74F373PC

Logic - Latches

The 74F373PC is an 8-bit transparent latch designed with three-state outputs for bus-oriented applications. It is characterized for operation over the full military temperature range of -55°C to 125°C. The latch holds the states of the inputs until the chip is enabled. This allows data transfer between two points without the need for a constant data path.

Application Fields

This latch is commonly used in address buses and other data buses. It can be used to transfer signals between two processing units and allows for data to be stored for short periods of time. It is also used in low-power systems, where the low power consumption limit the speed or performance. The latch can also be used to separate one part of a computer from another, creating two distinct buses.

Working Principle

The 74F373PC latch operates by monitoring the voltage level of two inputs. Once an enable signal is given, the voltage level of the inputs is held for a short period of time. It works by amplifying the input signal by transistors and storing the output using capacitors. When the enable signal is received, the current is sent to ground, which stores the output. When the enable signal is removed, the current returns and the capacitor sends the stored signal back to the output.

The latch is ideal for low-power applications because it uses no power when the enable signal is not received. Because of the use of capacitors, the device will consume a maximum of 5µA when switched on. This makes it an ideal solution for applications requiring low power consumption without compromising on performance.

The latch is also capable of driving up to 24mA in total from its outputs. This allows the device to be used in applications where large numbers of devices need to pass off data quickly and efficiently.

In summary, the 74F373PC is a highly reliable 8-bit latch designed to transfer data between two points without the need for a constant data path. Ideal for low-power applications, the latch is capable of driving up to 24mA from its outputs. The device is characterized for operation over the full military temperature range of -55°C to 125°C, making it suitable for a wide range of industrial, commercial and automotive applications.
