Product details
Overview
CBT16210DGG,118 from NXP Semiconductors (formerly Philips) is a 20-bit TTL-compatible bus switch with dual 10-bit output-enable control, 5 Ω on-state resistance, 0.25 ns typical propagation delay at 5 V, and operation from –40°C to +85°C. It functions as two independent 10-bit switches or one unified 20-bit switch in high-speed data path isolation and level translation applications.
For engineers reviewing the CBT16210DGG,118 datasheet, CBT16210DGG,118 pinout, CBT16210DGG,118 application, or CBT16210DGG,118 equivalent, key selection criteria include dual OE control timing (tPZH ≤ 5.0 ns), low off-state capacitance (CIO(OFF) = 6.9 pF), high-impedance isolation integrity, and TSSOP-48 package compatibility with dense PCB layouts.
Technical Context
The CBT16210DGG,118 implements a passive FET-based analog switch architecture with no internal logic or level-shifting circuitry - signal paths are direct A-to-B connections controlled solely by OE inputs. Its dual 10-bit structure enables independent enable/disable of two 10-bit data lanes, supporting asymmetric bus gating in memory expansion and multiplexed I/O systems.
It operates strictly within 4.5 V to 5.5 V supply range, with TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), and guarantees sub-5 ns output enable/disable transitions across full temperature range. The device exhibits no DC current consumption in disabled state (ICCZ = 4.0 µA at VCC = 5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance | 5 Ω typical - ensures minimal voltage drop and signal distortion under 30 mA load |
| Propagation delay | 0.25 ns typical (An to Yn, CL = 50 pF) - supports >1 GHz data rate switching |
| Supply voltage range | 4.5 V to 5.5 V - compatible with standard 5 V TTL and mixed-voltage system rails |
| Operating temperature | –40°C to +85°C - qualified for industrial-grade embedded and telecom equipment |
| Off-state capacitance | 6.9 pF - limits crosstalk and loading on adjacent traces in high-density routing |
| Input leakage current | ±1 µA max - preserves signal integrity during hot-swap or partial-power-down states |
| ESD rating | HBM 2000 V, CDM 1000 V - meets industrial handling robustness requirements |
Pinout & Package
CBT16210DGG,118 is housed in a 48-pin plastic thin shrink small outline package (TSSOP), body width 6.1 mm, lead pitch 0.5 mm, compliant with JEDEC MO-153 (SOT362-1). Pin 1 is NC (no internal connection); pins 47–48 are 1OE and 2OE; ground pins are at positions 8, 17, 32, and 41; VCC is at pin 15.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left unconnected or tied to GND per layout guidelines |
| 2–7, 9–12 | 1A1–1A10 | First 10-bit input port - bidirectional when enabled; connects directly to 1B1–1B10 |
| 13–14, 16, 18–24 | 2A1–2A10 | Second 10-bit input port - independent of first port; connects to 2B1–2B10 when 2OE active |
| 36–37, 39–40, 42–46 | 1B1–1B10 | Outputs for first 10-bit switch - high-impedance when 1OE = HIGH |
| 25–26, 28–31, 33–35 | 2B1–2B10 | Outputs for second 10-bit switch - isolated from 1B ports; no internal coupling |
| 47, 48 | 1OE, 2OE | Active-low enables - each controls one 10-bit section; OE HIGH disables associated port |
| 8, 17, 32, 41 | GND | Four dedicated ground terminals - required for low-noise switching and thermal dissipation |
| 15 | VCC | Single positive supply - powers all switch channels; decoupling capacitor mandatory at pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit switching | Enables selective gating of two data buses without inter-port interference or shared timing constraints |
| 5 Ω on-resistance | Maintains signal fidelity for 3.3 V/5 V logic levels up to 64 mA per channel without significant IR drop |
| Sub-nanosecond propagation delay | Preserves timing margins in high-speed parallel interfaces such as legacy PCI, ISA, or custom backplanes |
| TTL-compatible control inputs | Eliminates need for level translators when driven by standard 5 V microcontrollers or CPLDs |
| Low off-state capacitance (6.9 pF) | Reduces capacitive loading on inactive buses, critical for maintaining signal rise/fall times in multi-drop topologies |
Applications
| Memory Expansion Interface | Legacy Peripheral Multiplexing |
|---|---|
Use Scenario: Adding external SRAM or Flash to an MCU with limited address/data pins via time-shared bus access. IC Role / Device Role / Timing Role: Bidirectional bus switch isolating main CPU bus from expansion memory bus; 1OE/2OE sequenced to avoid contention. Use Value: Enables 20-bit wide memory access using only 10-bit physical traces, reducing PCB layer count and routing complexity. | Use Scenario: Sharing a single 8-bit data bus among multiple legacy peripherals (e.g., UART, parallel ADC, keypad controller). IC Role / Device Role / Timing Role: Bus gate controlling which peripheral connects to host processor; OE signals synchronized with chip-select strobes. Use Value: Eliminates need for discrete logic or complex bus arbitration, lowering BOM cost and firmware overhead. |
