The SN74LV273ANSR represents a logic device in the Flip Flops category. The SN74LV273ANSR is an octal Flip Flop device. This device has eight D-type edge-triggered latches with 3-State outputs that are designed for low voltage applications. The logic is designed to operate from a single supply voltage of 3.3V and has been tested with outputs at 2.5V. In this article and will explore its application field, as well as its working principle.ApplicationsThe SN74LV273ANSR is suitable for a range of applications such as logic loading, parallel data communication, data transfer and synchronous address decoding. It is used for applications such as memory address decoding, synchronous address decoding, logic loading, parallel data communication, data transfer, data buffering and shift registers.Working PrincipleThe SN74LV273ANSR is a 8-bit edge triggered latch with active-low Set and Reset input pins. When pins Set and Reset are both at a high voltage, the latch acts as a transparent latch. When either of the Set or Reset pins is first taken to a low voltage the latch will be forced to either a HIGH or LOW logic level output depending on which input is low. If the Set pin is taken low, then the latch will output a high level. Likewise if the Reset is taken low, then the latch will output a low level.The SN74LV273ANSR also has an enable pin that can be used to activate the latch. When the enable pin is high, the device will latch the data into each latch stage. When the enable pin is low, the latch will function as a 3-State output device and no data will be latched. The 3-State output pins can be used to turn off the output devices connected to them.The SN74LV273ANSR also contains flip-flop clocking capability that allows it to be used to clock internal or external devices. It can be clocked with either the complimentary clock (CLK) barred inputs or the single sided clock (CLK) barred inputs. The CLK bar pins are active low, meaning that when the CLK bar is high, the clock signal will be set and when the CLK bar is low, the clock signal will be cleared.The SN74LV273ANSR has also been designed for compatibility with low voltage product families. The device is designed to operate at a single supply voltage of 3.3V and has been tested with outputs at 2.5V. The device is TTL compatible, meaning that it will operate from a single voltage source ranging from 4.5 to 5.25V.ConclusionIn conclusion, the SN74LV273ANSR is a versatile 8-bit edge triggered latch with active-low Set and Reset input pins and 3-State output. It is suitable for a range of applications including logic loading, parallel data communication, data transfer and synchronous address decoding. The device is TTL compatible, meaning that it will operate from a single supply voltage of 3.3V and has been tested with outputs at 2.5V. The SN74LV273ANSR also contains Flip Flop clocking capability that allows it to be used to clock internal or external devices.
