Product details

Overview

CBTD16210DGG,112 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 integrated level-shifting diode enabling 5.5 V-to-3.3 V bidirectional voltage translation in high-speed data buses.

For engineers reviewing the CBTD16210DGG,112 datasheet, CBTD16210DGG,112 pinout, CBTD16210DGG,112 application, or CBTD16210DGG,112 equivalent, key selection criteria include verified 48-pin TSSOP package mapping, dual independent OE control for partial bus isolation, sub-nanosecond timing performance under 50 pF load, and guaranteed operation across –40°C to +85°C industrial temperature range.

Technical Context

The CBTD16210 implements two independent 10-bit analog bus switches using low-resistance MOS pass-gates, each controlled by dedicated OE inputs. Its internal diode-to-V_CC structure enables asymmetric voltage translation: 5 V-tolerant inputs driving 3.3 V-compatible outputs without external components.

Propagation delay is dominated by the RC time constant of r_on (5–7 Ω) and load capacitance (50 pF), yielding 250 ps typical t_pd. Output enable/disable times (t_PZH, t_PHZ, t_PZL, t_PLZ) are specified down to 1.0 ns, supporting high-throughput address/data bus switching in legacy 5 V/3.3 V mixed-voltage systems.

Key Specifications

Parameter	Value and Actual Design Meaning
On-state resistance	5–7 Ω at V_CC = 4.5 V; ensures minimal signal attenuation and voltage drop across switched paths
Propagation delay	0.25 ns typical (t_PLH/t_PHL, CL = 50 pF); supports >1 GHz effective bus toggle rates
Supply voltage range	4.5–5.5 V; compatible with standard 5 V logic rails while enabling 3.3 V output level shifting
Operating temperature	–40°C to +85°C; qualified for industrial-grade embedded and telecom infrastructure applications
Input capacitance	4.3 pF; reduces loading on upstream drivers and preserves signal integrity in dense PCB layouts
Output capacitance	6.9 pF (outputs disabled); minimizes crosstalk and dynamic power consumption during high-impedance states
Quiescent supply current	1.5 mA at V_CC = 5.5 V; enables low-static-power operation in always-on bus interfaces

Pinout & Package

CBTD16210DGG,112 is housed in a 48-pin plastic thin shrink small outline package (TSSOP), body width 6.1 mm, per SOT362-1 drawing. Pin 1 is NC (no internal connection); pins 47–48 are OE inputs; ground pins are at positions 8, 17, 32, and 41; V_CC is at pin 15.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No internal connection; must be left unconnected or tied to GND for mechanical stability
2–7, 9–12	1A1–1A10	First 10-bit input port; accepts 5 V-tolerant TTL-level signals for level-shifted routing to 1B outputs
13–14, 16, 18–24	2A1–2A10	Second 10-bit input port; electrically isolated from 1A but shares same V_CC and GND
36–37, 39–40, 42–46	1B1–1B10	First 10-bit output port; delivers 3.3 V-compatible signals when 1OE is low and switch is enabled
25–31, 33–35	2B1–2B10	Second 10-bit output port; independently controllable via 2OE; supports split-bus or full 20-bit operation
47, 48	1OE, 2OE	Active-low output enables; each controls one 10-bit channel; allows selective bus segmentation
8, 17, 32, 41	GND	Four dedicated ground terminals; reduce ground bounce and improve noise immunity in high-speed switching
15	V_CC	Single 4.5–5.5 V supply; powers both switch channels and internal level-shifting diodes

Key Features

Feature	Design Value
Dual independent 10-bit bus switches	Enables flexible partitioning: use as two isolated 10-bit paths or one consolidated 20-bit path via shared OE control
Integrated level-shifting diode	Permits direct 5 V-to-3.3 V translation without external resistors or clamps, reducing BOM count and layout area
Sub-nanosecond propagation delay	0.25 ns typical t_pd ensures timing-critical applications (e.g., memory address latching) meet setup/hold margins
TTL-compatible control inputs	VIH = 2.0 V min, VIL = 0.8 V max; interoperable with legacy 5 V microcontrollers and FPGAs without level translators
Low on-state resistance	5–7 Ω r_on limits voltage drop to <150 mV at 30 mA, preserving signal swing and noise margin in loaded buses

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTD16210DGGR	Same pinout and function; TI version with identical 5 Ω r_on, 0.25 ns t_pd, and TSSOP-48 package; slightly higher ICCZ (6 µA vs 4 µA)	Valid drop-in replacement in TI-design ecosystems; requires validation of thermal derating above 70°C due to differing junction-to-ambient θ_JA	Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation
74CBTLV16210PAG	Lower V_CC range (2.3–3.6 V); no integrated level-shifting diode; 3.5 Ω r_on; designed for 3.3 V-only systems	Not suitable for 5 V-to-3.3 V translation; requires external level shifters if interfacing 5 V logic; better for pure 3.3 V high-speed backplanes	Choose only for new 3.3 V-native designs where lower supply voltage and reduced power are prioritized over mixed-voltage support

Compared with SN74CBTD16210DGGR and 74CBTLV16210PAG, CBTD16210DGG,112 uniquely combines 5 V-tolerant inputs, integrated level-shifting, and industrial temperature rating in a single TSSOP-48 package-making it the sole option for retrofitting legacy 5 V systems with 3.3 V peripherals without redesigning voltage translation circuitry.

FAQ

What is the maximum continuous current per switched channel?

The CBTD16210DGG,112 supports up to 128 mA DC output current in the low state per output pin, as specified in Absolute Maximum Ratings. However, for reliable operation with ≤7 Ω r_on, sustained current should be limited to 30 mA to maintain <210 mV voltage drop and avoid thermal derating above +70°C ambient.

Can CBTD16210DGG,112 operate with 3.3 V supply instead of 5 V?

No. The device requires V_CC between 4.5 V and 5.5 V per Recommended Operating Conditions. Using 3.3 V violates minimum supply specification and disables the internal level-shifting diode functionality, resulting in undefined output behavior and potential damage to downstream 3.3 V receivers.

How does the integrated diode enable 5 V-to-3.3 V level shifting?

The diode connects from each input pin to V_CC, clamping input voltages to V_CC + 0.7 V. When V_CC = 5 V and a 5 V input is applied, the diode conducts, limiting the internal node voltage to ~5.7 V. The pass-gate then delivers a 3.3 V-compatible output swing referenced to the 3.3 V domain's ground.

Is there any risk of bus contention when both OE inputs are active simultaneously?

No. With both 1OE and 2OE low, both 10-bit channels conduct independently-there is no electrical coupling between 1A/1B and 2A/2B paths. Contention only occurs if external circuitry connects overlapping signal domains; the device itself enforces strict channel isolation even with concurrent OE activation.
