Logic-Latches is a form of electronic circuit that can hold and store a state. This type of circuit is used to control the flow of data or signals, and is most commonly found in digital logic circuits for use in computer systems and other electronic applications. The 74FCT373ATSOG8 is an 8-bit transparent latch family with multiple supply voltages and different packages which can be used in applications where a latch is required. It has four different configurations: dual transparent latch, dual latch-enable, four transparent latch and dual latch-enable/inhibit. In this article, we will discuss the application field and working principle of the 74FCT373ATSOG8.

Applications

The 74FCT373ATSOG8 can be used in a variety of applications such as digital logic, computer systems, and other electronic applications. These latches have low propagation delay, enable/inhibit latches, and support open latch, multiple supply voltages, and multiple packages. The 74FCT373ATSOG8 can be used to store information, synchronize data flow, control audio/video equipment, and provide buffering and synchronous switching capabilities in applications.

Working Principle of 74FCT373ATSOG8

The 74FCT373ATSOG8 is composed of 8 transparent latches in the same package. Each latch is composed of two four-sided, opposite facing gates to store 8 bits of data. It also has an extra Enable/Inhibit input which control access to the latch gates. On the rising edge of the input Enable/Inhibit signal, data is stored in the latch and kept until the falling edge of the signal. During this time, all the input signals are ignored. After the falling edge of the signal, the latched data is output out of the chip.

The 74FCT373ATSOG8 can be used in both dual-transparent latch and dual-latch-enable device. In Dual-transparent latch, a single-bit data is written on each rising edge of clock signal and a single-bit data can be written or read from each latch simultaneously. In Dual-latch-enable, data is only written to or read from the latch when the enable pin is activated. Data is written on each rising edge of clock signal and the output data is read when the enable signal goes low.

A multiple supply voltage of 1.65V to 3.6V can be used with the 74FCT373ATSOG8 and the supply current is 0.3mA. The output current is 4.0mA while the propagation delay is 12ns. Since the input signal has a high-impedance state, it has a wide-range of voltages between 0.8V to 3.6V that it can operate in. The chip also supports two different packages, a 48-pin and a 64-pin package.

Conclusion

The 74FCT373ATSOG8 is an 8-bit transparent latch family that is widely used in digital logic, computer systems, and other electronic applications. This family of latches supports multiple packages, multiple supply voltages, and low propagation delay. The main advantage of this latch is its high impedance state, which allows it to operate on a wide range of voltages, making it suitable for low-power applications. It is a reliable, cost-effective, and efficient way of controlling and transferring data.
