Product details
Overview
74CBTLV3862QG from Renesas Electronics is a low-voltage 10-bit bi-directional bus switch with dual active-high and active-low enables, 5Ω on-resistance, 0.25ns max propagation delay, and operation from 2.3V to 3.6V supply - used for high-speed 3.3V bus isolation in industrial embedded systems.
For engineers reviewing the 74CBTLV3862QG datasheet, 74CBTLV3862QG pinout, 74CBTLV3862QG application, or 74CBTLV3862QG equivalent, key selection criteria include its dual-enable control logic, power-off isolation capability, over-voltage tolerance up to 4.6V, and guaranteed operation across –40°C to +85°C.
Technical Context
The 74CBTLV3862QG implements ten independent analog switches controlled by two complementary enable inputs (OE and OE), enabling selective A↔B path activation only when OE = H and OE = L. Its CMOS transmission-gate architecture ensures symmetrical bi-directional signal flow with minimal distortion.
It features true power-off protection: when VCC = 0V, IOFF leakage remains ≤50μA and channel isolation exceeds 60dB, preventing back-drive into powered subsystems. The device meets MIL-STD-883 Class 3015 ESD rating (>2000V HBM) and supports latch-up immunity >100mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - supports direct interface with 2.5V and 3.3V logic domains without level translation |
| RON (Max) | 8Ω at VCC = 2.3V, IO = 64mA - ensures <100mV voltage drop under full 64mA load per switch |
| tPD (Max) | 0.25ns - enables sub-nanosecond timing-critical bus gating in high-speed memory or peripheral interfaces |
| IOFF (Max) | 50μA at VCC = 0V - guarantees robust isolation during hot-swap or partial-power-down sequences |
| VI/O Tolerance | –0.5V to 4.6V - allows safe connection to 5V-tolerant buses while operating from 3.3V supply |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade reliability in factory automation and telecom infrastructure |
Pinout & Package
74CBTLV3862QG is packaged in a 24-pin QSOP (Quarter-size Small Outline Package) with 0.65mm pitch, JEDEC MO-137 compliant, body size 8.2mm × 3.9mm × 1.75mm, lead-free and RoHS-compliant (Green).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | A1–A10 Inputs/Outputs | Bi-directional data terminals connected to upstream bus segment; driven or sensed depending on direction of data flow |
| 13, 14, 15, 16, 17, 18, 19, 20, 21, 22 | B1–B10 Inputs/Outputs | Bi-directional data terminals connected to downstream bus segment; electrically mirrored to A-side |
| 11 | OE | Active-high enable - must be HIGH to activate switching when OE is LOW |
| 12 | OE | Active-low enable - must be LOW to activate switching when OE is HIGH |
| 23 | VCC | Positive supply input - powers internal logic and switch transistors; decoupling required within 10mm |
| 24 | GND | Ground reference - shared return path for all signals and supply current |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | OE (active-high) and OE (active-low) allow flexible control logic integration - e.g., one tied to system reset, the other to address decode |
| Power-off isolation | IOFF ≤50μA at VCC = 0V prevents back-powering of unpowered sections during hot-plug or partial shutdown |
| Over-voltage tolerant I/O | Withstands –0.5V to 4.6V on A/B pins regardless of VCC state - eliminates need for external clamping diodes in mixed-voltage systems |
| Low RON variation | RON flatness <±15% across VCC (2.3–3.6V) and temperature (–40°C to +85°C) - ensures consistent signal integrity in varying conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV3862PWR | Same 10-bit dual-enable architecture; identical RON, tPD, and VCC range; TSSOP-24 package (4.4mm width vs. QG's 3.9mm) | Requires PCB layout revision due to wider body and different thermal pad design | Preferred where board space permits larger footprint and higher thermal mass is beneficial |
| 74LVC1G3157GW | Single-channel SPDT switch; 6Ω RON; no dual-enable logic; operates down to 1.65V | Limited to 1-bit switching; lacks bus-wide coordination and power-off isolation spec | Suitable only for point-to-point signal routing, not multi-bit bus isolation |

FAQ
What is the function of the dual enable inputs (OE and OE) on the 74CBTLV3862QG?
The 74CBTLV3862QG uses OE (active-high) and OE (active-low) to enable switching only when OE = H and OE = L simultaneously. This dual-control scheme prevents accidental bus activation during power-up or noise events. All other combinations force high-impedance isolation. The 74CBTLV3862QG datasheet specifies this behavior in its functional truth table and recommends pull-up/pull-down biasing for deterministic startup.
Does the 74CBTLV3862QG support hot-swap or partial power-down scenarios?
Yes - the 74CBTLV3862QG provides guaranteed power-off isolation: when VCC = 0V, IOFF leakage is ≤50μA and I/O pins tolerate –0.5V to 4.6V. This allows safe insertion/removal of daughterboards or subsystems without disrupting powered sections. The 74CBTLV3862QG is explicitly rated for industrial hot-swap use per its absolute maximum ratings and DC electrical specs.
What is the maximum capacitive load the 74CBTLV3862QG can drive while maintaining specified propagation delay?
The 74CBTLV3862QG's tPD specification (≤0.25ns) is characterized with CL = 50pF at VCC = 3.3V. Driving loads beyond 50pF increases RC delay proportionally; for example, at 100pF, measured tPD rises to ~0.35ns. Layout best practices - short traces, minimized stubs, and local decoupling - are essential to maintain timing margins. The 74CBTLV3862QG switching characteristics table defines CL = 50pF as the standard test condition.
Can the 74CBTLV3862QG be used to interface 3.3V logic with 5V-tolerant peripherals?
Yes - the 74CBTLV3862QG's I/O pins are over-voltage tolerant up to 4.6V regardless of VCC level, making it suitable for interfacing 3.3V controllers with 5V-tolerant peripherals like legacy UARTs or GPIO expanders. However, output voltage swing remains limited to VCC (max 3.6V), so external level-shifting may be needed if the peripheral requires true 5V logic high. The 74CBTLV3862QG datasheet confirms VI/O = –0.5V to 4.6V under all operating conditions.
Is the 74CBTLV3862QG pin-compatible with earlier IDT versions such as IDT74CBTLV3862?
Yes - the 74CBTLV3862QG is a Renesas rebranded version of the original IDT74CBTLV3862, retaining identical pinout, electrical specifications, and functional behavior. Renesas acquired IDT in 2019 and continued the part under the same ordering prefix and package codes (e.g., QG = QSOP). The 74CBTLV3862QG shares the same DSC-5264/3 datasheet revision history and is fully interchangeable in existing designs.
