V62/22604-01XE

Overview

The V62/22604-01XE is a military-enhanced, radiation-tolerant 8-bit dual-supply bus transceiver with configurable voltage translation and tri-state outputs. It supports bidirectional data transfer between ports operating at independent supply voltages ranging from 0.65 V to 3.6 V. The device features multiple direction-control pins for simultaneous up and down translation, achieving speeds up to 380 Mbps when translating from 1.8 V to 3.3 V. It includes VCC isolation and partial power-down modes to prevent backflow current during power-down scenarios.

Feature Summary

• Radiation tolerant with single event latch-up immunity up to 43 MeV-cm2/mg and total ionizing dose acceptance testing up to 20 krad(Si).
• Fully configurable dual-rail design allows each port to operate with a power supply range from 0.65 V to 3.6 V.
• Multiple direction-control pins allow simultaneous up and down translation within a single device.
• VCC isolation feature effectively isolates both buses in a power-down scenario to limit backflow current.

Applications

• Low earth orbit (LEO) space applications
• Space radar systems
• Space communications equipment
• Space satellite payloads

Procurement Notes

Verify the specific V62/22604-01XE ordering suffix against the manufacturer's official documentation to confirm the exact radiation qualification level and package variant. Ensure that the procurement channel provides traceability to the Radiation Lot Acceptance Testing (RLAT) records required for space-grade components. Confirm compatibility with system voltage rails before finalizing orders.

Selection Notes

Select this component when interfacing devices operating at disparate voltage nodes, such as low-voltage processors with standard 3.3 V peripherals. The dual-supply architecture accommodates input voltages from 0.65 V to 3.6 V on both ports. Utilize the multiple direction control pins if simultaneous bidirectional translation is required without additional logic gates.
