74LCX16841MTDX

Latches Overview

The Fairchild Semiconductor 74LCX16841MTDX is a D-type transparent latch featuring 20-bit parallel data storage. It operates within a supply voltage range of 2V to 3.6V and utilizes a 56-TSSOP surface-mount package. The device provides tri-state outputs with high drive capabilities, specified at 24mA for both high and low states. Propagation delay is typically 1.5ns, supporting high-speed digital applications across an operating temperature range of -40°C to 85°C.

Latches Feature Summary

• Provides 20-bit parallel data latching functionality with D-type transparency.
• Features tri-state outputs for effective bus line driving and isolation.
• Operates on a single 2V to 3.6V power supply for low-voltage compatibility.

Latches Applications

• Parallel-to-serial data conversion interfaces
• High-density memory buffer circuits
• Data acquisition system storage registers

Latches Procurement Notes

Verify the 'D' suffix indicates tape-and-reel packaging configuration against official datasheets. Confirm RoHS compliance status and specific lot traceability requirements prior to ordering. Ensure the 56-TSSOP footprint matches the target PCB design constraints.

Latches Selection Notes

Select this component when 20-bit synchronous storage is required in a compact form factor. The LCX series offers superior switching speeds compared to standard HC logic while maintaining CMOS input characteristics. Verify that the 24mA output current meets the load requirements of the destination circuitry.

Latches Part Context

This part belongs to the Fairchild 74LCX family of advanced low-voltage CMOS logic devices. The 74LCX16841 variant specifically addresses the need for wide-word data storage in portable and battery-operated systems where power efficiency and speed are critical performance factors.

Latches Replacement Considerations

Cross-reference with 74ALVC16841MTD for similar pinout but different voltage thresholds. Check 74HC16841 variants for higher voltage tolerance if the application exceeds 3.6V. Always verify electrical parameter compatibility before substituting.
