V62/04702-01XE

Overview

The V62/04702-01XE is a military-grade enhanced product variant of the CD74HC40103, manufactured by Texas Instruments. It consists of an 8-stage synchronous down counter with a single active-low terminal count output. The device operates on a supply voltage range of 2 V to 6 V and supports extended temperature performance from -40°C to 125°C. It features both synchronous and asynchronous preset capabilities, allowing data loading via P0-P7 inputs. The component utilizes high-speed silicon-gate technology, providing balanced propagation delays and significant power reduction compared to LSTTL logic ICs.

Feature Summary

• Supports synchronous or asynchronous preset operations for flexible data initialization
• Cascadable in either synchronous or ripple mode using terminal enable and terminal count outputs
• Provides high noise immunity with NIH or NIL equal to 30% of VCC at 5 V
• Delivers standard output fanout capable of driving up to 10 LSTTL loads

Applications

• Military and defense electronic systems requiring controlled baseline components
• Synchronous digital counting applications utilizing high-speed silicon-gate technology
• Ripple mode cascaded counter designs for extended bit-width requirements
• Systems operating within extended temperature ranges of -40°C to 125°C

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm that the military qualification pedigree meets the project's reliability standards. Ensure all unused inputs are tied to VCC or GND to maintain proper operation. Check the latest package addendum for moisture sensitivity level ratings and peak reflow temperatures before assembly.

Selection Notes

Select this component when a robust 8-bit synchronous down counter is needed for harsh environments. It is suitable for designs requiring both synchronous and asynchronous preset functions. Consider its compatibility with LSTTL loads if interfacing with legacy logic families. Evaluate the extended temperature range against the operational environment requirements.

Part Context

This part belongs to the CD74HC40103-EP family, representing an enhanced product version designed for demanding applications. It shares functional characteristics with the catalog CD74HC40103 but includes additional qualification testing. The device is distinct from the QML-certified CD54HC40103, which targets specific military defense applications. It is housed in a 16-pin SOIC package.

Replacement Considerations

The catalog part number CD74HC40103 serves as a commercial equivalent. For QML-certified military requirements, the CD54HC40103 is the designated alternative.
