74HC40105PW,118

Overview

The Nexperia 74HC40105PW,118 is an asynchronous FIFO memory IC housed in a 16-TSSOP surface-mount package. It provides a storage capacity of 64 bits organized as 16 words by 4 bits. The device supports unidirectional data bus direction and operates on a supply voltage range of 2 V to 6 V. Key performance metrics include a maximum data rate of 36 MHz and an access time of 34 ns. It functions within a temperature range of -40°C to +125°C.

Applications

• Buffering data streams between components operating at different clock speeds
• Temporary storage for serial-to-parallel or parallel-to-serial conversion tasks
• Data buffering in microcontroller peripheral interfaces

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure the selected packaging variant matches the intended automated assembly process requirements.

Selection Notes

Select this component when a compact, low-voltage asynchronous buffer is required for 4-bit wide data paths. The 16-word depth suits applications needing minimal latency without complex control logic. Verify that the 2V to 6V supply range aligns with the system's power architecture and that the 34ns access time meets the timing constraints of the target interface.
