Product details

Overview

CCBTLV3861IPWRQ1 from Texas Instruments is a low-voltage 10-bit FET bus switch qualified for automotive applications, featuring 5-Ω on-state resistance, rail-to-rail switching across A/B ports, and I_off support for partial-power-down operation. It enables high-speed bidirectional data routing in CAN/LIN interface subsystems, infotainment backplanes, and ADAS sensor hub interconnects.

For engineers reviewing the CCBTLV3861IPWRQ1 datasheet, CCBTLV3861IPWRQ1 pinout, CCBTLV3861IPWRQ1 application, or CCBTLV3861IPWRQ1 equivalent, key selection criteria include its 24-pin TSSOP package, −40°C to 85°C automotive temperature range, 2.3–3.6 V supply compatibility, and flowthrough architecture optimized for PCB layout efficiency.

Technical Context

This device implements ten independent FET-based analog switches with complementary control logic: OE low enables A↔B conduction; OE high isolates both ports into high-impedance states. Its I_off protection ensures <10 μA leakage when V_CC = 0 V and any I/O biased 0–3.6 V, preventing backflow during power sequencing.

Switching performance is defined by propagation delay (t_pd) ≤ 0.25 ns at V_CC = 2.5 V, enable time (t_en) ≤ 5.5 ns, and disable time (t_dis) ≤ 5.8 ns - all measured under 30 pF load. On-resistance variation is tightly controlled: r_on = 5–8 Ω at V_CC = 2.3 V and II = 24 mA, with <15 Ω max at V_CC = 3.3 V and VI = 2.4 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.3 V to 3.6 V - supports dual-supply systems and battery-backed 3.3 V domains without level shifters
r_on (Max)	8 Ω at 2.3 V - ensures minimal signal attenuation and voltage drop for 100 Mbps digital buses
t_pd	0.25 ns typical - preserves signal integrity in high-speed parallel data paths like memory expansion interfaces
I_off	10 μA max at V_CC = 0 V - guarantees safe isolation during hot-swap or partial-power-down sequences
Operating Temp	−40°C to +85°C - meets AEC-Q100 Grade 2 requirements for under-hood and cabin electronics
Package	TSSOP-24 (PW) - 7.8 mm × 4.4 mm footprint with 0.65 mm pitch, compatible with standard SMT reflow profiles
Latch-up	>100 mA per JESD78 Class II - eliminates risk of destructive latch-up in noisy automotive environments

Pinout & Package

TSSOP-24 (PW) package: 7.8 mm × 4.4 mm body, 0.65 mm lead pitch, 1.2 mm max height, exposed metal pad not electrically connected. RoHS-compliant NIPDAU finish, MSL Level-1 (260°C peak reflow).

Pin/Terminal	Circuit Role	Design Meaning
1, 24	No internal connection (NC)	Unused pins; must remain unconnected to avoid parasitic coupling or ESD path disruption
2–11	A1–A10	Input/output port A side - bidirectional data terminals with rail-to-rail voltage handling (−0.5 V to 4.6 V)
12	GND	Power ground reference - requires low-inductance connection to system ground plane for noise immunity
13	V_CC	Supply voltage input - decoupling capacitor (0.1 μF ceramic) required within 5 mm for stable switching
14	OE	Active-low output enable - tie to V_CC via ≥10 kΩ pullup to ensure high-Z state during power-up/down
15–23	B1–B10	Input/output port B side - electrically identical to A-side; forms 10-bit bidirectional switch matrix with A

Key Features

Feature	Design Value
Rail-to-rail analog switching	Supports signals from −0.5 V to V_CC + 0.5 V - enables direct interfacing with legacy 5 V logic and mixed-voltage SoCs
Flowthrough pinout	A1–A10 and B1–B10 aligned linearly across package - minimizes trace length and crosstalk in dense PCB layouts
I_off partial-power-down	Blocks current flow when V_CC = 0 V - allows live insertion of modules while main power remains active
Low on-capacitance	C_io(OFF) = 5 pF - reduces loading on high-speed buses and preserves signal rise/fall times
Automotive qualification	AEC-Q100 Grade 2 certified - validated for vibration, thermal cycling, and ESD robustness in vehicle ECUs

