SN74HC573A Description

Short technical summary and product information.

The SN74HC573A from Texas Instruments is an octal transparent D-type latch featuring 3-state outputs. This design is optimized for driving highly capacitive or low-impedance loads, making it ideal for applications such as buffer registers, I/O ports, and bidirectional bus drivers.

 

Key electrical characteristics include a wide operating voltage range from 2V to 6V, a typical propagation delay of 21 ns, and a low maximum supply current of 80 µA. The outputs can drive bus lines directly with a high-current capability of ±6 mA at 5V. Input current is also minimized at a maximum of 1 µA.

 

The device utilizes a bus-structured pinout for efficient board layout. It is available in various packages including SOIC, TSSOP, and PDIP, with surface mount being a common mounting type. The operating temperature range is -40°C to 85°C.
