Overview
The SN74ACT3638-30PCB is a synchronous, bi-directional FIFO memory IC manufactured by Texas Instruments. It features a dual circuit configuration with a memory depth of 512 words and a word width of 32 bits. The device operates at a maximum access time of 15 ns and requires a 5 V power supply. It is housed in a PQFP-120 package.
Feature Summary
- Supports bi-directional data transfer for flexible system integration
- Provides simultaneous read and write operations via synchronous control
- Integrates automatic retransmission functionality to enhance data integrity
Applications
- High-speed data buffering in communication systems
- Interface bridging between asynchronous logic blocks
- Data storage in digital signal processing pipelines
Procurement Notes
Verify the specific suffix '30' indicates the speed grade and 'PCB' denotes the package type against the official datasheet. Confirm RoHS compliance status as sources vary. Ensure the PQFP-120 footprint matches your PCB design before ordering.
Selection Notes
Select this component when a high-density, dual-port FIFO is required for 32-bit wide data paths. The synchronous operation ensures timing alignment with clocked systems. Consider the 15 ns speed for moderate-to-high frequency applications requiring reliable bi-directional flow.
Part Context
This part belongs to the SN74ACT series of advanced CMOS logic devices. It provides improved switching speeds and lower power consumption compared to standard LS logic families while maintaining compatible pinouts for legacy designs.
Replacement Considerations
Check for SN74ACT3638 variants with different speed grades or package options. Verify if non-TI equivalents support the same 512x32 configuration and bi-directional capabilities.
