M74HC237RM13TR

Overview

The M74HC237RM13TR is a high-speed CMOS 3-to-8 line decoder latch fabricated with silicon gate C2MOS technology. It features a supply voltage range of 2V to 6V, typical propagation delay of 16ns at 6V, and quiescent current of 4μA max. Outputs are low unless G1 is high and G2 is low. The device includes address latching controlled by GL, independent output enable controls (G1, G2), and protection against static discharge.

Feature Summary

• Integrated address latching mechanism for glitch-free decoding in stored-address applications
• Independent output enable control via active-high G1 and active-low G2 inputs
• High noise immunity with symmetrical output impedance and balanced propagation delays

Applications

• Bus-oriented systems requiring glitch-free decoders
• Stored-address applications in digital logic circuits
• Memory addressing and data routing implementations

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific SO-16 package variant matches design requirements. Check RoHS compliance status as indicated in official documentation. Ensure ESD handling protocols are followed during storage and assembly. Validate that the obsolete status does not impact long-term project viability.

Selection Notes

Select this component when a 3-to-8 decoder with integrated address latching is required. Consider the wide operating voltage range suitable for various logic families. Evaluate the high-speed performance characteristics for timing-critical bus applications. Verify pin compatibility with existing 74 series designs if migrating from older technologies.

Part Context

This part belongs to the M74HC237 family of 3-to-8 line decoder latches. It is designed for high-speed digital applications requiring stable decoded outputs.
