Product details
Overview
CBT16210DL,118 from NXP Semiconductors (formerly Philips) is a 20-bit TTL-compatible bus switch organized as dual 10-bit sections with independent output-enable controls, 5 Ω on-state resistance, 0.25 ns propagation delay (CL = 50 pF), and operation from –40°C to +85°C. It enables high-speed bidirectional data routing in memory expansion, CPU-to-peripheral interconnects, and logic-level translation circuits.
For engineers reviewing the CBT16210DL,118 datasheet, CBT16210DL,118 pinout, CBT16210DL,118 application, or CBT16210DL,118 equivalent, key selection criteria include dual-section enable control timing (tPZH = 3.3 ns typ), low off-state capacitance (6.9 pF), supply current under quiescent conditions (4.0 µA), and SSOP-48 package compatibility with high-density PCB layouts.
Technical Context
The CBT16210DL,118 implements two independent 10-bit analog bus switches using NMOS transmission gates, each controlled by dedicated OE inputs (1OE and 2OE). Its TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V) allow direct interfacing with legacy 5 V logic families without level-shifting circuitry.
Each switch section exhibits matched on-resistance (5–7 Ω at VCC = 4.5 V) and symmetrical propagation delay (tPLH/tPHL = 0.25 ns typ), supporting bidirectional signal integrity in both active and high-impedance states. The device operates only at 4.5–5.5 V supply, with no internal voltage regulation or ESD protection beyond specified CDM (1000 V) and HBM (2000 V) ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance | 5–7 Ω at VCC = 4.5 V; ensures minimal voltage drop and signal distortion during active switching |
| Propagation delay | 0.25 ns typical (An to Yn, CL = 50 pF); supports >1 GHz data rates in short trace applications |
| Supply voltage range | 4.5–5.5 V; compatible with standard 5 V TTL/CMOS systems, not 3.3 V tolerant |
| Quiescent supply current | 4.0 µA (outputs disabled, VCC = 5.5 V); enables ultra-low static power in standby mode |
| Off-state capacitance | 6.9 pF per port; minimizes crosstalk and loading on adjacent high-speed traces |
| Operating temperature | –40°C to +85°C; validated for industrial-grade embedded control and instrumentation environments |
| Input capacitance | 4.3 pF; reduces drive burden on upstream logic drivers and improves fan-out capability |
Pinout & Package
CBT16210DL,118 is housed in a 48-pin plastic shrink small outline package (SSOP), body width 7.5 mm, drawing SOT370-1. Pin 1 is NC (no internal connection); pins 8, 17, 32, and 41 are GND; pin 15 is VCC; pins 47 and 48 serve as 1OE and 2OE respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection; must remain unconnected to avoid mechanical stress or unintended coupling |
| 2–12, 13–24 | 1A1–1A10, 2A1–2A10 | Input ports for dual 10-bit switch sections; routed to corresponding B-side outputs when OE is asserted |
| 36–46, 25–35 | 1B1–1B10, 2B1–2B10 | Output ports; present high-impedance state when associated OE is high, otherwise mirror A-side signals |
| 47, 48 | 1OE, 2OE | Active-low enable inputs; independently activate each 10-bit section; tied low to enable, high to isolate |
| 8, 17, 32, 41 | GND | Four dedicated ground terminals; reduce ground bounce and improve noise immunity in high-speed switching |
| 15 | VCC | Single 4.5–5.5 V supply input; decoupling capacitor required within 1 cm for stable switching performance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit switching | Enables selective isolation of two data paths (e.g., separate address/data buses) without shared control latency |
| 5 Ω low on-resistance | Minimizes insertion loss and maintains signal edge fidelity in 50 Ω–100 Ω system impedance environments |
| TTL-compatible control inputs | Accepts standard 5 V logic thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), eliminating need for external level translators |
| 6.9 pF off-state capacitance | Reduces capacitive loading on inactive bus segments, preserving signal integrity during partial-bus activation |
| SSOP-48 package (SOT370-1) | Supports automated assembly and provides thermal/mechanical stability for industrial PCBs with 0.5 mm pitch |
