Texas Instruments (SN74HC161N) Binary Counter, 44 MHz

Binary Counter, 44 MHz, 2 V to 6 V, DIP-16Product OverviewThe SN74HC161N is a 4-bit presettable Synchronous Binary Counter features aninternal carry look-ahead for application in high-speed counting designs.Synchronous operation is provided by having all flip-flops clockedsimultaneously so that the outputs change coincident with each other when soinstructed by the count-enable (ENP, ENT) inputs and internal gating. This modeof operation eliminates the output counting spikes that are normally associatedwith synchronous (ripple-clock) counters. A buffered clock input triggers thefour flip-flops on the rising (positive-going) edge of the clock waveform. It isfully programmable, that is, it can be preset to any number between 0 and 9 or15. As presetting is synchronous, setting up a low level at the load inputdisables the counter and causes the outputs to agree with the setup data afterthe next clock pulse, regardless of the levels of the enable inputs.Outputs can drive up to 10 LSTTL loadsInternal look-ahead for fast countingCarry output for n-bit cascadingSynchronous countingSynchronously programmable80µA Maximum low power consumption14ns Typical tpd±4mA Output drive at 5V1µA Maximum low input currentApplicationsIndustrialProduct InformationLogic Family / Base Number: 74HC161Counter Type: BinaryClock Frequency: 44MHzCount Maximum: 15Logic Case Style: DIPNo. of Pins: 16PinsSupply Voltage Min: 2VSupply Voltage Max: 6VLogic IC Family: 74HCLogic IC Base Number: 74161Operating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -MSL: -
