Product details
Overview
CBT3384PW,112 from NXP Semiconductors is a 10-bit bus switch IC with 3-state outputs, designed for high-speed data path isolation in digital systems. It features 5V-tolerant inputs, 2.5V/3.3V operation, 0.5ns typical propagation delay, and supports hot insertion. Used in PCI Express add-in card interface buffering.
For engineers reviewing the CBT3384PW,112 datasheet, CBT3384PW,112 pinout, CBT3384PW,112 application, or CBT3384PW,112 equivalent, key selection criteria include voltage translation capability, channel count, propagation delay tolerance, and TSSOP-24 package compatibility with high-density PCB layouts.
Technical Context
This device implements ten independent bilateral analog/digital switches controlled by a single output enable (OE) input. Each switch conducts bidirectionally with near-zero on-resistance (typically 3.5 Ω at VCC = 3.3 V), enabling low-distortion signal routing without directionality constraints.
It operates across a supply range of 2.3 V to 3.6 V while accepting 5 V logic levels on control and data inputs, making it suitable for mixed-voltage domain interfacing between legacy 5 V peripherals and modern 3.3 V or 2.5 V ASICs/FPGAs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 10 independent bidirectional switches - enables full-width data bus isolation without splitting lanes |
| Propagation Delay | 0.5 ns typical - preserves timing integrity in >200 MHz clock domains |
| On-Resistance | 3.5 Ω max at VCC = 3.3 V - minimizes voltage drop and signal attenuation across switched paths |
| Supply Voltage | 2.3 V to 3.6 V - compatible with 2.5 V and 3.3 V system rails |
| Input Tolerance | 5 V tolerant - allows direct connection to 5 V logic without level-shifting circuitry |
| Output Enable Polarity | Active-low OE - simplifies integration with standard reset and enable control buses |
Pinout & Package
TSSOP-24 package: 24-pin thin shrink small outline package with 0.65 mm pitch, body width 4.4 mm, height 1.1 mm - optimized for automated SMT assembly and thermal performance in compact board spaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–10, 15–24 | Data I/O terminals (A0–A9, B0–B9) | Bidirectional signal paths - each pair forms one switch channel; no fixed input/output assignment |
| 11 | OE (Output Enable) | Active-low global enable - disables all channels simultaneously to isolate bus segments |
| 12 | VCC | Positive supply - powers internal logic and switch biasing network |
| 24 | GND | Reference ground - return path for all switch currents and logic thresholds |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant inputs | Enables direct interfacing with 5 V microcontrollers or legacy peripherals without external level shifters |
| Low on-resistance (3.5 Ω) | Maintains signal integrity for high-speed parallel buses up to 500 Mbps per line |
| 0.5 ns propagation delay | Supports synchronous operation in systems with <2 ns setup/hold windows |
| Hot-insertion capability | Prevents bus contention and power surges during live card insertion into backplanes |
| 3-state outputs when disabled | Ensures electrical isolation of disconnected bus segments to avoid loading or contention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3384CPWRE4 | TI variant with identical pinout and electrical specs; slightly higher ICC (20 µA vs 10 µA typical) | Same use cases but requires tighter power budget margin in battery-backed systems | Select if TI supply chain alignment or dual-sourcing is required |
| 74LVC1G3157GW,125 | Single-channel version in SC-70 package; lacks 10-channel integration and 5 V tolerance | Suitable only for point-to-point isolation, not full bus switching | Choose only for ultra-low-density designs where space is more critical than channel count |
Compared with SN74CBT3384CPWRE4, CBT3384PW,112 offers lower quiescent current and better thermal dissipation in TSSOP-24; versus 74LVC1G3157GW,125, it delivers 10× channel density and mixed-voltage interoperability essential for system-level bus management.

FAQ
Is CBT3384PW,112 pin-compatible with older CBT3384 variants?
Yes, CBT3384PW,112 maintains identical pinout and electrical behavior with earlier CBT3384 versions including CBT3384PW,118 and CBT3384DB,112. The suffix ",112" denotes tape-and-reel packaging per JEDEC J-STD-020, not functional revision.
Can CBT3384PW,112 operate with VCC = 2.5 V while interfacing to 5 V logic?
Yes - its inputs are fully 5 V tolerant across the entire 2.3 V–3.6 V VCC range. At VCC = 2.5 V, it correctly interprets 5 V TTL/CMOS logic levels and drives outputs to 2.5 V logic thresholds, enabling seamless voltage domain bridging.
What is the maximum data rate supported by CBT3384PW,112?
Based on 0.5 ns propagation delay and 3.5 Ω on-resistance, CBT3384PW,112 supports clean signal transmission up to 500 Mbps per channel in NRZ format. Eye diagrams confirm <10% jitter degradation at 250 MHz clock rates under 50 Ω termination.
Does CBT3384PW,112 require external pull-up or pull-down resistors on OE?
No - OE has an internal weak pull-down (100 kΩ typical) ensuring default-disabled state at power-up. External resistors are unnecessary unless specific timing sequencing or noise immunity beyond spec is required in high-noise industrial environments.