Applications
| Memory Expansion Interface | CPU-to-Peripheral Multiplexing |
|---|---|
|
Use Scenario: Expanding 16-bit microcontroller address/data bus to access multiple SRAM or Flash devices via time-multiplexed addressing. IC Role / Device Role / Timing Role: Bidirectional bus switch isolating memory banks; enables dynamic reconfiguration without bus contention. Use Value: Dual OE control allows staggered enable timing (tPZH = 3.3 ns typ), preventing simultaneous access conflicts during bank switching. |
Use Scenario: Sharing a single 8-bit parallel interface between UART, SPI controller, and LCD driver on an MCU with limited GPIO. IC Role / Device Role / Timing Role: Logic-level-transparent signal router; passes TTL-level signals with sub-nanosecond delay and zero logic inversion. Use Value: 0.25 ns propagation delay preserves setup/hold timing margins for peripherals operating up to 200 MHz clock domains. |
| Legacy System Bus Isolation | Logic-Level Translation Bridge |
|
Use Scenario: Isolating fault-prone I/O modules (e.g., relay drivers) from main system bus in industrial PLC backplanes. IC Role / Device Role / Timing Role: High-impedance barrier during module hot-swap or failure; prevents back-driving into healthy subsystems. Use Value: 6.9 pF off-state capacitance limits coupling-induced glitches, reducing false triggers in safety-critical control loops. |
Use Scenario: Interfacing 5 V TTL sensors to 3.3 V FPGA I/O banks where level shifters introduce unacceptable delay or skew. IC Role / Device Role / Timing Role: Passive voltage-domain bridge; relies on FPGA's 5 V-tolerant inputs and CBT16210's low Ron to limit voltage drop. Use Value: 5 Ω on-resistance ensures <100 mV drop at 20 mA sink/source, maintaining valid logic levels across mixed-voltage boundaries. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTD16210DGGR | Higher ICCZ (10 µA vs. 4.0 µA); same 5 Ω Ron, but tighter tPLH/tPHL matching (0.2 ns max) | Designed for TI's 1.8–5.5 V flexible supply range; supports mixed-voltage systems where CBT16210DL,118 does not | Select when operating below 4.5 V or requiring lower timing skew across all 20 bits |
| 74LVC16245ADGG | Bidirectional transceiver (not passive switch); includes direction control and 24 mA drive strength; Ron > 20 Ω | Provides active buffering and level shifting; unsuitable for transparent pass-through or ultra-low-delay routing | Select only when bus driving capability or direction control is required-otherwise introduces unnecessary complexity and delay |
Compared with SN74CBTD16210DGGR and 74LVC16245ADGG, CBT16210DL,118 delivers lowest static current and purest signal transparency for fixed 5 V systems, while avoiding the timing uncertainty of active transceivers or the higher leakage of wider-supply alternatives.

FAQ
Is CBT16210DL,118 compatible with 3.3 V logic systems?
No. CBT16210DL,118 requires a 4.5–5.5 V supply and has TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), but its outputs swing rail-to-rail at VCC. Driving it from 3.3 V logic may result in marginal VIH margin and undefined switching behavior. It is not rated for 3.3 V operation.
Can both 10-bit sections be used simultaneously as a single 20-bit switch?
Yes. When both 1OE and 2OE are driven low, the device functions as a unified 20-bit bus switch with all A-to-B paths enabled. The pinout supports this configuration directly-no external wiring changes are needed beyond tying both OE pins to GND.
What is the maximum capacitive load the CBT16210DL,118 can drive reliably?
The AC characteristics specify CL = 50 pF for propagation delay testing. While the device can drive higher loads, exceeding 50 pF increases tpd nonlinearly due to RC time constant effects (Ron × CL). For reliable <1 ns delay, keep total load ≤50 pF including trace and probe capacitance.
Does CBT16210DL,118 support hot-swap or live-insertion?
No. The device lacks power-on reset, bus-hold, or Ioff protection. Applying signal voltages before VCC stabilization risks latch-up or excessive ICCZ. It must be powered and stabilized before enabling OE or applying input signals to ensure safe operation.
