MM74HC373WMX Integrated Circuits (ICs)

MM74HC373WMX is a type of IC that falls under the field of Logic Latches, from the high-speed CMOS Logic family. It is a dual 8-bit transparent latch that is capable of storing information whether the current power is attached or not. It has 3-state noninverting outputs for bus-oriented applications, such as computer busses, asynchronous peripheral lines, and data buffer and address latches. Its high-speed capability allows it to transfer data at up to 10MHz while consuming low power.

Physical Description

MM74HC373WMX is a dual 8-bit transparent latch with 3-state outputs designed for use in high-speed CMOS Logic applications. The package of this device is 20-TSSOP, which stands for "Thin Shrink Small Outline Package". It has 28 pins and measures 6.4mm x 3.9mm, which allows it to take up less board space compared to other packages.

Features and Benefits

• High Speed Performance - With a maximum clock frequency of up to 10MHz, MM74HC373WMX is capable of operating at very high speeds.
• Low Power Consumption - It has an active power consumption of 4mA.
• 3-state Non-inverting Outputs - This allows the device to be used in applications such as computer busses, asynchronous peripheral lines, and data buffer and address latches.

Circuit Design

The basic circuit diagram of the MM74HC373WMX consists of two 8-bit registers. Each register has eight data inputs and eight corresponding data outputs. Each register has an active-high Enable pin (E1 and E2) and an active-high clock pin (C). The device has Two 8-bit latch outputs (Q1 and Q2) which can be enabled with the active-high Output Enable pins (OE1 and OE2). The Output Enable pins (OE1 and OE2) of the register can also be tied together and controlled with a single active-high Output Enable pin (OE).

Working Principle

The operation of the MM74HC373WMX can be understood by looking at how each register works. When the clock signal is low, the data on the data inputs will be stored in the internal registers. When the clock signal transitions to high, the data on the data inputs will be transferred to the data outputs of each register. The data will be held in the register until the next active clock cycle. The active-high Enable pin (E1 and E2) must also be high for the data to be transferred between the data inputs and the respective data outputs. The active-high Output Enable pins (OE1 and OE2) must also be high for the data to be transferred from the data outputs of the register to the respective latch output (Q1 and Q2).

Application Fields

MM74HC373WMX is suitable for multiple applications, including asynchronous peripheral lines, such as serial ports, as well as address and data buffer applications. Due to its high speed performance and low power consumption, it is also suitable for use in bus-oriented applications, such as computer busses.

Conclusion

In conclusion, MM74HC373WMX is a type of IC that falls under the field of Logic Latches. It is a dual 8-bit transparent latch that is capable of storing information whether the current power is attached or not. It has 3-state noninverting outputs for bus-oriented applications, such as computer busses, asynchronous peripheral lines, and data buffer and address latches. Its features and benefits, including high speed performance and low power consumption, make it suitable for multiple applications.
