SN74LV373APWR is a low-power, low-voltage CMOS octal latch, which is a part of the logic family of Integrated Circuit (IC) chips. The octal latch is mainly used to store digital data, which can be retrieved upon request. It is an important part of all advanced digital electronics, and it is widely used in most synchronous memory managing systems, telecommunication technologies and computer systems, etc.

This octal latch is designed in accordance with the industry standard, and is compliant with 16-pin DIP (Dual In-line Package) and 16C20T-08L-28™ packages. This device has two power supply options; one is the 3.3V (T version) and the other is 5.0V (L version). This device also offers a buffered data input, which has the capability to drive up to 15 outputs loads, and this results in high speed and low power operation. Additionally, this device has an enable (LE) pin, which can provide control over the data passing through it.

The SN74LV373APWR is essentially a “transparent” octal latch, which means that the data output will follow the data input if the enable (LE) pin is high. If the enable pin is low, the device will retain the data in its registers until the enable pin is set high again. This makes it ideal for applications such as data buffering and storing while the system is powered down or during system reset.

The SN74LV373APWR is made up of eight latches, each with its own clock input, data input, and output pins. In addition, there is an additional Clock Enable (CE) pin, which can be used to enable all eight latches simultaneously, allowing for latch-up without permanently losing the data. The data transfer from input to output is synchronous, meaning that the transition from data input to data output will be instantaneous. This makes the device suitable for use in fast, logic-intensive applications such as audio/video data multiplexing and digital audio encoding.

Compared to traditional TTL devices, the SN74LV373APWR has lowered power and voltage requirements, making it ideal for applications where battery power is limited. A minimal current draw of 3.3 mA (typical) or max 4.5 mA (max) makes it far superior to the 30 mA typically required by most TTL devices. This low current draw also results in a power dissipation of approximately 2.3W at a supply voltage of 3.3V.

Other features of the SN74LV373APWR include an undershoot/overshoot tolerant input stage, improved noise immunity, and low active-output current. The device’s output logic state is configured as N-channel MOSFET (as opposed to the standard P-channel MOSFETs) and can sink up to 24 mA for improved noise margin when driving non-CMOS loads.

In summary, the SN74LV373APWR is a low-voltage, low-power CMOS octal latch designed for numerous applications such as data buffering, digital audio encoding and audio/video multiplexing. Its low power consumption and small form factor makes it ideal for applications operating on battery power. Additionally, its built-in buffered data input means that it can drive up to 15 output loads, making it suitable for logic-intensive operations. Its undershoot/overshoot tolerant input stage and improved noise immunity make it suitable for solving even the most advanced digital problems.
