DS0026CMM

Overview

The DS0026CMM is a dual high-speed MOS driver manufactured by Texas Instruments, originally from the National Semiconductor portfolio. It functions as a fan-out buffer with two inputs and two outputs, supporting frequencies up to 10 MHz. The device operates within a temperature range of 0°C to 70°C and is housed in an 8-VSSOP surface-mount package. This component is designed for driving MOS gates in clock distribution applications.

Feature Summary

• Dual channel configuration providing 2:2 input-to-output buffering
• Maximum operating frequency of 10 MHz
• Surface-mount 8-VSSOP package (3.00mm width)
• Commercial temperature range operation (0°C to 70°C)

Applications

• MOS gate driving in clock distribution networks
• Fan-out buffering for digital logic signals

Procurement Notes

The DS0026CMM is listed as a discontinued product by Texas Instruments. Verification of availability through authorized distributors or surplus channels is required. Lead times and stock levels are subject to market conditions for end-of-life components.

Selection Notes

Select this component for dual-channel MOS driving requirements where a 10 MHz speed limit is sufficient. Ensure the design accommodates the commercial temperature range and the specific pinout of the 8-VSSOP package. Verify that TTL-compatible output levels meet the downstream MOS gate voltage thresholds.

Part Context

This part belongs to the DS0026 series of dual high-speed MOS drivers. It shares functional similarities with other National Semiconductor/TI legacy drivers like the UC1709 but is distinct in its specific 10 MHz specification and VSSOP packaging variant.

Replacement Considerations

Direct replacements may be limited due to the discontinued status. Consider evaluating similar dual MOS drivers from manufacturers such as Intersil (e.g., ISL55110) or Microsemi (e.g., SG1626), ensuring compatibility with voltage levels and package dimensions.
