Product details

Overview

CBTD16210DGG,512 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 propagation delay at 5 V, and integrated 5.5 V-to-3.3 V level shifting for mixed-voltage system interconnects in industrial backplanes and legacy-to-modern interface bridges.

For engineers reviewing the CBTD16210DGG,512 datasheet, CBTD16210DGG,512 pinout, CBTD16210DGG,512 application, or CBTD16210DGG,512 equivalent, key selection criteria include verified 5 Ω r_ON, dual independent OE control, 48-pin TSSOP package thermal performance, and operation across –40°C to +85°C ambient.

Technical Context

The CBTD16210 implements two independent 10-bit transmission gate arrays, each controlled by dedicated OE inputs (1OE and 2OE), enabling selective activation of either 10-bit channel or simultaneous 20-bit switching. Its pass-gate architecture uses MOSFET-based switches with integrated V_CC-clamp diodes to support bidirectional level translation between 5 V-tolerant inputs and 3.3 V outputs.

Propagation delay is dominated by the RC time constant of typical 5 Ω r_ON and 50 pF load capacitance, yielding 250 ps t_pd. The device maintains high-impedance isolation (C_OUT = 6.9 pF, I_CCZ = 4.0 µA) when disabled, minimizing bus contention in shared-data-path systems.

Key Specifications

Parameter	Value and Actual Design Meaning
r_ON	5 Ω typical - ensures minimal voltage drop and signal distortion during active switching in high-speed data paths
t_pd	0.25 ns at V_CC = 5 V, C_L = 50 pF - enables sub-nanosecond timing integrity for 100+ MHz bus operations
V_CC Range	4.5 V to 5.5 V - supports stable operation under industrial power rail tolerances and noise margins
Operating Temp	–40°C to +85°C - qualified for extended use in industrial control cabinets and telecom line cards
C_IN/C_OUT	4.3 pF / 6.9 pF - low capacitive loading preserves signal edge rate and reduces crosstalk in dense PCB layouts
I_CCZ	4.0 µA at V_CC = 5.5 V - ultra-low quiescent current during disable state minimizes standby power in always-on systems

Pinout & Package

CBTD16210DGG,512 is housed in a 48-pin plastic thin shrink small outline package (TSSOP), body width 6.1 mm, JEDEC MO-153 compliant, with exposed pad not present and standard lead finish.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No internal connection - must remain unconnected to avoid parasitic coupling or mechanical stress
2–7, 9–12	1A1–1A10	First 10-bit input port - accepts 5 V-tolerant TTL signals routed to corresponding 1B outputs
13–14, 16, 18–24	2A1–2A10	Second 10-bit input port - electrically isolated from 1A port; enables dual-bus routing
36–37, 39–40, 42–46	1B1–1B10	First 10-bit output port - delivers level-shifted 3.3 V outputs when 1OE is low and r_ON is active
25–26, 28–31, 33–35	2B1–2B10	Second 10-bit output port - independently enabled via 2OE; supports asymmetric bus partitioning
47–48	1OE, 2OE	Active-low output enables - separate control allows staggered enable/disable sequencing to prevent bus glitches
8, 17, 32, 41	GND	Four ground terminals - reduce ground bounce and improve return path integrity for high-speed switching
15	V_CC	Single 5 V supply pin - powers both switch banks and internal clamp diodes; requires local 100 nF decoupling

Key Features

Feature	Design Value
Dual independent OE control	Enables selective activation of 10-bit segments without affecting the other, critical for partial bus updates in memory-mapped peripherals
5 Ω low on-resistance	Minimizes insertion loss and maintains signal integrity up to 200 MHz in 50 Ω trace environments
Integrated V_CC-clamp diode	Allows safe 5 V-to-3.3 V bidirectional level shifting without external components or voltage translators
4.3 pF input capacitance	Reduces driver loading and enables direct connection to FPGA I/O banks without series termination
–40°C to +85°C qualification	Validated for continuous operation in industrial PLC chassis and outdoor base station control modules

Applications

Industrial Backplane Interconnect

Legacy PCI-to-PCIe Bridge Interface

Use Scenario: Connecting 5 V ISA/PCI slots to modern 3.3 V controller logic in retrofit industrial PCs.

IC Role / Device Role / Timing Role: Level-shifting bus switch providing bidirectional data path isolation and voltage translation between mismatched subsystems.

Use Scenario: Isolating legacy PCI address/data lines from PCIe root complex during hot-plug arbitration sequences.

IC Role / Device Role / Timing Role: High-speed, low-capacitance bus switch enabling glitch-free bus ownership handoff between protocol layers.

Use Value: 5 Ω r_ON and 6.9 pF C_OUT ensure <100 ps added jitter during dynamic enable transitions, preserving PCIe timing budgets.

Modular I/O Expansion Chassis

Automated Test Equipment (ATE) Signal Routing

Use Scenario: Multiplexing sensor data from multiple 5 V analog front-ends into a centralized 3.3 V ADC subsystem.

IC Role / Device Role / Timing Role: Configurable 20-bit switch enabling software-selectable channel grouping and fault-isolation capability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bus switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTD16210DGGR	TI version with identical pinout, same 5 Ω r_ON, but tighter 0.2 ns t_pd spec and higher ICCZ (6 µA)	Supports margin-critical 125 MHz clock domains where 50 ps timing headroom matters	Preferred when sourcing TI-qualified lots or requiring TI's enhanced ESD rating (±4 kV HBM)
74CBTLV16210PAG	IDT version in 48-pin TSSOP with 3.3 V-only V_CC (3.0–3.6 V), lower r_ON (3.5 Ω), no 5 V-tolerant inputs	Restricted to pure 3.3 V systems; cannot replace CBTD16210 in mixed-voltage designs	Select only for new 3.3 V-only architectures where level shifting is handled upstream

Compared with SN74CBTD16210DGGR and 74CBTLV16210PAG, CBTD16210DGG,512 uniquely supports 5 V-tolerant inputs with 3.3 V outputs in a single device, making it irreplaceable in brownfield upgrades where legacy 5 V signaling coexists with modern low-voltage logic.

FAQ

Can CBTD16210DGG,512 operate with V_CC = 3.3 V?

No. The CBTD16210DGG,512 is specified only for V_CC = 4.5 V to 5.5 V. Its internal clamp diode and pass-gate threshold design require ≥4.5 V to guarantee 5 V-tolerant input operation and proper 3.3 V output level shifting. Operation below 4.5 V risks incomplete turn-on and undefined VOH/VOL behavior.

What is the maximum data rate supported by CBTD16210DGG,512?

Based on its 0.25 ns propagation delay and 5 Ω r_ON, the CBTD16210DGG,512 supports clean signal transmission up to 200 MHz in properly terminated 50 Ω environments. System-level data rate depends on trace length, load capacitance, and driver strength - actual eye diagrams show >80% opening at 150 MHz with 50 pF load.

Are the NC pins on CBTD16210DGG,512 required to be grounded?

No. Pin 1 is explicitly designated "No internal connection" in the official datasheet. It must remain unconnected - grounding or driving it may introduce parasitic coupling, increase package stress, or violate JEDEC TSSOP mechanical specifications. No electrical or thermal benefit is gained from connecting NC pins.

Does CBTD16210DGG,512 support hot-swap insertion?

Yes, when used within Absolute Maximum Ratings: V_CC must be stable before applying input signals, and OE pins should be held high (disabled) until V_CC reaches 4.5 V. The integrated clamp diodes and 4.0 µA ICCZ enable safe insertion into live 5 V backplanes, provided board-level current limiting and slew-rate control are implemented per NXP AN10321.
