Product details
Overview
74CBTLV3257D,118 from Nexperia is a quad 1-of-2 high-speed analog multiplexer/demultiplexer in SO16 package, operating from 2.3 V to 3.6 V supply, featuring 5 Ω typical ON-resistance, <0.25 ns propagation delay, and rail-to-rail signal switching - used for low-distortion data path routing in DDR memory interfaces and FPGA I/O expansion.
For engineers reviewing the 74CBTLV3257D,118 datasheet, 74CBTLV3257D,118 pinout, 74CBTLV3257D,118 application, or 74CBTLV3257D,118 equivalent, key selection criteria include guaranteed 125 °C operation, IOFF-enabled partial power-down capability, Schmitt-trigger control inputs for noise immunity, and verified 398 MHz -3 dB bandwidth at 3.3 V.
Technical Context
This device implements four independent bidirectional analog switches, each controlled by a shared select (S) input and global output enable (OE) input. Switching is governed by CMOS transmission gate architecture with matched P/N channel drive, enabling rail-to-rail voltage handling across the full 2.3–3.6 V VCC range.
Its IOFF circuitry actively disables all switches when VCC = 0 V, blocking backflow current up to ±50 μA, while Schmitt-triggered S and OE inputs tolerate slow edges (≤200 ns/V) without chatter - critical for mixed-signal board-level timing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - supports modern low-voltage logic domains including 2.5 V and 3.3 V systems without level shifters. |
| ON Resistance | Typ. 4.0–7.0 Ω at VCC = 3.3 V - minimizes insertion loss and signal distortion in high-speed digital and analog signal paths. |
| Propagation Delay | Typ. 3.2 ns at VCC = 3.3 V - enables sub-300 ps edge-aligned switching suitable for DDR2/DDR3 clock/data routing. |
| -3 dB Bandwidth | 398 MHz at VCC = 3.3 V, RL = 50 Ω - preserves signal integrity for video, USB 1.1, and low-speed serial links. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor drives. |
| IOFF Leakage | ±50 μA max at VCC = 0 V - prevents damaging back-current during hot-swap or staggered power sequencing. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - withstands handling and board assembly without external protection. |
Pinout & Package
74CBTLV3257D,118 uses the SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads and pin 1 index in lower-left corner below marking code.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S (Select) | Common control input selecting B1 (LOW) or B2 (HIGH) path for all four channels. |
| 2,5,11,14 | 1B1–4B1 | First bidirectional I/O port per channel; connects to A when S = LOW. |
| 3,6,10,13 | 1B2–4B2 | Second bidirectional I/O port per channel; connects to A when S = HIGH. |
| 4,7,9,12 | 1A–4A | Common bidirectional I/O terminal per channel; routes to selected B port. |
| 8 | GND | Reference ground plane connection; must be low-impedance for noise suppression. |
| 15 | OE (Output Enable) | Active-LOW global enable; HIGH forces all switches into high-Z OFF-state regardless of S. |
| 16 | VCC | Primary power supply; decoupling capacitor required within 1 cm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full 0 V to VCC signal swing on all I/O ports - eliminates clipping in mixed-signal sensor or audio paths. |
| IOFF partial power-down | Blocks current flow between powered and unpowered system domains - essential for PCIe hot-plug and modular backplane designs. |
| Schmitt-trigger control inputs | Enables reliable switching with slow-rising/falling control signals (e.g., from microcontroller GPIO) without oscillation. |
| Low ON-state capacitance | CS(ON) = 14.3 pF - reduces loading on high-frequency source drivers and maintains signal rise/fall times. |
| JEDEC-compliant voltage specs | Meets JESD8-5 (2.3–2.7 V) and JESD8-B/JESD36 (2.7–3.6 V) - ensures interoperability across vendor logic families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV3257PWR | TI version in TSSOP16; identical electrical specs but higher typical ON-resistance (7.0 Ω vs. 4.0 Ω at 3.3 V). | Same functional pinout but lacks IOFF specification - unsuitable for hot-swap or partial power-down systems. | Select only if TI supply chain preference overrides need for guaranteed zero-power isolation. |
| 74LVC1G3157GW | Single-channel variant in SC-70; 6.5 Ω ON-resistance, 3.3 V only, no IOFF, rated to +85 °C only. | Requires four units to match quad functionality; increases board area and routing complexity. | Use only for space-constrained prototypes where temperature range and power sequencing are non-critical. |
Compared with SN74CBTLV3257PWR and 74LVC1G3157GW, the 74CBTLV3257D,118 uniquely delivers quad-channel integration, guaranteed 125 °C operation, and certified IOFF behavior - making it the sole choice for automotive and industrial hot-swap architectures.

FAQ
What is the maximum allowable signal voltage swing on the A/B ports?
The 74CBTLV3257D,118 supports rail-to-rail analog switching: signals may swing from 0 V to VCC (2.3–3.6 V) on all A and B terminals without damage or performance degradation. This is confirmed in Section 2 ("Rail to rail switching on data I/O ports") and Table 5 limiting values (VSW = –0.5 V to VCC + 0.5 V).
Does the device require external pull-up resistors on OE or S inputs?
OE must be pulled up to VCC via an external resistor during power-up/down to guarantee high-impedance OFF-state; minimum resistance depends on driver sink capability. S does not require pull-up, but Schmitt-trigger action allows direct MCU GPIO connection without external biasing.
Can this part be used in 1.8 V systems?
No - the absolute minimum supply voltage is 2.3 V per Table 6, and VIH/VIL thresholds are defined only down to 2.3 V. Operation below 2.3 V violates recommended conditions and risks undefined switching behavior or increased ON-resistance.
How is thermal performance affected by package choice?
The SO16 (SOT109-1) package has 500 mW total power dissipation at ≤110 °C, derating linearly above that. DHVQFN16 (SOT763-1) offers superior thermal resistance (11.2 mW/K derating above 106 °C), enabling higher sustained current in compact layouts - confirmed in Table 5 footnotes.
