M74HC4514RM13TR

Overview

The M74HC4514RM13TR is a high-speed CMOS 4-to-16 line segment decoder with latched inputs, fabricated using silicon gate C2MOS technology. It operates within a wide voltage range of 2V to 6V. The device features four input latches (A to D) that store binary code to select one of sixteen active-high outputs while inhibiting the others when the inhibit input is low. Data transfers to latch outputs when the strobe input is high and retains information when strobe goes low. All inputs include protection against static discharge and transient excess voltage.

Feature Summary

• Provides 4-to-16 line decoding with latched inputs for stable address storage
• Includes dedicated inhibit and strobe control inputs for output enablement and data latching
• Features symmetrical output impedance and balanced propagation delays
• Equipped with input protection circuits against static discharge and transient voltages

Applications

• Binary coded address decoding in digital systems
• Data latching and storage interfaces requiring stable output selection
• Segment decoder applications for display or indicator control

Procurement Notes

Verify the component status as the datasheet indicates this part may be obsolete. Confirm availability through authorized distributors or secondary markets if standard supply channels are exhausted. Ensure the package type matches the required SO-24 or TSSOP-24 form factor. Check for updated replacement recommendations from STMicroelectronics before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high-speed decoding with input latching capabilities. Consider the operating voltage range of 2V to 6V and the temperature range of -55°C to 125°C. Verify that the package style (SO-24 or TSSOP-24) fits the board layout constraints. Ensure compatibility with existing 74 series logic levels if interfacing with legacy components.

Part Context

This device belongs to the M74HC4514 family of decoders/latches. It is pin and function compatible with the standard 74 series 4514. The RM13 suffix denotes the specific tape and reel packaging for the SO-24 variant. The product is manufactured by STMicroelectronics using their proprietary C2MOS technology for improved performance and power efficiency.

Replacement Considerations

Check for direct replacements from STMicroelectronics or other manufacturers offering equivalent 4-to-16 line decoders with latches. Verify pinout compatibility and electrical specifications such as voltage range and speed. Consider obsolescence status and lead times for alternative sources.
