The 74LS373M013TR is a high-quality, octal transparent D-type latch produced by STMicroelectronics, one of the leading manufacturers in the semiconductor industry. Designed with low-power Schottky technology, this integrated circuit (IC) is part of the 74LS logic family, which is well-known for its low power consumption and high speed.
This particular model, the 74LS373, features eight latches with 3-state outputs for bus organized systems applications. The device comes in a surface-mount package, specifically in a Thin Shrink Small Outline Package (TSSOP), which is ideal for applications where space saving is crucial. The part number suffix 'M013TR' indicates that the IC is provided in tape and reel packaging, making it suitable for automated assembly processes.

With its transparent latch feature, the 74LS373M013TR ensures that data on the input bus can be seen at the outputs while the latch-enable (LE) input is high. When LE is taken low, the data that was present at the inputs at the time the transition occurred is retained at the outputs until the latch is enabled again.
The 3-state outputs are controlled by the output enable (OE) input. When OE is low, the outputs are active and reflect the data that is latched. When OE is high, the outputs are in a high impedance state, which effectively disconnects them from the bus, allowing for multiple devices to be connected to the bus without interference.
Overall, the 74LS373M013TR from STMicroelectronics is a reliable and functional choice for designers who require a high-performance octal latch for their digital systems. Its low power consumption, high speed, and ease of integration make it a versatile component for a wide range of applications in computing, telecommunications, and industrial systems.
