Product details
Overview
74CBTLV3861PGG from Renesas Electronics is a low-voltage 10-bit bi-directional bus switch IC with 5Ω on-state resistance, operating from 2.3V to 3.6V supply, supporting industrial temperature range (–40°C to +85°C), and featuring power-off isolation and over-voltage tolerance for high-speed 3.3V bus switching applications.
For engineers reviewing the 74CBTLV3861PGG datasheet, 74CBTLV3861PGG pinout, 74CBTLV3861PGG application, or 74CBTLV3861PGG equivalent, key selection criteria include on-resistance (≤5Ω typ.), propagation delay (≤0.25ns), output enable/disable timing (≤4.5ns/≤5ns), isolation leakage (IOFF ≤50µA at VCC = 0), and TSSOP-24 package compatibility with high-density PCB layouts.
Technical Context
The 74CBTLV3861PGG implements ten independent analog switches controlled by a single active-low output enable (OE) input; when OE is low, A1–A10 are connected bidirectionally to B1–B10 with minimal RC delay; when OE is high, both ports enter high-impedance isolation.
It supports voltage translation across ports (VI/O tolerant to –0.5V to +4.6V), maintains latch-up immunity (>100mA), and guarantees safe operation during power sequencing via OE pull-up recommendation - critical for hot-swap and partial-power-down systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - enables direct interface with 2.5V and 3.3V logic domains without level shifters |
| RON (Typ.) | 5Ω - ensures <0.15ns propagation delay into 50pF load, preserving signal integrity in high-speed buses |
| tPD (Max) | 0.25ns - defines minimum achievable bus switching latency for timing-critical backplane or memory interconnects |
| IOFF (Max) | 50µA at VCC = 0 - guarantees robust port isolation during system power-down, preventing back-driving |
| VI/O Range | –0.5V to +4.6V - allows safe connection to higher-voltage peripherals without clamping diodes or external protection |
| ESD Rating | 2000V HBM / 200V MM - meets industrial IEC 61000-4-2 surge immunity requirements for board-level reliability |
| Operating Temp | –40°C to +85°C - qualified for deployment in industrial control, telecom infrastructure, and automotive under-hood modules |
Pinout & Package
74CBTLV3861PGG is housed in a 24-pin Thin Shrink Small Outline Package (TSSOP), 4.4mm width, 0.65mm pitch, JEDEC MO-153 compliant, with exposed pad not present. Pin 1 is top-left corner (dot-marked), pin count and layout match standard TSSOP-24 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A10 | Data Input/Output Port A | Bidirectional analog/digital signal terminals; electrically identical to B-side when switch enabled |
| B1–B10 | Data Input/Output Port B | Matched 10-bit counterpart to A-port; no internal directionality - fully symmetrical conduction |
| OE | Active-Low Output Enable | Drives all 10 switches simultaneously; must be pulled up to VCC during power-up to ensure default isolation |
| VCC | Positive Supply | Single 2.3–3.6V rail powers internal logic and switch bias; no separate I/O supply required |
| GND | Ground Reference | Common return for all signals and supply; decoupling capacitor placement near pin 12 is recommended |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional 10-bit switching | Enables flexible data path routing between two 10-bit buses without direction control logic overhead |
| 5Ω typical on-resistance | Minimizes insertion loss and signal distortion in 100MHz+ parallel bus applications |
| Power-off isolation | Guarantees <50µA leakage between A/B ports when VCC = 0 - essential for mixed-supply domain partitioning |
| Over-voltage tolerant I/O | Supports ±0.5V to +4.6V input range - eliminates need for external clamps when interfacing legacy 5V peripherals |
| Industrial temperature grade | Validated operation from –40°C to +85°C - suitable for uncontrolled ambient environments without thermal derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV3861PWR | Same 10-bit function, 5Ω RON, but TI package code PWR = TSSOP-24 with different moisture sensitivity level (MSL3 vs MSL1 for PGG) | Identical electrical behavior; differs only in tape-and-reel packaging and JEDEC-compliant marking format | Select when sourcing from TI-authorized channels or requiring TI-specific logistics handling |
| 74LVC1G3157GW,125 | Single-pole double-throw (SPDT) analog switch, not 10-bit; RON = 10Ω typ., max 3.6V VCC, but lacks bus-wide OE control | Only suitable for point-to-point signal routing, not parallel bus isolation; requires 10x devices plus glue logic for same functionality | Consider only for ultra-low-pin-count prototypes where full 10-bit integration is unnecessary |
Compared with SN74CBTLV3861PWR, 74CBTLV3861PGG offers identical switching performance and pinout but differs in MSL rating and reel packaging; versus 74LVC1G3157GW,125, it delivers integrated 10-bit control with single-OE simplicity - reducing component count, layout area, and timing skew in parallel data paths.

FAQ
What is the maximum operating voltage for the 74CBTLV3861PGG?
The 74CBTLV3861PGG supports a supply voltage range of 2.3V to 3.6V under normal operation. Its absolute maximum ratings allow VCC up to +4.6V and I/O voltages from –0.5V to +4.6V - enabling safe interfacing with higher-voltage peripherals without damage, though functional operation is guaranteed only within the 2.3–3.6V VCC window. This over-voltage tolerance is intrinsic to the device's design and does not require external clamping.
Does the 74CBTLV3861PGG support hot-plug operation?
Yes, the 74CBTLV3861PGG supports hot-plug operation due to its power-off isolation feature: when VCC = 0V, IOFF is limited to ≤50µA, preventing back-current flow between A and B ports. Combined with OE-controlled enable/disable and over-voltage tolerant I/O, this makes the 74CBTLV3861PGG suitable for modular systems where cards or modules are inserted or removed while the backplane remains powered.
What is the recommended pull-up resistor value for OE on the 74CBTLV3861PGG?
The datasheet specifies that OE should be tied to VCC through a pull-up resistor to ensure high-impedance state during power-up or power-down. The minimum resistor value depends on the current-sinking capability of the driving source; for standard CMOS drivers, a 10kΩ resistor is commonly used and verified to maintain VIH >2.0V at VCC = 3.6V. Lower values (e.g., 4.7kΩ) improve noise immunity but increase static current - design trade-offs depend on system-level noise and power budgets.
Can the 74CBTLV3861PGG be used for analog signal switching?
Yes, the 74CBTLV3861PGG functions as a low-distortion analog switch: its 5Ω on-resistance, flat RON vs. voltage profile, and 6pF CIO(OFF) capacitance support bandwidths exceeding 100MHz for small-signal AC coupling. It has been validated in applications such as audio multiplexing and sensor signal routing where DC-coupled integrity and minimal crosstalk are required - provided signal swing remains within the –0.5V to +4.6V I/O range and peak current stays below 128mA per channel.
Is the 74CBTLV3861PGG pin-compatible with other CBTLV-series bus switches?
No - the 74CBTLV3861PGG is a dedicated 10-bit bus switch in TSSOP-24; other CBTLV parts like the 74CBTLV3244 (octal) or 74CBTLV3257 (quad 2:1 mux) use different pinouts and logic configurations. While they share the same voltage range, RON target, and industrial temp grade, direct pin replacement is not supported. System-level redesign is required when substituting across CBTLV family members due to differing terminal assignments and functional groupings.
