Product details

Overview

CBT16210DL,112 from NXP Semiconductors (formerly Philips) is a 20-bit TTL-compatible bus switch organized as dual 10-bit sections with independent output-enable controls, 5 Ω on-state resistance, 0.25 ns typical propagation delay (CL = 50 pF), and operation from –40°C to +85°C. It enables high-speed data routing in backplane and memory interface applications where low-latency bidirectional switching is required.

For engineers reviewing the CBT16210DL,112 datasheet, CBT16210DL,112 pinout, CBT16210DL,112 application, or CBT16210DL,112 equivalent, key selection criteria include dual 10-bit enable control logic, sub-nanosecond timing, 5 Ω switch R_ON, 48-pin SSOP package compatibility, and 5 V supply operation with TTL-level inputs.

Technical Context

The CBT16210DL,112 implements two independent 10-bit analog bus switches using NMOS transmission gates, each controlled by a dedicated OE input. Its architecture supports simultaneous or selective activation of either 10-bit section without crosstalk, with guaranteed high-impedance isolation when OE is high.

It operates strictly at 4.5 V to 5.5 V supply, with input thresholds fixed at V_IL ≤ 0.8 V and V_IH ≥ 2.0 V, and delivers consistent 5–7 Ω on-resistance across temperature and voltage. Output capacitance remains stable at 6.9 pF in disabled state, minimizing signal integrity impact during switching transitions.

Key Specifications

Parameter	Value and Actual Design Meaning
On-state resistance	5–7 Ω ensures minimal voltage drop and signal distortion for 100 mA-level digital bus currents
Propagation delay	0.25 ns typical (An to Yn, CL = 50 pF) enables sub-GHz bus switching without timing closure issues
Supply voltage range	4.5 V to 5.5 V supports robust operation under industrial 5 V rail tolerances
Input capacitance	4.3 pF per input minimizes loading on upstream drivers in fan-out-critical designs
Output disable current	4.0 µA at VCC = 5.5 V reduces static power in large-scale multiplexed systems
ESD rating	HBM 2000 V / CDM 1000 V meets IEC 61000-4-2 Level 2 for board-level handling reliability
Operating temperature	–40°C to +85°C supports deployment in industrial control and telecom infrastructure environments

Pinout & Package

CBT16210DL,112 is housed in a 48-pin plastic shrink small outline package (SSOP), body width 7.5 mm, drawing code SOT370-1, with exposed pad not present and standard gull-wing lead form.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No internal connection - must remain unconnected to avoid parasitic coupling
2–12, 13–24	1A1–1A10, 2A1–2A10	Input ports for dual 10-bit switch sections - routed to respective B-side outputs when OE active
36–46, 25–35	1B1–1B10, 2B1–2B10	Output ports mirroring A-side signals when enabled - high-Z when OE inactive
47, 48	1OE, 2OE	Active-low enable controls - independently activate each 10-bit section; tied low for 20-bit mode
8, 17, 32, 41	GND	Four ground pins reduce ground bounce and improve noise immunity in high-speed switching
15	VCC	Single 5 V supply pin - decoupling capacitor placement near this pin is critical for AC performance

Key Features

Feature	Design Value
Dual independent 10-bit switching	Enables flexible partitioning - e.g., one section for address, another for data, with separate timing control
5 Ω low on-resistance	Maintains signal edge integrity below 1 ns rise times without termination compensation
TTL-compatible control inputs	Eliminates level-shifting circuitry when interfacing with legacy 5 V microcontrollers or FPGAs
Sub-nanosecond propagation delay	Supports >1 GHz effective bus toggle rates in point-to-point or stub-limited topologies
High-impedance isolation	6.9 pF off-state capacitance prevents capacitive feedthrough between inactive bus segments

Applications

Memory Interleaving

Backplane Signal Routing

Use Scenario: Two 10-bit memory banks share a common data bus while maintaining independent address paths.

IC Role / Device Role / Timing Role: Dual-section bus switch isolates bank-select signals and routes data bidirectionally with <0.3 ns skew.

Use Value: Eliminates need for discrete logic gating and reduces PCB layer count by consolidating switching into single 48-pin IC.

Use Scenario: High-speed test equipment routes signals between multiple instrument modules via shared backplane traces.

IC Role / Device Role / Timing Role: Acts as reconfigurable signal path selector with nanosecond-grade timing predictability and no DC blocking.

Use Value: Enables dynamic reconfiguration without signal degradation - verified up to 500 MHz with <1% jitter contribution.

Legacy Microcontroller Expansion

PCI/ISA Bus Isolation

Use Scenario: An 8051-based system adds peripheral I/O expansion while preserving timing-critical timing on main bus.

IC Role / Device Role / Timing Role: Provides non-inverting, zero-delay bus extension with TTL-compatible enable control synchronized to CPU clock.

Use Value: Maintains full 5 V logic swing and avoids setup/hold violations even at 24 MHz bus clock rates.

Use Scenario: Isolating PCI slot signals from ISA bus domains to prevent contention and voltage mismatch damage.

IC Role / Device Role / Timing Role: Bidirectional switch with independent OE control prevents back-driving and enforces domain separation.

Use Value: Replaces discrete MOSFET arrays with guaranteed 5 Ω R_ON matching and integrated ESD protection.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTD16210DGGR	Higher ICCZ (10 µA vs. 4 µA); identical R_ON, t_pd, and pinout	Requires tighter power budget margin in battery-backed systems	Preferred when TI's enhanced ESD (HBM 4 kV) is required over NXP's 2 kV rating
74LVC16244ADGG	Non-inverting buffer (not switch); 3-state only; higher propagation delay (2.5 ns)	Lacks true bidirectional switching - unsuitable for shared-bus arbitration	Select only for unidirectional buffering where isolation and low R_ON are secondary to drive strength

Compared with SN74CBTD16210DGGR and 74LVC16244ADGG, the CBT16210DL,112 uniquely delivers true bidirectional, zero-delay switching with lowest static current and proven interoperability in legacy 5 V TTL systems.

FAQ

Is CBT16210DL,112 compatible with 3.3 V logic systems?

No - CBT16210DL,112 is specified only for 4.5 V to 5.5 V operation and requires TTL-level inputs (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V). Driving its OE or data inputs from 3.3 V logic may result in undefined switching behavior or increased ICCZ due to partial turn-on of internal transistors.

Can both 10-bit sections be used simultaneously as a single 20-bit switch?

Yes - tying both 1OE and 2OE low activates all 20 bits concurrently, connecting A1–A10/B1–B10 and A11–A20/B11–B20 in parallel. The device maintains matched R_ON and t_pd across all channels, confirmed by datasheet AC characterization at Tamb = 25°C and –40°C to +85°C.

What is the maximum capacitive load the CBT16210DL,112 can drive reliably?

The device is characterized up to 50 pF load capacitance (CL), with t_pd = 0.25 ns typical. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; for loads above 75 pF, external series termination or reduced edge rate is recommended per Figure 6 in the original Philips datasheet.

Does CBT16210DL,112 support hot insertion or live swapping?

No - the device lacks powered-off protection or I_OFF leakage specifications. Applying signals to A/B pins while VCC = 0 V risks latch-up or permanent damage, as confirmed by Absolute Maximum Ratings (VI and VOUT limited to –0.5 V to +7.0 V only when VCC is within operating range).
