74HC573 Description

Short technical summary and product information.

The 74HC573 from HXY is an 8-bit D-type transparent latch designed for bus-oriented applications. It features 3-state non-inverting outputs, controlled by a common output enable (OE) input. The latch enable (LE) input allows data to be stored when LE transitions from HIGH to LOW.

This device supports a wide supply voltage range from 2.0 V to 6.0 V and operates within an extended temperature range of -40 °C to +125 °C. Key electrical characteristics include a typical propagation delay of 14 ns and output currents of -7.8 mA (high level) and 6 mA (low level). The latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

The 74HC573 is available in a TSSOP20 package, designed for surface mounting. Its inputs and outputs are positioned on opposite sides of the package, facilitating easy interfacing with microprocessors and microcomputers. This makes it a versatile component for use as an input or output port in various digital systems.
