Product details
Overview
CBTD16210DL,118 from NXP Semiconductors (formerly Philips) is a 20-bit TTL-compatible bus switch with dual 10-bit output-enable control, designed for 5.5 V to 3.3 V level shifting. It features 5 Ω on-state resistance, 0.25 ns typical propagation delay (CL = 50 pF), and operates from –40°C to +85°C in a 48-pin SSOP package. It enables bidirectional signal routing in mixed-voltage memory and data bus interfaces.
For engineers reviewing the CBTD16210DL,118 datasheet, CBTD16210DL,118 pinout, CBTD16210DL,118 application, or CBTD16210DL,118 equivalent, key selection criteria include verified level-shifting capability between 5 V and 3.3 V domains, dual independent OE control for segmented bus management, low-capacitance switching (CIN = 4.3 pF, COUT = 6.9 pF), and industrial temperature range compliance.
Technical Context
The CBTD16210DL,118 implements two independent 10-bit transmission-gate arrays with integrated input clamping diodes to VCC, enabling safe 5 V → 3.3 V level translation without external components. Each channel supports bidirectional signal flow when enabled, with high-impedance isolation when OE is high.
Its architecture uses low-threshold MOS pass transistors with TTL-compatible control inputs (VIH = 2.0 V, VIL = 0.8 V) and supports simultaneous or staggered enable timing-tPZH = 5.0 ns max, tPHZ = 2.5 ns max-making it suitable for synchronous bus gating in legacy-to-modern interface bridging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance | 5 Ω typical - ensures minimal voltage drop and signal distortion during active switching |
| Propagation delay | 0.25 ns typical (An to Yn, CL = 50 pF) - supports high-speed bus operation up to ~1 GHz effective bandwidth |
| Input capacitance | 4.3 pF - reduces loading on upstream drivers and preserves signal edge integrity |
| Supply voltage range | 4.5 V to 5.5 V - compatible with standard 5 V logic rails while enabling 3.3 V output translation |
| Operating temperature | –40°C to +85°C - qualified for industrial-grade embedded and telecom infrastructure use |
| Output enable time | 5.0 ns max (tPZH) - allows tight timing alignment in clock-synchronized bus arbitration |
| Quiescent supply current | 1.5 mA max - minimizes static power in always-on interface bridges |
Pinout & Package
CBTD16210DL,118 is housed in a 48-pin plastic shrink small outline package (SSOP), SOT370-1, 7.5 mm body width, with exposed pad not present and standard gull-wing lead form.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left unconnected or tied to GND per layout guidelines |
| 2–12, 13–24 | 1A1–1A10, 2A1–2A10 | Input ports for dual 10-bit buses - accept 5 V TTL signals and translate to 3.3 V outputs |
| 25–35, 36–46 | 2B1–2B10, 1B1–1B10 | Output ports for dual 10-bit buses - deliver level-shifted 3.3 V signals with 6.9 pF load capacitance |
| 47–48 | 1OE, 2OE | Active-low output enables - independently gate each 10-bit segment; OE = L enables A↔B path |
| 8, 17, 32, 41 | GND | Ground reference pins - four dedicated GND connections reduce ground bounce in high-speed switching |
| 15 | VCC | Positive supply pin - powers internal clamp diodes and switch transistors; requires local 100 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 10-bit bus switches | Enables flexible partitioning - e.g., one segment for address lines, another for data lines - with separate timing control |
| Integrated VCC-clamp diodes | Eliminates need for external protection diodes when interfacing 5 V inputs to 3.3 V systems |
| TTL-compatible control inputs | Accepts standard 5 V logic thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) without level-shifting circuitry |
| Low 4.3 pF input capacitance | Preserves rise/fall times of fast-switching signals and reduces driver loading in fan-out-critical designs |
| Industrial temperature rating | Validated operation from –40°C to +85°C - suitable for base station backplanes and industrial PLC I/O modules |
Applications

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 with identical 20-bit dual-OE architecture, but higher ron (6.5 Ω typ) and wider tPZH (6.5 ns max) | Same functional role; slightly reduced speed margin in >80 MHz bus environments | Select if TI supply chain preference exists and 1 ns enable-time margin is acceptable |
| 74LVC16245ADGG | Octal non-inverting transceiver (16-bit), no level-shifting diodes; requires external biasing for 5 V→3.3 V | Unidirectional only; lacks integrated clamping - adds 2× external diodes and resistors per channel | Choose only when bidirectional operation is unnecessary and board space permits discrete support components |
Compared with SN74CBT16210DGGR and 74LVC16245ADGG, CBTD16210DL,118 delivers superior level-shifting integration, lower on-resistance, and tighter enable timing-making it optimal for compact, high-reliability mixed-voltage bus bridges where component count and thermal stability are critical.

FAQ
Can CBTD16210DL,118 operate with a 3.3 V supply voltage?
No. CBTD16210DL,118 requires a minimum VCC of 4.5 V and is specified only for 4.5 V to 5.5 V operation. Its internal clamp diodes and pass transistor threshold design depend on this supply range to achieve correct 5 V → 3.3 V level shifting. Using 3.3 V on VCC will result in undefined output behavior and potential damage.
What is the maximum capacitive load supported per switched line?
The device is characterized for CL = 50 pF per output, with propagation delay and timing parameters guaranteed under that condition. While it may function with higher loads, tpd increases linearly with capacitance (per RC model), and exceeding 75 pF risks violating setup/hold margins in >50 MHz synchronous buses. Layout best practice limits trace + stub capacitance to ≤40 pF.
Is the NC pin (Pin 1) required to be grounded?
No. Pin 1 is a true no-connect with no internal bond wire. It may be left floating, tied to GND, or used as a test point-none affects functionality. However, grounding it improves mechanical stability during reflow and reduces potential for solder bridging in dense layouts, so it is recommended but not mandatory.
Does CBTD16210DL,118 support hot-swap or live-insertion?
It supports limited hot-swap capability due to its integrated clamp diodes and high-impedance off-state (ICCZ = 4.0 µA), but it is not fully hot-swap rated. Power sequencing must ensure VCC is stable before applying input signals, and OE should be held high until power is settled. For full hot-swap compliance, external current-limiting and sequencing ICs are required.
