Product details
Overview
V62/14606-01XE-T from Texas Instruments is a dual 1-bit FET bus switch IC designed for high-bandwidth signal gating in military-grade systems. It operates from 2.3 V to 3.6 V, delivers 4 Ω typical ON-state resistance (ron), supports 0–5 V rail-to-rail analog/digital switching, and features Ioff partial-power-down protection. Used in USB interface isolation and differential signal routing within aerospace data acquisition subsystems.
For engineers reviewing the V62/14606-01XE-T datasheet, V62/14606-01XE-T pinout, V62/14606-01XE-T application, or V62/14606-01XE-T equivalent, key selection criteria include guaranteed –55°C to 125°C operation, 5-V-tolerant I/Os with device powered up or down, 3.5 pF typical OFF-state I/O capacitance, and bidirectional zero-propagation-delay switching under 2.3–3.6 V supply.
Technical Context
The V62/14606-01XE-T implements two independent 1-bit switches using charge-pump-enhanced NMOS pass transistors to maintain flat, low ron across input voltage range. Each switch has dedicated OE control (1OE, 2OE) enabling independent enable/disable with 1.5 ns typical enable time (ten) at 3.3 V.
It supports true bidirectional signal flow with near-zero propagation delay (tpd ≤ 2.3 ns max at 125°C), rail-to-rail voltage handling (0–5 V on I/Os regardless of VCC), and robust isolation during power-off via Ioff circuitry that limits backflow current to 1 μA at VCC = 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - Ensures compatibility with 2.5 V and 3.3 V logic domains without level translation. |
| ron (Typ) | 4 Ω - Minimizes insertion loss and signal distortion in high-speed digital and analog paths. |
| Cio(OFF) (Typ) | 3.5 pF - Reduces capacitive loading on source and load circuits, preserving signal integrity up to 500 MHz. |
| VI/O Range | 0 V to 5.5 V - Enables interoperability with 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V signaling standards. |
| Operating Temp | –55°C to 125°C - Qualified for extended temperature operation in defense, aerospace, and medical electronics. |
| Ioff (Max) | 1 μA at VCC = 0 V - Prevents damaging current backflow during partial power-down or hot-insertion scenarios. |
| fOE (Max) | 20 MHz - Supports fast control toggling for dynamic bus segmentation in real-time systems. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, exposed pad not present, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for first 1-bit switch - drives internal EN signal to connect 1A ↔ 1B when low. |
| 2 | 1A | Data I/O port A of first switch - bidirectional, 5-V-tolerant, low-capacitance node. |
| 3 | 1B | Data I/O port B of first switch - electrically identical to 1A; no directionality imposed by IC. |
| 4 | GND | Ground reference for VCC and all I/Os - must be low-impedance for noise immunity and ron stability. |
| 5 | VCC | Positive supply (2.3–3.6 V) - powers internal charge pump and logic; also reference for VIH/VIL thresholds. |
| 6 | 2OE | Active-low enable for second 1-bit switch - independent control enables asymmetric bus partitioning. |
| 7 | 2B | Data I/O port B of second switch - isolated from 1A/1B when 2OE is high. |
| 8 | 2A | Data I/O port A of second switch - supports simultaneous or staggered switching with first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog/digital switching | 0–5 V I/O capability with 2.5 V or 3.3 V VCC - eliminates external level shifters in mixed-voltage systems. |
| Charge-pump gate drive | Elevates NMOS gate voltage above VCC - ensures low, flat ron across full VI/O range and temperature. |
| 5-V-tolerant I/Os (powered up/down) | Withstands 5.5 V on A/B pins even when VCC = 0 V - enables safe hot-swap and legacy interface integration. |
| Low OFF-state capacitance | 3.5 pF typical Cio(OFF) - minimizes crosstalk and timing skew in high-density PCB layouts. |
| Controlled baseline & traceability | One assembly/test/fab site, extended lifecycle, product-change notification - meets MIL-PRF-38535 Class V requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 1-bit bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3306CPWRE4 | Commercial-grade (–40°C to 85°C), no Ioff, higher ron (6 Ω typ), no charge pump. | Lacks extended temperature and partial-power-down support - unsuitable for aerospace or medical deployments. | Select only for cost-sensitive industrial control where full temp range and Ioff are not required. |
| ADG732BRUZ | 32-channel CMOS analog switch, 4.5 Ω ron, 125°C max, but no 5-V-tolerant I/Os and higher Cio(OFF) (15 pF). | Higher channel count but incompatible with hot-swap 5 V interfaces and less optimal for high-frequency signal paths. | Prefer for multi-channel analog multiplexing; avoid when 5-V tolerance or <5 pF OFF-capacitance is mandatory. |
Compared with SN74CBT3306CPWRE4 and ADG732BRUZ, the V62/14606-01XE-T uniquely combines military temperature range, 5-V I/O tolerance with VCC off, sub-5 pF OFF capacitance, and charge-pump-assisted ron flatness - making it the only qualified option for high-integrity, high-bandwidth bus gating in defense and medical platforms.

FAQ
What is the maximum operating junction temperature for V62/14606-01XE-T?
The V62/14606-01XE-T is rated for a maximum operating junction temperature of 150°C, with guaranteed functional operation from –55°C to 125°C ambient. This specification aligns with MIL-PRF-38535 Class V requirements and is validated through thermal characterization including θJA = 190.6°C/W and ψJB = 117.7°C/W metrics. The V62/14606-01XE-T maintains specified ron, Cio(OFF), and switching performance across this full range.
Does V62/14606-01XE-T support hot-swap operation with 5 V signals applied before VCC is powered?
Yes, the V62/14606-01XE-T supports hot-swap operation: its I/O ports tolerate 0–5.5 V regardless of VCC state, and the Ioff feature limits reverse current to ≤1 μA when VCC = 0 V. This allows safe connection of live 5 V buses (e.g., USB, LVDS) prior to system power-up. The device achieves this via integrated clamp diodes and power-down isolation architecture confirmed in the SCDS352 datasheet Section 6.3.
Can V62/14606-01XE-T be used for analog signal switching, and what is its bandwidth limit?
Yes, the V62/14606-01XE-T is explicitly qualified for analog signal switching, supporting 0–5 V rail-to-rail operation with 3.5 pF typical OFF-state capacitance and 4 Ω typical ON-state resistance. Its usable analog bandwidth exceeds 500 MHz, as verified by TI's CBT-C/CB3T/CB3Q family characterization (literature SCDA008). Performance remains stable across –55°C to 125°C, making it suitable for RF front-end gating and high-fidelity video routing.
What is the recommended pull-up resistor value for OE pins on V62/14606-01XE-T during power-up?
The OE pins of V62/14606-01XE-T should be tied to VCC via a pull-up resistor to ensure high-impedance state at power-up. The minimum resistor value is determined by the driver's current-sinking capability; TI recommends ≥10 kΩ for standard CMOS drivers. This prevents unintended switch activation during VCC ramp and is detailed in the "Power-Up Sequence" section of the SCDS352 datasheet, Figure 1 and associated text.
Is V62/14606-01XE-T pin-compatible with commercial SN74CB3Q3306A variants?
Yes, the V62/14606-01XE-T shares identical TSSOP-8 (PW) package dimensions, pinout, and electrical interface with commercial SN74CB3Q3306A variants such as SN74CB3Q3306APW and CCB3Q3306AMPWEP. All share the same top-side marking "U306AM", identical thermal metrics, and functionally equivalent logic behavior - enabling drop-in replacement in existing designs requiring extended temperature and enhanced reliability.
