level transition of either count input. The direction of counting is determined by which count input is pulsed while the other count input is high. A clear input has been provided which forces all outputs to the low level when a high level is applied. The clear function is independent of the count and load inputs. The clear, count and load inputs are buffered to lower the drive requirements. Cascading circuitry provided internally Individual preset to each flip-flop Fully independent clear input Pb-free product Product Information Logic Family / Base Number: 74LS193 Counter Type: Binary, Synchronous, Up / Down Clock Frequency: 32MHz Count Maximum: 16 Logic Case Style: DIP No. of Pins: 16Pins Supply Voltage Min: 4.75V Supply Voltage Max: 5.25V Logic IC Family: 74LS Logic IC Base Number: 74193 Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - MSL: -
