SN74ALS574BN Description

Short technical summary and product information.

The SN74ALS574BN is a D-type flip-flop from Texas Instruments, featuring 8-bit wide standard logic function with positive edge triggering and tri-state non-inverted outputs. It is designed for high-speed register and data storage applications.

Key electrical characteristics include a maximum clock frequency of 35 MHz, a propagation delay of 14 ns at 5V and 50 pF load, and a supply current of 18 mA. The device operates over a supply voltage range of 4.5V to 5.5V and a temperature range of 0°C to 70°C.

The component is housed in a 20-pin PDIP package (20-DIP 0.300" width), compatible with through-hole mounting. This package is suitable for prototyping, breadboarding, and applications where surface-mount is not required.
