CGS2535VX

Clock Buffers, Drivers Overview

The CGS2535VX is an obsolete commercial-grade clock fanout buffer from Texas Instruments, part of the ABT family. It features a non-inverting 4-input to 16-output configuration in a 28-pin PLCC package. The device supports both 3.3V and 5.0V supply voltages with 5V-tolerant inputs. Key electrical specifications include symmetric output current drive of 24 mA (IOH/IOL), maximum propagation delay of 4.5 ns at 5V, and ensured pin-to-pin skew of 350 ps. It operates within a temperature range of 0°C to +70°C.

Clock Buffers, Drivers Feature Summary

• Non-inverting 4-to-16 clock driver optimized for high-speed memory arrays
• Dual voltage operation: 3.0V–3.6V or 4.75V–5.25V
• Ensured 350 ps output-to-output skew variation
• Symmetric 24 mA output current drive capability

Clock Buffers, Drivers Applications

• High-speed memory array driving
• Large fanout clock distribution systems
• Address bus buffering for CPU and I/O interfaces

Clock Buffers, Drivers Procurement Notes

This component is officially classified as obsolete by Texas Instruments. Verify availability through secondary market distributors or surplus suppliers. Confirm that the specific ordering suffix 'VX' corresponds to the standard PLCC tape-and-reel packaging variant described in the SNOS708C datasheet.

Clock Buffers, Drivers Selection Notes

Select this device when a non-inverting 1:4 expansion to 16 outputs is required for CMOS-compatible clock signals. Ensure the design accommodates the 28-pin PLCC footprint. For industrial temperature ranges (-40°C to +85°C), consider the CGS2535TV variant instead.

Clock Buffers, Drivers Part Context

The CGS2535 belongs to the CGS253x series, which includes variants like the CGS2534, CGS2536, and CGS2537. These drivers were engineered to reduce capacitive loading on address buses compared to conventional buffers, minimizing overshoot and undershoot in large buswidth designs.

Clock Buffers, Drivers Replacement Considerations

The CGS2535TV is the industrial temperature grade equivalent. No direct modern replacement is specified in the documentation; legacy inventory or functional equivalents from other manufacturers must be evaluated for pin compatibility and electrical parameters.
