Product details
Overview
74CBTLV16292PAG from Renesas Electronics is a low-voltage 12-bit 1:2 multiplexer/demultiplexer bus switch with internal 500Ω pull-down resistors on all B-side ports, 5Ω typical ON-resistance, 250ps max propagation delay, and operation across 2.3V–3.6V supply. It enables high-speed bidirectional bus isolation and resource sharing in industrial 3.3V systems.
For engineers reviewing the 74CBTLV16292PAG datasheet, 74CBTLV16292PAG pinout, 74CBTLV16292PAG application, or 74CBTLV16292PAG equivalent, key selection criteria include make-before-break timing (0–2 ns), power-off isolation, over-voltage tolerance up to 4.6V, and TSSOP-56 package compatibility with dense PCB layouts.
Technical Context
The 74CBTLV16292PAG implements a single-pole double-throw (SPDT) analog switch architecture per bit, controlled by one global select input (S). Each of the 12 A/B channel pairs operates bi-directionally with sub-5Ω RON at VCC = 3.3V and IO = 24mA, delivering <0.25ns propagation delay between A and either B1 or B2 port.
Its internal 500Ω pull-down resistors are dynamically routed to the unselected B port (B1 or B2) based on S logic level-ensuring no floating nodes during demux operation-while maintaining latch-up immunity (>100mA) and ESD robustness (>2000V HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V–3.6V - supports 2.5V and 3.3V system rails without level translation |
| RON (Typ) | 3Ω–11Ω - enables <250ps signal path delay and minimal voltage drop under 24mA load |
| tPD (A↔B) | 0.15–0.25ns - meets high-speed parallel bus timing budgets for DDR/PCIe auxiliary control paths |
| tMB/B | 0–2ns - guarantees glitch-free switching during dynamic bus reconfiguration |
| Pull-down Resistor | 500Ω to GND on unselected B port - eliminates floating inputs without external components |
| IOFF (VCC = 0V) | ≤10µA - ensures true signal isolation when powered down, critical for hot-swap subsystems |
| ESD Rating | ≥2000V HBM - sustains handling and board-level stress in industrial assembly environments |
Pinout & Package
74CBTLV16292PAG is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP), measuring 14.0mm × 6.1mm × 1.2mm, with 0.5mm pitch and exposed thermal pad (non-electrical). Pin 1 is marked via top-side dot; pins 29 and 30 are NC; pins 17, 25, and 42 are GND; pin 38 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S | Select Control Input | Active-HIGH logic selects A→B2 path; LOW selects A→B1 path and routes 500Ω pull-down to opposite B port |
| 1A–12A | Common Bidirectional Port | 12-channel analog/data bus interface; connects to shared system resources (e.g., memory controller, FPGA I/O) |
| 1B1–12B1 / 1B2–12B2 | Dual Demux Outputs | Two independent 12-bit output buses; only one set active at a time; unselected set pulled to GND via internal 500Ω |
| GND (Pins 17,25,42) | Ground Reference | Three dedicated ground pins minimize ground bounce across high-speed switching channels |
| VCC (Pin 38) | Power Supply | Single 2.3–3.6V supply powers all 12 switches and internal logic; no separate I/O rail required |
Key Features
| Feature | Design Value |
|---|---|
| Make-before-break switching | Guaranteed 0–2ns overlap prevents signal interruption during port transition in real-time control loops |
| Power-off isolation | IOFF ≤10µA at VCC = 0V enables safe backplane hot-plug without affecting live downstream circuits |
| Integrated 500Ω pull-down | Eliminates need for 24 external resistors on B-side ports, reducing BOM count and layout area |
| Over-voltage tolerant I/O | Withstands VI/O up to 4.6V while VCC = 2.3–3.6V - supports mixed-voltage domain interfacing |
| Latch-up immunity | Exceeds 100mA per JEDEC JESD78 - ensures reliability in noisy industrial power environments |
Applications
| Industrial PLC Backplane Switching | FPGA I/O Resource Sharing |
|---|---|