| Hot-Swappable I/O Module Isolation | Level Translation Between 5 V and 3.3 V Subsystems |
Use Scenario: Isolating field-replaceable I/O modules in industrial PLC backplanes during live insertion/removal. IC Role / Device Role / Timing Role: High-impedance barrier inserted between host backplane and module edge connector; OE asserted before power sequencing. Use Value: Prevents back-driving and latch-up during hot-swap events; 6.9 pF off-capacitance minimizes transient coupling. | Use Scenario: Interfacing a 5 V microcontroller to 3.3 V sensors or communication ICs without dedicated level shifters. IC Role / Device Role / Timing Role: Passive voltage-domain bridge - relies on 3.3 V device tolerating 5 V inputs (if permitted) or clamping via internal diodes. Use Value: Leverages inherent 5 V-tolerant inputs and low Ron to pass signals with <100 mV drop, avoiding active translation latency and power draw. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTD16210PAG | Higher ICCZ (20 µA vs. 4.0 µA), same 5 Ω Ron, identical TSSOP-48 footprint | Requires tighter VCC decoupling due to higher quiescent current; slightly slower tPHZ (max 6.5 ns) | Preferred where TI ecosystem support or extended voltage margin (up to 5.5 V) is prioritized over ultra-low standby current |
| 74LVC16245ADGG | Direction-controlled transceiver (not bidirectional switch); 3-state outputs only; 3.3 V only supply | Cannot replace CBT16210DGG,118 in bidirectional or 5 V environments; requires direction control logic | Only suitable if system uses 3.3 V exclusively and direction is managed externally - not a functional substitute |
Compared with SN74CBTD16210PAG and 74LVC16245ADGG, the CBT16210DGG,118 delivers lower static power (4.0 µA vs. 20 µA), true bidirectional zero-delay switching, and native 5 V operation - making it optimal for industrial backplanes and legacy 5 V system upgrades where power efficiency and signal transparency are critical.

FAQ
What is the maximum operating frequency supported by the CBT16210DGG,118?
The CBT16210DGG,118 does not specify a maximum clock frequency, but its 0.25 ns typical propagation delay and 6.9 pF off-state capacitance enable reliable operation in parallel bus systems running up to 1 GHz effective data rates. Real-world bandwidth depends on trace impedance, load capacitance, and drive strength - the CBT16210DGG,118 itself introduces negligible delay or jitter in properly terminated 50 Ω environments.
Can the CBT16210DGG,118 be used with 3.3 V logic levels?
The CBT16210DGG,118 requires a 4.5 V to 5.5 V VCC supply and is not rated for 3.3 V operation. While its inputs are TTL-compatible (VIH ≥ 2.0 V), the internal switch FETs are optimized for 5 V rail operation. Using CBT16210DGG,118 with 3.3 V VCC risks excessive on-resistance and timing violations - NXP recommends the 74LVC series for 3.3 V-only systems.
Is the CBT16210DGG,118 pin-compatible with the CBT16210DL?
Yes, the CBT16210DGG,118 (TSSOP-48) and CBT16210DL (SSOP-48) share identical pin numbering, signal assignment, and electrical specifications. Both use SOT362-1 and SOT370-1 footprints respectively, but their mechanical dimensions differ - CBT16210DGG,118 has narrower body width (6.1 mm vs. 7.5 mm), so PCB land patterns are not interchangeable without layout revision.
Does the CBT16210DGG,118 support hot-plug operation?
The CBT16210DGG,118 supports hot-plug operation when OE is held HIGH (disabled) during insertion, preventing back-driving. Its HBM 2000 V and CDM 1000 V ESD ratings meet industrial handling requirements, and the 4.0 µA ICCZ ensures minimal leakage current during partial power-up. For full hot-swap compliance, external current-limiting and sequencing circuits remain necessary - the CBT16210DGG,118 itself provides the isolation foundation.
What is the function of the NC pin (pin 1) on the CBT16210DGG,118?
Pin 1 of the CBT16210DGG,118 is designated NC (No internal connection) and must not be connected to any signal or power net. NXP specifies that this pin is electrically floating and unbonded; connecting it may cause unpredictable behavior or increased leakage. Layout best practice is to leave pin 1 unmasked or tie it to GND only if required for mechanical stability - never to VCC or a control signal.