Equivalent & Alternatives

The following parts are listed as comparable options for similar FET bus switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTLV3861QPWRQ1	Same silicon die, identical electrical specs, but marked with alternate top-side marking 'CL3861Q1' and different reel packaging (G4 variant)	No functional difference - used interchangeably in same automotive designs where reel logistics differ	Select based on distributor inventory and tape-and-reel configuration requirements (2000 vs. custom SPQ)
SN74LVC1G3157QDRYRQ1	Single-pole double-throw (SPDT) switch, 3.6 V max V_CC, 6 Ω r_on, but only 1 channel - not scalable to 10-bit width	Suitable for point-to-point signal routing (e.g., antenna switching), not parallel bus isolation	Choose only when application requires discrete channel control rather than simultaneous 10-bit switching

Compared with CCBTLV3861IPWRQ1, SN74CBTLV3861QPWRQ1 offers identical functionality with minor packaging logistics variance, while SN74LVC1G3157QDRYRQ1 provides channel-level flexibility at the cost of bus-width scalability - making CCBTLV3861IPWRQ1 optimal for parallel data path isolation.

FAQ

What is the maximum operating voltage for CCBTLV3861IPWRQ1?

The CCBTLV3861IPWRQ1 supports a supply voltage range of 2.3 V to 3.6 V. Its absolute maximum ratings allow V_CC up to 4.6 V, but sustained operation above 3.6 V violates recommended conditions and may impact reliability or parametric compliance. All electrical characteristics-including r_on, t_pd, and I_off-are guaranteed only within the 2.3–3.6 V window specified in the datasheet.

Does CCBTLV3861IPWRQ1 support hot-swap or partial-power-down operation?

Yes, CCBTLV3861IPWRQ1 includes I_off circuitry that limits leakage current to ≤10 μA when V_CC = 0 V and any I/O terminal is biased between 0 V and 3.6 V. This feature enables safe partial-power-down operation in modular automotive ECUs, preventing backflow current from powered subsystems into unpowered sections - a critical requirement for gateway and domain controller architectures.

What is the pinout configuration of CCBTLV3861IPWRQ1 and how does it affect PCB layout?

CCBTLV3861IPWRQ1 uses a flowthrough TSSOP-24 pinout: A1–A10 occupy pins 2–11, GND (pin 12), V_CC (pin 13), OE (pin 14), and B1–B10 occupy pins 15–23. This linear arrangement allows straight-through routing with minimal trace skew, reducing crosstalk and simplifying impedance-controlled layout for high-speed parallel buses - a key advantage over staggered or folded pinouts in space-constrained automotive modules.

How does the latch-up immunity of CCBTLV3861IPWRQ1 benefit automotive applications?

CCBTLV3861IPWRQ1 exceeds 100 mA latch-up immunity per JESD78 Class II, verified under worst-case transient conditions. This protects against destructive latch-up events triggered by load-dump spikes, jump-start surges, or ESD events in 12 V vehicle electrical systems - ensuring robust operation in engine bay, chassis, and powertrain control units where such disturbances are common.

Can CCBTLV3861IPWRQ1 be used in non-automotive industrial applications?

Yes, CCBTLV3861IPWRQ1 is fully functional in industrial settings, with its −40°C to +85°C operating range, 2.3–3.6 V supply compatibility, and rail-to-rail I/O supporting mixed-voltage systems. While qualified to AEC-Q100 for automotive use, its specifications - including 5 Ω r_on, 0.25 ns t_pd, and I_off - deliver measurable benefits in industrial PLC backplanes, test equipment multiplexers, and medical imaging data paths where signal fidelity and power sequencing matter.
