Additional Details

The TC74AC373F features eight D-type latches, each with a data input (D) and a data output (Q). The latch is transparent when the enable input (LE) is high, allowing the data at the D input to pass directly to the Q output. When the LE input is low, the latch stores the data that was present at the D input at the time of the transition. The device also includes an output enable (OE) input, which, when high, disables the outputs, allowing them to be connected to a common bus. The TC74AC373F is available in a variety of packages, including SOIC and TSSOP. The device is typically used in microprocessor systems for address decoding and data buffering. The high output drive capability allows the device to drive multiple loads without significant degradation of signal quality. The wide operating voltage range makes it suitable for use in a variety of applications. The TC74AC373F is a reliable and versatile logic device for a wide range of digital applications.