Use Scenario: Dynamic routing of sensor data buses between multiple CPU modules in modular PLC chassis. IC Role / Device Role / Timing Role: 12-bit SPDT bus switch enabling real-time reconfiguration of analog/digital I/O paths without software intervention. Use Value: Eliminates mechanical relays and external mux ICs, reducing failure points and enabling <2ns deterministic switching latency. | Use Scenario: Sharing limited FPGA GPIO banks among multiple peripheral interfaces (e.g., SPI flash, I²C sensors, UART debug port). IC Role / Device Role / Timing Role: Low-RON bidirectional analog switch extending FPGA pin count without adding logic overhead or timing uncertainty. Use Value: Maintains signal integrity at >100MHz due to <0.25ns tPD, and internal pull-downs prevent floating states during mode transitions. |

IC Role / Device Role / Timing Role: High-speed bus switch providing clean break-before-make isolation during failover events. Use Value: 5Ω RON minimizes skew between CA lines; power-off isolation prevents back-driving during module removal. | Use Scenario: Enabling hot insertion of field-replaceable I/O modules into industrial gateway backplanes. IC Role / Device Role / Timing Role: Signal path gate with guaranteed IOFF and over-voltage tolerance protecting host controller during plug-in transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV16292PAP | Same electrical specs; 56-pin TSSOP but with different thermal pad configuration (non-exposed vs. exposed in PAG) | Lower thermal resistance in PAG supports sustained 128mA channel current; PAP may require derating in high-power density layouts | Prefer 74CBTLV16292PAG for thermally constrained industrial designs requiring full 128mA rating |
| 74LVC1G3157GW | Single-channel SPDT switch; 6-pin SOT363; RON = 10Ω typical; no internal pull-downs | Requires 12× discrete units + 24 external 500Ω resistors to match 74CBTLV16292PAG functionality | Choose 74LVC1G3157GW only for ultra-low-volume prototyping where space is not constrained and BOM simplicity is secondary |
Compared with SN74CBTLV16292PAP and 74LVC1G3157GW, the 74CBTLV16292PAG delivers integrated 12-channel switching with on-die termination in a thermally optimized TSSOP-56, reducing PCB area by >70% versus discrete solutions and eliminating 24 external components required by the single-channel alternative.

FAQ
What is the maximum operating temperature range for the 74CBTLV16292PAG?
The 74CBTLV16292PAG is rated for industrial temperature operation from –40°C to +85°C. This range is validated across all electrical parameters including RON, tPD, and IOFF, ensuring reliable performance in factory-floor and outdoor-mounted control systems without derating.
Does the 74CBTLV16292PAG require external pull-down resistors on the B-side ports?
No, the 74CBTLV16292PAG integrates 500Ω pull-down resistors on all B1 and B2 ports. These are automatically routed to the unselected B port (B1 or B2) based on the S input state, eliminating the need for any external termination components in standard demux configurations.
Can the 74CBTLV16292PAG be used with a 2.5V supply voltage?
Yes, the 74CBTLV16292PAG fully supports 2.5V ±0.2V operation. At this voltage, RON remains ≤8Ω (typical 5Ω), tPD stays within 2.5–7.1ns, and all DC characteristics-including VIH/VIL thresholds and ICC-are guaranteed per the datasheet's operating conditions table.
Is the 74CBTLV16292PAG pin-compatible with earlier IDT CBTLV16292 variants?
Yes, the 74CBTLV16292PAG maintains identical pinout, function table, and AC/DC specifications with all prior IDT-branded CBTLV16292 devices in TSSOP-56 (PAG56) packaging, including legacy part numbers such as IDT74CBTLV16292PAG. No PCB redesign is needed for drop-in replacement.
What is the significance of the "make-before-break" feature in the 74CBTLV16292PAG?
Make-before-break ensures that the new connection (e.g., A→B2) is established before the previous path (A→B1) is broken-guaranteeing continuous signal continuity during switching. For the 74CBTLV16292PAG, this overlap is bounded at 0–2ns, preventing glitches in clock, reset, or control signals routed through the device.
