TMC2111AB2C1

Overview

The TMC2111AB2C1 is a variable-length shift register manufactured by Fairchild Semiconductor. It utilizes high-speed, low-power CMOS technology to ensure reliable data transfer. The device features an 8-bit output data bus width and is housed in a 24-pin ceramic DIP package with glass body material. It operates within a supply voltage range of 4.75 V to 5.25 V, with a nominal voltage of 5 V. The component supports through-hole mounting and functions as a fully synchronous byte-wide shift register programmable for lengths between 1 and 16 stages.

Feature Summary

• Fully synchronous byte-wide shift register architecture
• Programmable stage length ranging from 1 to 16 stages
• High-speed, low-power CMOS technology implementation
• Reliable data transfer capabilities

Applications

• Data storage systems requiring variable-length buffering
• Digital signal processing interfaces
• Industrial control logic circuits

Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor's semiconductor division was acquired by onsemi. Ensure the part number matches the specific CDIP-24 package configuration. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Check for any obsolescence notices or lifecycle changes associated with the original Fairchild branding versus current onsemi distribution channels.

Selection Notes

Select this component when a synchronous shift register with adjustable depth is required. The 24-pin ceramic DIP package suits applications needing robust physical durability and through-hole mounting. The 5V nominal supply voltage aligns with standard TTL/CMOS logic families. Consider the 8-bit parallel output width for efficient data retrieval compared to serial-only alternatives.

Part Context

This component belongs to the TMC2111A family of variable-length shift registers. These devices are designed for applications requiring flexible data storage depths without changing hardware. The TMC2111AB2C1 variant specifically denotes the ceramic DIP packaging option, distinguishing it from plastic or surface-mount equivalents within the same functional family.

Replacement Considerations

Check for direct substitutes from onsemi, which now holds the rights to the Fairchild product line. Verify pin compatibility and electrical specifications against other 24-pin ceramic DIP shift registers if sourcing from alternative vendors. Ensure the replacement supports the same 1-to-16 stage programmability.
