Product details
Overview
74CBTLV1G125GM,115 from Nexperia is a single high-speed CMOS bus switch with active-low output enable (OE), 5 Ω typical ON-resistance at 3.3 V, rail-to-rail data I/O switching, and IOFF partial power-down protection. It operates from 2.3 V to 3.6 V across –40 °C to +125 °C and is used in low-voltage signal routing for portable computing and industrial interface isolation.
For engineers reviewing the 74CBTLV1G125GM,115 datasheet, 74CBTLV1G125GM,115 pinout, 74CBTLV1G125GM,115 application, or 74CBTLV1G125GM,115 equivalent, key selection criteria include guaranteed sub-0.25 ns propagation delay at 3.3 V, ±10 μA IOFF leakage at VCC = 0 V, Schmitt-trigger OE input tolerance to slow edges, and XSON6 (SOT886) package compatibility with 0.5 mm profile PCB stacking.
Technical Context
This device implements a single-pole, single-throw (SPST) analog switch controlled by an active-low OE input. Its CMOS transmission gate architecture enables bidirectional, rail-to-rail signal pass-through between A and B ports when enabled, with no internal level shifting or buffering.
The IOFF circuit actively disables both A and B terminals during power-down, blocking backflow current even when opposing supply rails remain active. Schmitt-trigger action on OE ensures reliable switching despite slow-rising control signals up to 20 ns/V transition rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - supports dual-supply systems and battery-powered 2.5 V/3.3 V logic domains |
| ON-resistance (RON) | Typ. 4.2 Ω at VCC = 3.0 V, ISW = 64 mA - ensures minimal voltage drop and signal attenuation in high-speed data paths |
| Propagation delay (tpd) | Typ. 0.16 ns at VCC = 3.3 V - enables use in >1 GHz digital signal routing without timing budget impact |
| IOFF leakage | ±10 μA at VCC = 0 V - prevents cross-coupling and power loss when host system powers down peripheral buses |
| Switch capacitance (Csw) | 10.3 pF (ON-state) - maintains signal integrity for USB 2.0, PCIe Gen1, and MIPI D-PHY interfaces |
| ESD rating | HBM >2000 V, CDM >1000 V - meets industrial-grade robustness requirements without external protection |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive infotainment and industrial motor control environments |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); 6-terminal, leadless, 1.0 × 1.45 × 0.5 mm body; wettable flank compatible for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Bidirectional data port - connects to source or sink node; supports rail-to-rail analog/digital signals |
| 2 | OE | Active-low output enable - Schmitt-trigger input tolerates slow edges; tie high via pull-up for power-up high-Z state |
| 3 | GND | Ground reference - must be connected directly to system ground plane to ensure ESD path and noise immunity |
| 4 | n.c. | No connection - electrically isolated terminal; no internal bond wire or silicon connection |
| 5 | VCC | Positive supply - powers internal logic and switch transistors; decoupling capacitor required within 2 mm |
| 6 | B | Bidirectional data port - mirror of Pin 1; identical electrical characteristics and routing constraints |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full VCC-to-GND signal swing on A/B ports without clipping or distortion |
| IOFF partial power-down mode | Blocks backflow current when VCC = 0 V, enabling hot-swap and dynamic power gating |
| 5 Ω typical ON-resistance | Minimizes insertion loss and reflection in high-frequency data lines up to 263 MHz (-3 dB) |
| Schmitt-trigger OE input | Accepts slow-rising control signals (≤20 ns/V) without oscillation or metastability |
| Overvoltage-tolerant control inputs | OE accepts up to 3.6 V regardless of VCC setting - simplifies mixed-voltage system interfacing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT1G125DBVR | Higher RON (7 Ω typ. at 3.3 V); no IOFF; SOT-23-5 package | Lacks partial power-down capability; unsuitable for hot-swap or multi-rail systems | Select only if board layout requires through-hole-compatible footprint and IOFF is not required. |
| 74LVC1G125GW,125 | Buffered output (non-passive); 3.6 V tolerant inputs; TSSOP5 package | Introduces propagation delay (~3 ns) and cannot pass analog signals; unidirectional only | Choose only when digital-level-shifting buffer function is needed instead of true analog switching. |
Compared with SN74CBT1G125DBVR and 74LVC1G125GW,125, the 74CBTLV1G125GM,115 uniquely combines ultra-low RON, true bidirectional analog pass-through, and IOFF-enabled power sequencing-making it the sole option for high-fidelity, low-latency, multi-rail bus isolation in compact industrial designs.

FAQ
What is the maximum recommended operating frequency for analog signal switching?
The device supports analog signals up to 263 MHz (–3 dB point) when VCC = 3.3 V and RL = 50 Ω. This bandwidth is validated per Figure 11 test circuit and applies to small-signal AC coupling. For digital signals, the 0.16 ns typical propagation delay supports data rates exceeding 1 Gbps with adequate setup/hold margins.
Can the 74CBTLV1G125GM,115 be used with 1.8 V logic levels?
No. The minimum supply voltage is 2.3 V, and VIH is specified as 1.7 V (min) only at VCC = 2.3 V to 2.7 V. At 1.8 V supply, the device will not meet guaranteed switching thresholds or RON specifications. Use 74LVC1G125 or similar 1.65–1.95 V logic family for true 1.8 V operation.
Is external pull-up required on the OE pin?
Yes - to guarantee high-impedance OFF-state during power-up/power-down, OE must be tied to VCC via a pull-up resistor. The datasheet specifies current-sinking capability determines minimum resistance value; 10 kΩ is typical for 3.3 V systems, ensuring <1 μA leakage while maintaining fast disable timing.
Does the n.c. pin (Pin 4 in SOT886) require PCB pad connection?
No. Pin 4 is internally unconnected and must remain floating on the PCB. No copper pour, solder mask opening, or thermal relief should be applied. Leaving it unconnected avoids unintended parasitic coupling and complies with Nexperia's assembly recommendations for SOT886 packages.
