Product details
Overview
74CBTLV3862PGG from Renesas Electronics is a low-voltage 10-bit bi-directional bus switch IC 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 and signal routing in industrial embedded systems.
For engineers reviewing the 74CBTLV3862PGG datasheet, 74CBTLV3862PGG pinout, 74CBTLV3862PGG application, or 74CBTLV3862PGG equivalent, key selection criteria include enable polarity support (OE and OE), power-off isolation capability, over-voltage tolerance up to 4.6V, and TSSOP-24 green package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The 74CBTLV3862PGG implements ten independent analog switches controlled by complementary enable inputs (OE active-low, OE active-high), enabling flexible bus gating logic without external inverters. Each switch supports true bi-directional signal flow with matched on-resistance across A/B terminals.
It features power-off protection: when VCC = 0V, IOFF leakage remains ≤50μA and channel isolation is maintained. The device meets MIL-STD-883 ESD ratings (>2000V HBM, >200V MM) and exceeds 100mA latch-up immunity per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - supports 2.5V and 3.3V system rails without level translation |
| RON (Typ.) | 5Ω at VCC = 3.3V, IO = 24mA - minimizes voltage drop and signal distortion in high-speed data paths |
| tPD (Max) | 0.25ns - enables sub-nanosecond timing integrity for DDR, PCIe, or parallel bus applications |
| IOFF (Max) | 50μA at VCC = 0V - ensures robust bus isolation during hot-swap or power sequencing |
| VI/O Tolerance | –0.5V to 4.6V - allows interfacing with 5V-tolerant peripherals while powered from 3.3V |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade reliability without derating |
Pinout & Package
TSSOP-24 green package (PGG suffix), 0.65mm pitch, 7.8mm × 4.4mm body size, exposed pad not present, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A10 | Input/Output Port A | Bi-directional data terminal pair for first 10-bit bus segment; electrically identical to B-side |
| B1–B10 | Input/Output Port B | Bi-directional data terminal pair mirroring A-side; no internal directionality or buffering |
| OE | Active-Low Enable | Drives all 10 switches ON when LOW; must be pulled to GND for enable |
| OE | Active-High Enable | Drives all 10 switches ON when HIGH; must be pulled to VCC for enable |
| VCC | Power Supply | Single 2.3–3.6V supply; powers internal control logic and switch bias circuitry |
| GND | Ground Reference | Common return path for all I/O and supply currents; required for proper switching threshold reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual-enable control logic | Independent OE (active-low) and OE (active-high) allow direct interface with both TTL- and CMOS-compatible controllers without external inversion |
| Power-off isolation | IOFF ≤50μA at VCC = 0V prevents back-driving of powered subsystems during hot-plug or partial power-down |
| 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 |
| Low on-state resistance | RON = 5Ω typical at 3.3V ensures <10mV drop at 2mA, preserving signal integrity in 50Ω–100Ω transmission lines |
Applications
| PCI Express Gen1 Interposer | Industrial PLC Backplane |
|---|---|
Use Scenario: Routing PCIe REFCLK and sideband signals between CPU and slot connectors with minimal skew. IC Role / Device Role / Timing Role: Bi-directional passive switch isolating clock and presence detect lines during slot reconfiguration. Use Value: 0.25ns tPD and 5Ω RON preserve jitter budget and maintain signal rise/fall monotonicity under 100MHz operation. | Use Scenario: Isolating modular I/O card data buses from main controller during hot-swap insertion/removal. IC Role / Device Role / Timing Role: Bus gate enabling/disabling 10-bit status and command channels based on card presence detection. Use Value: Power-off isolation (IOFF ≤50μA) prevents backfeed into unpowered modules, satisfying IEC 61000-6-2 hot-swap requirements. |
| DDR2 Memory Buffer | Test Equipment Signal Matrix |
Use Scenario: Selecting between two DDR2 memory banks sharing a common controller interface. IC Role / Device Role / Timing Role: Low-latency bidirectional switch enabling bank-select multiplexing without added timing uncertainty.

