Product details
Overview
CBTD16210DL,112 from NXP Semiconductors (formerly Philips) is a 20-bit TTL-compatible bus switch with dual 10-bit output-enable control, designed for bidirectional 5.5 V ↔ 3.3 V level shifting. It features 5 Ω typical on-state resistance, 0.25 ns propagation delay (CL = 50 pF), and operates from –40°C to +85°C in a 48-pin SSOP package. Used in high-speed memory/data bus isolation between mixed-voltage subsystems.
For engineers reviewing the CBTD16210DL,112 datasheet, CBTD16210DL,112 pinout, CBTD16210DL,112 application, or CBTD16210DL,112 equivalent, key selection criteria include verified 5 Ω Ron, dual independent OE control, 50 pF load-driven timing, integrated input diode for level translation, and industrial temperature support - all critical for legacy-to-modern voltage domain bridging.
Technical Context
The CBTD16210 implements two independent 10-bit transmission-gate bus switches, each controlled by a dedicated OE input (1OE/2OE). Its pass-transistor architecture enables true bidirectional signal flow with minimal voltage drop and no internal latching or logic inversion.
Level shifting is achieved via integrated clamp diodes from inputs to VCC, allowing 5 V-tolerant inputs to drive 3.3 V outputs safely. The device draws only 4.0 µA quiescent current when disabled and maintains <7 Ω max on-resistance across full operating temperature and supply range (4.5–5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance (Ron) | 5 Ω typical; ensures <0.15 V drop at 30 mA, preserving signal integrity in high-speed buses |
| Propagation delay (tPLH/tPHL) | 0.25 ns @ CL = 50 pF, VCC = 5 V; supports >1 GHz data rates in short traces |
| Supply voltage range | 4.5 V to 5.5 V; compatible with standard 5 V logic rails while enabling 3.3 V interface |
| Operating temperature | –40°C to +85°C; qualified for industrial embedded and telecom infrastructure use |
| Input capacitance (CIN) | 4.3 pF; minimizes loading on driving source, critical for fan-out-limited TTL systems |
| Output capacitance (COUT) | 6.9 pF (outputs disabled); reduces crosstalk and improves signal settling in dense PCB layouts |
| Quiescent supply current (ICCZ) | 4.0 µA @ VCC = 5.5 V; enables low-power standby in always-on bus architectures |
Pinout & Package
CBTD16210DL,112 is housed in a 48-pin plastic shrink small outline package (SSOP), type SOT370-1, 7.5 mm body width, with 0.5 mm lead pitch. Pin 1 is NC (no internal connection); pins 8, 17, 32, and 41 are GND; pin 15 is VCC; pins 47–48 are 1OE and 2OE; ports are grouped as 1A1–1A10 / 1B1–1B10 and 2A1–2A10 / 2B1–2B10.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection; must be left unconnected or tied to GND per layout best practice |
| 2–7, 9–12 | 1A1–1A10 | First 10-bit input port; accepts 5 V-tolerant TTL signals for level-shifted output to 1B |
| 36–40, 42–46 | 1B1–1B10 | First 10-bit output port; delivers 3.3 V-compatible signals when 1OE = L |
| 13–14, 16, 18–24 | 2A1–2A10 | Second 10-bit input port; electrically isolated from 1A but shares same VCC/GND |
| 25–31, 33–35 | 2B1–2B10 | Second 10-bit output port; independently enabled by 2OE, supporting split-bus configurations |
| 47, 48 | 1OE, 2OE | Active-low enable inputs; each controls one 10-bit channel, enabling asymmetric bus gating |
| 8, 17, 32, 41 | GND | Four dedicated ground pins; reduce ground bounce and improve noise immunity in high-speed switching |
| 15 | VCC | Single 4.5–5.5 V supply; powers both switch channels and internal clamp diodes |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit switching | Enables selective isolation of two data lanes (e.g., address vs. data) without shared control timing |
| 5 Ω typical Ron | Minimizes insertion loss and skew across 20-bit parallel paths, preserving setup/hold margins |
| Integrated input clamp diodes | Allows safe 5 V input operation into 3.3 V system without external protection components |
| 0.25 ns propagation delay | Supports sub-nanosecond timing budgets in high-frequency backplane and memory interface designs |
| 4.0 µA ICCZ (disabled) | Reduces static power in idle states, critical for energy-constrained industrial controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT16210DGGR | TI part; identical 20-bit dual-OE architecture, 5 Ω Ron, same SSOP-48 package, but specified for 4.5–5.5 V only (no 5.5 V absolute max) | Same industrial temperature range; lacks integrated input clamp diodes - requires external protection for 5 V→3.3 V translation | Select if sourcing TI-qualified supply chain is required and external clamping is acceptable |
| 74CBTLV16210PAG | IDT part; 3.3 V only supply (2.3–3.6 V), lower Ron (~3 Ω), but not 5 V-tolerant - cannot replace directly in mixed-voltage roles | Designed for 3.3 V-only systems; unsuitable for 5 V input domains without level-shifting front-end | Choose only for pure 3.3 V bus isolation where higher speed (0.18 ns tPD) justifies redesign |
Compared with SN74CBT16210DGGR and 74CBTLV16210PAG, CBTD16210DL,112 uniquely integrates input clamp diodes for native 5 V→3.3 V translation, retains full 5.5 V absolute max rating, and delivers verified 5 Ω Ron across –40°C to +85°C - making it the sole drop-in solution for legacy voltage domain bridging without circuit modification.

FAQ
Is CBTD16210DL,112 pin-compatible with SN74CBT16210?
Yes, CBTD16210DL,112 is mechanically and electrically pin-compatible with TI's SN74CBT16210 in SSOP-48 packages, sharing identical pin numbering, function mapping, and 48-pin footprint. Both support dual 10-bit switching with independent OE control, though CBTD16210DL,112 includes integrated input clamp diodes not present in the TI variant.
Can CBTD16210DL,112 operate with 3.3 V supply?
No - CBTD16210DL,112 requires a minimum VCC of 4.5 V and is rated for 4.5–5.5 V operation only. Its internal clamp diodes and pass-transistor threshold design depend on ≥4.5 V to ensure proper 5 V→3.3 V level translation; operation below 4.5 V is not characterized or guaranteed.
What is the maximum capacitive load supported at full speed?
CBTD16210DL,112 is characterized for 50 pF load capacitance, delivering 0.25 ns propagation delay under that condition. While functional at higher loads, timing parameters degrade linearly with CL; for >50 pF, measured tPD increases approximately 0.01 ns/pF due to RC constant effects from 5 Ω Ron and load capacitance.
Does CBTD16210DL,112 support hot insertion?
No - CBTD16210DL,112 is not hot-plug rated. Its absolute maximum rating allows VCC = –0.5 V to +7.0 V, but the absence of Ioff (power-off protection) specification means outputs may source current when VCC is absent, risking damage during live insertion. External hot-swap circuitry is required for such use cases.
