HCF4050M013TR

Buffers, Drivers, Receivers, Transceivers Overview

The HCF4050M013TR is a hex non-inverting buffer manufactured by STMicroelectronics, belonging to the HCF logic series. It operates within a supply voltage range of 2 V to 6 V for CMOS applications and 4.5 V to 5.5 V for TTL-compatible variants. The device features six independent buffers in a single package, designed for high radiation hardness with a total ionizing dose (TID) rating of 50 krad (Si). It exhibits Single Event Latch-up (SEL) immunity up to 110 MeV.cm²/mg. The component supports an ambient temperature range from -55°C to +125°C and is available in hermetic packages compliant with ESCC specifications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific order includes hermetic packaging if required for the intended environment, as standard plastic packages may not meet the specified TID and SEL ratings. Confirm compliance with the relevant ESCC specification sheet corresponding to the exact part number variant. Ensure handling procedures account for moisture sensitivity if non-hermetic options are inadvertently selected.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits for space or high-radiation industrial applications where standard commercial parts would fail. Compare against other M54HCxxx series devices to ensure pin compatibility and logical function alignment. Verify that the chosen package type meets the thermal and mechanical constraints of the final assembly.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the M54HCxxx and M54HCTxxx family of CMOS functions produced by STMicroelectronics. These series are specifically engineered to satisfy the rigorous demands of the aerospace industry. The family encompasses various logic gates, flip-flops, multiplexers, and counters, all sharing common radiation hardening characteristics and extended temperature capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other M54HC4050 variants from STMicroelectronics or equivalent radiation-hardened hex buffers from qualified aerospace suppliers. Ensure any replacement maintains the same hermetic package style and ESCC qualification status to preserve system reliability.
