Frequently Asked Questions
What logic family does the SN74LVTH373DWG4 belong to?
The SN74LVTH373DWG4 belongs to the LVT (Low Voltage Technology) logic family from Texas Instruments, which operates at 2.7V to 3.6V supply voltage while tolerating 5V inputs, making it compatible with mixed-voltage digital systems.
What is the output drive capability of the SN74LVTH373DWG4?
The SN74LVTH373DWG4 provides a maximum output low current (Iol) of 64mA per output, which is sufficient to directly drive heavily loaded bus lines with multiple receivers in microprocessor and memory interface applications.
How does the enable input work on the SN74LVTH373DWG4?
The SN74LVTH373DWG4 uses an active-low enable (LE) input. When the enable is asserted low, the latch is transparent and the outputs follow the D inputs. When deasserted high, the latch retains the last state of the inputs.
What package does the SN74LVTH373DWG4 come in?
The SN74LVTH373DWG4 is available in a 20-Pin SOIC (Small Outline Integrated Circuit) package, a widely used surface-mount package with good thermal performance and compatibility with standard automated assembly processes.
What applications is the SN74LVTH373DWG4 designed for?
The SN74LVTH373DWG4 is designed for bus latching in microprocessor address and data bus interfaces, memory controllers, FPGA I/O expansion, and mixed 3.3V/5V digital systems requiring 8-bit transparent latching with 3-state bus sharing capability.
