The TC74LCX07FK(EL,K) is a high-speed CMOS, quadruple bus buffer (non-inverting) gate, which belongs to the group of Logic - Buffers, Drivers, Receivers, Transceivers. It is designed for 2-V to 5.5-V VCC operation, and it is fabricated using a silicon gate CMOS technology. The device features low power consumption, low noise, wide operating temperature range and good common mode characteristics.

The TC74LCX07FK(EL,K) consists of four independent buffer gates with three-state outputs. The output enable (OE) input controls the output buffer’s on/off state. When OE is low, the outputs remain in a high impedance state, and when OE is high, the outputs assume the levels indicated by the data (D) inputs. The device has two separate power inputs: VCC and VCCA. The VCC pin is the power supply for the logic, while the VCCA pin is the power supply for the output buffer.

The TC74LCX07FK(EL,K) can be used in a variety of applications, such as fanout buffer, data repeater, and transmission gate. In fanout buffer applications, the device is used to drive 4 low-power devices from a single higher-power output. In data repeater applications, the device is used to drive signals over long traces or via external tracks on a printed circuit board (PCB). In transmission gate applications, the device is used to steer data bits on/off the bus in response to control signals.

The operating principles of the TC74LCX07FK(EL,K) are based on the principles of field-effect transistors (FETs). It contains four CMOS inverters, each of which is composed of a p-channel FET and an n-channel FET. When a logic high level is applied to the input signal, the p-channel FET is activated while the n-channel FET is turned off. This causes a logic high level to present on the output signal. Conversely, when a logic low level is applied to the input signal, the n-channel FET is activated while the p-channel FET is turned off. This causes a logic low level to present on the output signal.

The TC74LCX07FK(EL,K)\'s output enables (OE) control the output buffers\' states. When OE is high, the output buffers are enabled, allowing the output signals to assume the levels indicated by the data (D) inputs. When OE is low, the outputs remain in a high impedance state, keeping the output signals unaffected.

In summary, the TC74LCX07FK(EL,K) is a high-speed CMOS, quad buffered logic gate with three-state outputs. It is well-suited for fanout buffer, data repeater and transmission gate applications, and its operation is based on the principles of FETs. Moreover, the device features low power consumption, low noise, wide operating temperature range and good common mode characteristics.
