V62/14606-01XE-T

Overview

The V62/14606-01XE-T is a military-grade dual FET bus switch from the SN74CB3Q3306A-EP series, manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports data I/O voltages up to 5.5 V. The device features high-bandwidth data paths with switching frequencies up to 20 MHz and low on-state resistance (typically 4 Ω). It provides rail-to-rail switching, bidirectional data flow, and isolation during partial-power-down modes via Ioff circuitry. Packaged in an 8-pin TSSOP (PW), it is qualified for extended temperature ranges from -55°C to 125°C.

Feature Summary

• High-bandwidth data path supporting broadband communications and networking applications
• Latch-up performance exceeding 100 mA per JESD 78 Class II standards
• Low and flat ON-state resistance enabling minimal propagation delay
• Controlled baseline manufacturing with product traceability

Applications

• USB interface signal routing
• Differential signal interface switching
• Bus isolation in data-intensive computing systems

Procurement Notes

Verify that the ordering suffix '-T' corresponds to the tube packaging configuration as specified in the TI Package Option Addendum. Confirm the part number matches the enhanced product designation SN74CB3Q3306A-EP to ensure compliance with defense, aerospace, and medical application requirements. Cross-reference the VID number and top-side marking U306AM against official documentation to validate authenticity.

Selection Notes

Select this component when designing circuits requiring high-speed signal switching with low distortion in harsh environments. The device is suitable for applications demanding 5-V tolerant I/Os while operating at lower core voltages. Ensure control inputs are driven by TTL or 5-V/3.3-V CMOS outputs to maintain proper logic levels. Consider the thermal characteristics of the TSSOP package for heat dissipation in dense layouts.

Part Context

This part belongs to the SN74CB3Q3306A-EP family, which utilizes a charge pump to elevate gate voltage for consistent ON-state resistance. It serves as a specialized version of the standard SN74CB3Q3306A, offering enhanced reliability and controlled manufacturing processes. The device integrates two independent 1-bit switches, allowing flexible configuration as either single-bit or dual-bit bus switches.

Replacement Considerations

The catalog equivalent SN74CB3Q3306A offers similar electrical characteristics but lacks the enhanced product controls and specific qualification for critical applications.
