The 74F646SPC is an advanced output low voltage CMOS device that belongs to the family of logic buffers, drivers, receivers and transceivers. It is a 1-to-8 buffer/driver that features three selectable levels of output current for bus driving capability. The device can be used for wide variety of applications, such as line drivers, D/A converters and peripheral interfaces.

The 74F646SPC integrates five gate inputs and one enable input, which allow higher system performance and greater design flexibility. The device is suitable for multipoint applications, where low power dissipation is paramount. It allows multiple loads to be interfaced without the need for external level shifting circuits, which simplifies the design process.

The 74F646SPC features three selectable levels of output current for bus driving capability. The logic inputs are TTL-compatible, allowing for both logic-high and logic-low inputs. The device also features an internal power-on reset (POR) circuit, which ensures that the output is always in the high-impedance state when power is first applied. The device operates over a wide temperature range and has an integrated thermal shutdown circuitry to protect against device damage due to thermal overloads.

The 74F646SPC is composed of five stages, including two clocks and three latches. The two clocks are used to alternately latch the input data onto two sets of three outputs each. The device is configured so that it can be operated in the low voltage CMOS and TTL logic level, allowing for a more cost-effective solution. The device also features an internal reset circuit, which ensures that the QS (Quasi Shift) register is always in the low-impedance state when power is first applied.

The 74F646SPC works by utilizing the three-stage CMOS design. This allows for a greater fan-out capability and greater system performance. When the Enable (EN) input is low, the Output Enable (OE) is used to control the output current level. When the EN input is high, the device will transmit the input data to the output by clocking the data into the registers. The device also has an internal power-on reset circuit, which ensures that the output is always in the high-impedance state when power is first applied. The device can be used in a variety of applications, such as bus transceivers and peripheral interfaces.

In summary, the 74F646SPC is an advanced device that supports multiple applications, such as line drivers and D/A converters. It provides a logic level compatible output along with three levels of output current. Its internal reset circuit ensures that the output is always in the high-impedance state when power is first applied. The 74F646SPC also features a wide operating temperature range and its integrated thermal shutdown circuitry protects against device damage due to thermal overloads.
