The part number SN74AHCT573QDWRQ1 refers to an 8-bit latch manufactured by Texas Instruments (TI). This device belongs to the AHCT family, which offers high-speed CMOS with TTL-compatible inputs and outputs. It has 8 independently controllable latched outputs in a triple-state configuration, allowing for bus contention avoidance. The "QDWRQ1" package indicates it is likely a specialized or environmentally-enhanced variant, possibly featuring improved thermal performance, in a small-outline package suitable for surface-mount technology. The chip operates within a voltage range of typically 2V to 6V and is designed for applications where low power consumption and high-speed operation are required.
