The SN74F373 is an octal D-type transparent latch designed by Texas Instruments, featuring eight latches in a single package. It offers 3-state bus-driving true outputs, making it suitable for driving capacitive or low-impedance loads. The device allows full parallel access for loading data, and while the latch-enable (LE) input is high, the Q outputs follow the D inputs. When LE is low, the outputs are latched at the current D input levels. The SN74F373 includes a buffered output-enable (OE) input that can place the outputs in a high-impedance state, allowing for bus line driving without additional interface components. This functionality enables the retention of old data or the entry of new data while the outputs are disabled. The device operates within a supply voltage range of 4.5V to 5.5V and is characterized for operation from 0°C to 70°C. It is available in various package options, including a shrink small-outline package, which reduces PCB area while maintaining the same I/O pin count and functionality.
