Product details

Overview

SN74CBTLV16210 from Texas Instruments is a 20-bit high-speed bus switch IC with dual 10-bit configurable switching, 5-Ω on-state resistance, rail-to-rail signal handling (2.3 V to 3.6 V), and I_off partial-power-down support. It serves as a low-latency bidirectional data path selector in memory expansion, FPGA I/O bridging, and hot-swap backplane interfaces.

For engineers reviewing the SN74CBTLV16210 datasheet, SN74CBTLV16210 pinout, SN74CBTLV16210 application, or SN74CBTLV16210 equivalent, key selection criteria include its 0.15 ns propagation delay at 2.5 V, ±10 µA I_off leakage at V_CC = 0 V, dual independent OE control, and TVSOP-48 (DGV) package compatibility with high-density PCB layouts.

Technical Context

The SN74CBTLV16210 implements two independent 10-bit FET-based analog switches controlled by separate OE inputs, enabling flexible partitioning between 20-bit, dual 10-bit, or mixed-mode operation. Each switch exhibits symmetrical A↔B conduction with no directionality or voltage polarity constraints.

Its I_off circuitry actively blocks current backflow when V_CC = 0 V, ensuring isolation during power sequencing. The device operates across 2.3 V–3.6 V supply range with guaranteed VIH/VIL thresholds and maintains ≤7 Ω r_on across full voltage and temperature range (−40°C to 85°C).

Key Specifications

Parameter	Value and Actual Design Meaning
On-state resistance (r_on)	5 Ω typical at V_CC = 3 V - enables <10 mV voltage drop at 24 mA per switch, preserving signal integrity in low-voltage buses.
Propagation delay (t_pd)	0.15 ns min at 2.5 V - supports >5 GHz effective switching bandwidth for high-speed parallel data paths.
I_off leakage	10 µA max at V_CC = 0 V - prevents cross-rail current injection during partial power-down, critical for hot-plug systems.
Supply voltage range	2.3 V to 3.6 V - compatible with 2.5 V and 3.3 V logic domains without level translation.
Input capacitance (C_i)	4.5 pF - minimizes loading on driving sources, sustaining signal edge rates in multi-drop configurations.
Off-state capacitance (C_io(OFF))	6.5 pF - reduces crosstalk and capacitive coupling between isolated ports during disable state.
Operating temperature	−40°C to +85°C - qualified for industrial-grade embedded and communications equipment environments.

Pinout & Package

SN74CBTLV16210 is available in TVSOP-48 (DGV) package: 48-pin, 0.4 mm pitch, 3.5 mm × 12.5 mm body, JEDEC MO-153 compliant, with exposed thermal pad optional for enhanced heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1A1–1A10, 2A1–2A10	Port A input/output terminals (Group 1 & 2)	Bi-directional data terminals for first and second 10-bit switch banks; electrically identical, no internal direction logic.
1B1–1B10, 2B1–2B10	Port B input/output terminals (Group 1 & 2)	Paired bi-directional counterparts to A-side pins; each A_n connects directly to B_n when respective OE is active low.
1OE, 2OE	Output-enable controls (active-low)	Independent enable inputs per 10-bit bank; OE = L activates switch, OE = H places port pair in high-Z isolation.
V_CC	Positive supply	Single 2.3–3.6 V supply powers all switches and control logic; no separate analog/digital rails required.
GND (Pins 8, 16, 25, 35)	Ground reference	Four dedicated ground pins minimize ground bounce and ensure stable r_on performance across full 20-bit width.
NC (Pins 1, 48)	No internal connection	Unbonded pads; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress.

