M74HC251RM13TR

Overview

The M74HC251RM13TR is an 8-channel multiplexer with 3-state outputs fabricated using silicon gate C2MOS technology. It features true (Y) and complement (W) outputs controlled by a STROBE input. The device operates within a supply voltage range of 2V to 6V, providing high noise immunity with VNIH and VNIL minimums of 28% VCC. Propagation delay is typically 17ns at 6V, with symmetrical output impedance of 4mA minimum for both high and low states.

Feature Summary

• Provides both true and complementary outputs for flexible signal routing
• Features a STROBE input that places outputs in a high-impedance state when active
• Includes protection circuits against static discharge and transient excess voltage on all inputs

Applications

• Data routing in digital systems
• Signal selection in communication equipment
• Multiplexing applications requiring tri-state control

Procurement Notes

Verify the specific package type required for your design, as the RM13TR suffix indicates SOP packaging. Confirm lead availability directly with authorized distributors, as this component may be subject to discontinuation or limited stock. Ensure the operating temperature range meets your environmental requirements before finalizing procurement.

Selection Notes

Select this component when an 8-to-1 multiplexer with tri-state capability is needed. It is compatible with standard 74 series logic functions. Consider the wide operating voltage range and high noise immunity for robust performance in varying electrical environments. Verify pin compatibility if replacing existing designs.

Part Context
