SN74AS574N Description

Short technical summary and product information.

The SN74AS574N is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. Designed for bus driving applications, it features 3-state outputs that are non-inverted. This component is suitable for implementing buffer registers, I/O ports, and working registers.

 

Key electrical characteristics include a maximum clock frequency of 90 MHz, an operating voltage range of 4.5V to 5.5V, and a maximum supply current of 116 mA. The maximum propagation delay is 9ns at 5V and 50pF. The device operates within a temperature range of 0°C to 70°C.

 

This flip-flop is packaged in a 20-pin PDIP format and is designed for through-hole mounting. The outputs are tri-state and non-inverted, allowing them to drive bus lines directly. The SN74AS574N is part of the AS technology family.