IC Role / Device Role / Timing Role: Programmable interconnect node supporting arbitrary A↔B path assignment via FPGA-controlled enables. Use Value: Dual-enable logic simplifies FPGA GPIO usage - one pin drives OE, another drives OE - eliminating need for LUT-based inversion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV3862PWR | Same 10-bit architecture, 5Ω RON, but in TSSOP-24 with different moisture sensitivity level (MSL3 vs MSL1); identical DC/AC specs | Pinout and functionally identical; suitable for same PCB footprint if MSL compliance aligns with assembly process | Select when TI-sourced supply chain or alternate tape-and-reel packaging is preferred |
| 74LVC1G3157GW | Single-pole double-throw (SPDT) switch, not 10-bit; RON = 6Ω, tPD = 0.2ns, but only 1 channel - requires 10x units for equivalent functionality | Not scalable to 10-bit bus; used where space permits discrete channel control and independent enable per path | Choose only for low-channel-count designs requiring per-line enable granularity |
Compared with SN74CBTLV3862PWR, the 74CBTLV3862PGG offers identical electrical performance and pinout but differs in MSL rating and reel packaging; versus 74LVC1G3157GW, it delivers integrated 10-bit switching with coordinated enable control - reducing component count, layout area, and enable signal routing complexity.

FAQ
What is the operating voltage range for the 74CBTLV3862PGG?
The 74CBTLV3862PGG operates from 2.3V to 3.6V, fully supporting both 2.5V and 3.3V logic systems. Its VI/O tolerance extends to –0.5V to 4.6V, allowing safe interfacing with higher-voltage peripherals even when VCC is at minimum. This range is validated across the full industrial temperature span (–40°C to +85°C), and the 74CBTLV3862PGG maintains specified RON, tPD, and leakage performance throughout.
Does the 74CBTLV3862PGG support power-off isolation?
Yes, the 74CBTLV3862PGG provides guaranteed power-off isolation: when VCC = 0V, IOFF leakage is limited to ≤50μA per channel, preventing back-driving of powered downstream circuits. This feature is explicitly characterized in the datasheet's DC Electrical Characteristics table and is essential for hot-swap and partial-power-down architectures. The 74CBTLV3862PGG achieves this without external components.
How do the dual enable inputs (OE and OE) function on the 74CBTLV3862PGG?
The 74CBTLV3862PGG uses complementary enables: OE (active-low) and OE (active-high). Both must be asserted simultaneously - OE = LOW and OE = HIGH - to turn ON all ten switches. Any other combination (e.g., both LOW or both HIGH) forces high-impedance isolation. This dual-control scheme eliminates race conditions and avoids undefined states during power-up, and is fully documented in the Function Table of the 74CBTLV3862PGG datasheet.
What package type does the 74CBTLV3862PGG use, and is it RoHS-compliant?
The 74CBTLV3862PGG uses a TSSOP-24 green package (suffix PGG), measuring 7.8mm × 4.4mm with 0.65mm lead pitch. It is RoHS-compliant and rated MSL1 (unlimited floor life), per the ordering information section of the official Renesas datasheet. No exposed thermal pad is present, and the package is compatible with standard SMT reflow profiles for lead-free assembly.
Can the 74CBTLV3862PGG replace older 74CBT or 74LVX series bus switches?
The 74CBTLV3862PGG is not a direct replacement for 74CBT or 74LVX devices due to differences in enable logic, voltage range, and RON behavior. While functionally similar as a 10-bit bus switch, the 74CBTLV3862PGG requires both OE and OE to be actively driven (not tied), and its 2.3–3.6V range excludes 5V operation. Migration requires validation of timing, enable drive strength, and power sequencing - the 74CBTLV3862PGG datasheet does not claim pin or functional compatibility with those families.
