V62/04703-01XE

Overview

V62/04703-01XE is a high-speed silicon-gate CMOS 5-stage Johnson counter with ten decoded outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an extended temperature performance from -40°C to 125°C. The device features fully static operation, buffered inputs, common reset functionality, and positive edge clocking. It provides enhanced diminishing manufacturing sources support and enhanced product-change notification.

Feature Summary

• Features a 5-stage Johnson counter architecture with ten sequentially decoded outputs that transition high on the low-to-high clock period.
• Includes a master reset input to set all decoded outputs to low except output 0, and a carry output for cascading multiple stages.
• Provides enhanced diminishing manufacturing sources support and enhanced product-change notification for long-term availability.

Applications

• Sequential timing control in digital logic circuits
• Decoded output generation for state machines
• Cascaded multi-stage counting applications

Procurement Notes

Verify the specific package type (SOIC or TSSOP) required for your design, as the V62/04703-01XE designation corresponds to the SOIC variant while the YE suffix indicates TSSOP. Confirm that the component meets your environmental requirements given the -40°C to 125°C operating range. Ensure all unused inputs are tied to VCC or GND to maintain proper device operation and prevent undefined states.

Selection Notes

Select this component when a robust, high-speed CMOS decade counter is needed for military or industrial environments requiring extended temperature ranges. It serves as a qualified alternative to standard catalog parts, offering enhanced supply chain stability through DMS support. Consider its 60 MHz maximum frequency capability at 5 V for high-speed sequential logic designs.

Part Context

This part belongs to the CD74HC4017-EP family, which represents the enhanced product version of the standard CD74HC4017. It is designed for applications requiring higher reliability and longer lifecycle support compared to commercial grade devices. The EP designation signifies qualification in accordance with JEDEC and industry standards for harsh environment operation.

Replacement Considerations

The standard catalog part CD74HC4017 is functionally equivalent but lacks the enhanced product qualifications. For automotive applications, the CD74HC4017-Q1 is available. Military specifications may require the CD54HC4017 variant. Verify pin compatibility and electrical characteristics before substituting.
