Overview
The SN74ACT3638-20PCB is a bi-directional synchronous FIFO memory device manufactured by Texas Instruments. It features a storage capacity of 512 words by 32 bits, organized as two independent 512x32 blocks. The component operates with a maximum access time of 20 nanoseconds and utilizes a 120-pin High-Low Profile Quad Flat Package (HLQFP). Designed for CMOS technology, it supports positive logic operation and functions within a standard commercial temperature range of 0 to 70 degrees Celsius.
Feature Summary
- Bi-directional data transfer capability allowing simultaneous read and write operations across separate clock domains.
- Synchronous architecture ensuring precise timing control for high-speed digital signal processing applications.
- Dual independent memory banks providing flexible data buffering and flow control mechanisms.
Applications
- High-speed data buffering in telecommunications equipment
- Interface bridging between asynchronous system components
- Digital signal processing pipeline staging
Procurement Notes
Verify the specific speed grade suffix corresponds to the required performance specifications. Confirm package compatibility with existing PCB footprints. Check RoHS compliance status as indicated by distributor listings. Ensure supply chain authenticity through authorized channels.
Selection Notes
Select this component when dual independent 32-bit wide FIFO buffers are required. Consider the 120-pin HLQFP package constraints for board layout. Evaluate power consumption requirements against system thermal limits. Verify voltage level compatibility with interfacing logic families.
Part Context
This part belongs to the SN74ACT series of advanced CMOS logic devices. It serves as a specialized memory solution within Texas Instruments' industrial logic portfolio. The device addresses needs for high-density data buffering in complex digital systems requiring reliable synchronous operation.
Replacement Considerations
Check for SN74ACT3638-30PCB if slower switching speeds are acceptable. Verify pinout compatibility before substituting with other 120-pin FIFO variants. Consult official datasheets for electrical parameter differences.
