CGS74CT2525M

Clock Buffers, Drivers Overview

The CGS74CT2525 is a 1-to-8 minimum skew clock driver belonging to the National Semiconductor FACT family, now under Texas Instruments. It distributes a single clock input to eight outputs with low skew during both high-to-low and low-to-high transitions. The device operates at a supply voltage of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 10.1 ns at 5.0V, symmetric output current drive of 24 mA for both sourcing and sinking, and guaranteed part-to-part skew of 3.5 ns. It features TTL-compatible inputs and provides 2 kV minimum ESD protection.

Clock Buffers, Drivers Feature Summary

• 1-to-8 Minimum Skew Clock Driver
• FACT Family Implementation
• TTL-Compatible Inputs ('CT)
• Symmetric 24 mA Output Drive

Clock Buffers, Drivers Applications

• Signal generation systems
• Clock distribution networks
• Systems requiring dual clock speeds (via compatible '2526 variant)

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix against the datasheet's simplified purchasing code table to confirm package type (e.g., M for SOIC) and temperature range (-40°C to +85°C). Ensure the specific revision matches the SNOS559 literature number. Confirm that the component meets the required environmental specifications for the intended operating conditions.

Clock Buffers, Drivers Selection Notes

Select the CGS74CT2525 when TTL-compatible inputs are required within the AC/ACT logic family. Choose this over the CGS74C2525 if the system requires strict 4.5V to 5.5V operation with defined TTL thresholds. Consider the CGS74CT2526 if a multiplexed clock input with SEL pin functionality is needed instead of a single straight clock input.

Clock Buffers, Drivers Part Context

This component is part of the CGS74C/CT2525/2526 series, which implements National Semiconductor's FACT technology. The '2525 variant provides a single clock input, while the '2526 offers multiplexed inputs. These devices are electrically identical to the 54AC/ACT2525 and 2526 series, ensuring compatibility across different product lines from National Semiconductor and Texas Instruments.

Clock Buffers, Drivers Replacement Considerations

The CGS74CT2525 is functionally identical to the 54ACT2525. Verify pinout compatibility and ensure the replacement supports the same 4.5V to 5.5V supply range and 24 mA drive current.
