Performance Characteristics

Fast 10ns access time enables high-speed data buffering

66.7MHz clock supports high throughput systems

Supports depth and width expansion for scalable designs

Bi-directional bus allows flexible data flow between subsystems

Maximum current draw is 40mA, making it efficient for most logic level designs

Works reliably in industrial temperature ranges

Application Environments

Used in data buffering, communications interfaces, and high-speed data acquisition

Suitable for networking equipment, industrial control, telecommunications systems, and memory expansion in embedded systems

Designed for use in environments requiring reliable operation from -40°C to 85°C

Selection Guidelines

Choose when you need fast and reliable FIFO operation in a 3V to 3.6V system

Ideal for applications where signal timing, data width, and expansion flexibility are important

Match the 64-TQFP footprint and 4.6K FIFO memory size to your board and data requirements

Confirm compatibility with your logic level and bus configuration

Since it is an obsolete part, consider lifecycle risks before design-in

Usage Considerations

Take note of moisture sensitivity (MSL 3, 168 hours floor life); handle and store appropriately before soldering

Device is sensitive to ESD; ensure safe handling during assembly

Be aware of the lack of retransmit capability and FWFT (First Word Fall Through) support

Confirm your inventory needs, as supply may be limited due to obsolescence

For RoHS and REACH compliance, this part meets current standards

Make sure the operating temperature matches your application

Potential Equivalent/Replacement Models
