The 74FCT16952ETPVG8 is a high-performance, low-power low-voltage CMOS device designed for low-power applications. It is based on the FCT family of logic products. It has both an open-collector output buffer and an integrated 3-state buffer for off-board applications.

Application

The 74FCT16952ETPVG8 can be used in many different applications. It can be used as a receiver or driver in off-board applications, such as memory buses or bus extension cards. In particular, this part is useful when multiple devices are connected with long connections. It can also be used in communication and networking applications, such as Ethernet and ATM, where as a high-speed, low-power digital signaling solution.

Features

The 74FCT16952ETPVG8 offers many features that make it an attractive choice for off-board applications. It has a low propagation delay of 7.2ns for all outputs. This is important for high-speed signaling applications and faster communication. In addition, it has a low power consumption of 0.6 mW for all outputs. This helps to reduce power consumption, which can result in a lower overall system cost.

The 74FCT16952ETPVG8 also has a bus hold feature. This feature stops bus pins from changing state even when the bus is floating. This reduces the possibility of having unpredictable behavior due to transitions in the bus. The device also has a high fanout of 12. This helps reduce the amount of devices needed to drive larger buses, allowing for a more cost-effective solution.

Working Principle

The 74FCT16952ETPVG8 is based on the FCT family of logic devices. This family of CMOS logic devices is based on a static logic architecture. This means that there is no need to constantly refresh the logic in order to keep it in a known state. The logic is immune to the effects of noise and will remain in a known stable state until the next input transition.

The main component of the 74FCT16952ETPVG8 is the open-collector output buffer and the integrated 3-state buffer. The output buffer is responsible for driving the data lines, while the integrated 3-state buffer is used to establish high impedance when the device is not active. This allows multiple devices to be connected to a single bus without causing contention.

The open-collector buffer works by pulling the output line low when the output is active. When the output is inactive, the output line is then in a tristate, or high impedance state. The 3-state buffer will output a high or low depending on the logic level of the input. The integrated 3-state buffer then works to ensure that the line will remain in a high impedance state when the device is inactive.

The 74FCT16952ETPVG8 is designed for low-power applications. This is achieved by its low power consumption, its low propagation delay and its built-in bus hold feature. All of these features help to reduce the overall power consumption within a system, which helps reduce the cost of the system.

Conclusion

The 74FCT16952ETPVG8 is a low-power, low-voltage CMOS device designed for use in off-board applications. Its open-collector output buffer and integrated 3-state buffer are used to provide low propagation delay, while the bus hold feature helps to reduce the effects of noise. The device also has a low power consumption and a high fanout, making it an attractive choice for applications where power consumption and cost are important.