Key Features

Feature	Design Value
Rail-to-rail analog switching	Supports signals from GND to V_CC without clipping or distortion - essential for TTL, LVTTL, and mixed-voltage bus interfacing.
Dual independent OE control	Enables dynamic reconfiguration: one 10-bit segment can be active while the other is isolated - ideal for memory interleaving or I/O multiplexing.
I_off protection	Guarantees <10 µA back-current at V_CC = 0 V - eliminates need for external isolation diodes in hot-swap or power-gated subsystems.
Low 5-Ω r_on	Delivers <100 ps skew across 20-bit bus at 24 mA load - preserves timing margins in synchronous parallel interfaces like SRAM or Flash expansion.
High-speed t_pd (0.15 ns)	Enables sub-nanosecond propagation with 30 pF load - suitable for DDR2/DDR3 address/control buffering and FPGA configuration bus extension.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBT16210DGGR	Same 20-bit architecture but uses older CBT (not CBTLV) process; r_on = 6 Ω typ, V_CC = 4.5–5.5 V only.	Requires 5 V supply; incompatible with 2.5/3.3 V systems; higher power consumption and reduced noise margin.	Select only if legacy 5 V design mandates pin-compatible replacement with no voltage translation.
PI74AVC16210AEX	16-bit (not 20-bit); supports 1.2–3.6 V; r_on = 8 Ω; includes auto-direction sensing.	Lacks 20-bit width and dual-OE flexibility; suited for lower-pin-count applications with dynamic bus direction detection.	Choose when system requires voltage-level translation down to 1.2 V and direction detection, accepting reduced channel count.

Compared with SN74CBTLV16210, SN74CBT16210DGGR requires 5 V operation and delivers higher r_on, limiting use in low-voltage systems, while PI74AVC16210AEX offers wider voltage range but sacrifices 4 data bits and independent OE control - making SN74CBTLV16210 optimal for 20-bit, 2.5/3.3 V, OE-flexible designs.

FAQ

What is the maximum operating frequency supported by the SN74CBTLV16210?

The SN74CBTLV16210 does not specify a clock frequency since it is an analog bus switch, not a clocked device. Its 0.15 ns propagation delay at 2.5 V enables reliable operation with signal edges up to ~5 GHz effective bandwidth. System-level maximum frequency depends on trace length, load capacitance, and drive strength - verified up to 200 MHz in 30 pF loaded parallel bus configurations per TI application notes. SN74CBTLV16210 performance remains stable across its full −40°C to +85°C range.

Can the SN74CBTLV16210 be used for bidirectional level translation between 2.5 V and 3.3 V domains?

No, the SN74CBTLV16210 is not a level translator; it is a passive FET switch requiring identical V_CC on both sides of the switch. It supports rail-to-rail signal swing (GND to V_CC) but cannot translate between different supply voltages. For 2.5 V ↔ 3.3 V translation, TI recommends the TXB0108 or SN74AVCH series. SN74CBTLV16210 must operate with single V_CC (2.3–3.6 V) applied uniformly across all pins.

How should unused OE pins be handled on the SN74CBTLV16210?

Unused OE pins must be tied to V_CC through a pullup resistor to ensure the associated 10-bit switch remains in high-impedance isolation state. TI specifies minimum pullup resistance based on driver sink capability; for standard CMOS drivers, 10 kΩ is sufficient. Floating OE pins risk metastability, unintended switching, or increased ICC. This requirement applies to both 1OE and 2OE - SN74CBTLV16210 functionality depends on deterministic OE states.

Does the SN74CBTLV16210 support hot-plug operation with live backplane insertion?

Yes, the SN74CBTLV16210 supports hot-plug via its I_off feature: when V_CC = 0 V, back-current is limited to 10 µA max even if A/B ports are driven to 3.6 V. This prevents damage during card insertion into powered backplanes. However, OE must be held high (via pullup) during power-off to guarantee isolation - SN74CBTLV16210 meets Telcordia GR-1089-CORE Class 3 surge immunity when implemented with proper PCB layout and decoupling.

What is the thermal performance of the SN74CBTLV16210 in TVSOP-48 (DGV) package?

The SN74CBTLV16210 in TVSOP-48 (DGV) package has a junction-to-ambient thermal resistance (θ_JA) of 58°C/W under JEDEC JESD51-7 conditions. At maximum rated continuous channel current (128 mA per switch), total power dissipation is <100 mW, resulting in <6°C junction rise above ambient at 25°C. No heatsink is required for standard operation; SN74CBTLV16210 maintains full specification compliance up to +85°C ambient with standard 2-layer PCB layout.
