Product details

Overview

74CBTLV16292PAG8 from Renesas Electronics is a low-voltage 12-bit 1:2 multiplexer/demultiplexer bus switch with internal 500Ω pull-down resistors, 5Ω typical on-resistance, 250ps max propagation delay, and operation across 2.3V–3.6V supply at –40°C to +85°C. It enables high-speed bidirectional signal routing in 3.3V bus isolation and resource-sharing applications.

For engineers reviewing the 74CBTLV16292PAG8 datasheet, 74CBTLV16292PAG8 pinout, 74CBTLV16292PAG8 application, or 74CBTLV16292PAG8 equivalent, key selection criteria include its make-before-break timing (0–2 ns), over-voltage tolerance, power-off isolation, and TSSOP-56 package compatibility with industrial-grade thermal stability.

Technical Context

The 74CBTLV16292PAG8 implements a single-pole double-throw (SPDT) analog switch architecture per bit, controlled by one global select input (S). Each of the 12 bidirectional channels features identical 5Ω R_ON and <250ps propagation delay under 3.3V operation.

Its internal 500Ω pull-down resistors are dynamically routed to the unselected B port (B1 or B2) based on S logic level, eliminating floating nodes without external components. The device maintains isolation when V_CC = 0V and supports over-voltage tolerant I/O up to 4.6V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.3V to 3.6V - Enables direct interface with 2.5V and 3.3V logic domains without level shifters.
R_ON (Typ)	5Ω - Minimizes voltage drop and signal distortion for 64mA channel current capability.
t_PD (Max)	0.25ns - Supports >1 GHz digital switching in high-speed memory or data-path isolation.
Make-Before-Break	0–2ns - Prevents signal glitches during port switching in hot-swap or dynamic reconfiguration.
Power-Off Isolation	IOFF ≤ 10µA at VCC = 0V - Blocks leakage between A and B ports when system rail is inactive.
ESD Rating	2000V HBM / 200V MM - Meets industrial robustness requirements without external protection.
Operating Temp	–40°C to +85°C - Qualified for industrial control, networking, and embedded computing environments.

Pinout & Package

74CBTLV16292PAG8 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 pad not present. Pin 1 is marked via top-side dot; pins 29 and 30 are NC; pins 17, 25, and 43 are GND; pin 28 is V_CC.

Pin/Terminal	Circuit Role	Design Meaning
S	Select Control Input	Active-HIGH logic selects A→B2 path; LOW selects A→B1 path while routing pull-down to opposite B port.
1A–12A	Common Port (Bidirectional)	12-channel analog/data bus interface; connects to shared system resource (e.g., memory controller).
1B1–12B1	First Output Port (Bidirectional)	When S = LOW, connected to corresponding A pin; otherwise isolated and pulled down via internal 500Ω resistor.
1B2–12B2	Second Output Port (Bidirectional)	When S = HIGH, connected to corresponding A pin; otherwise isolated and pulled down via internal 500Ω resistor.

Key Features

Feature	Design Value
5Ω Bi-directional Switch	Enables minimal insertion loss and near-transparent signal coupling for DDR, PCIe, or parallel bus signals.
Internal 500Ω Pull-down Resistors	Eliminates need for 24 external resistors in 12-bit demux configuration, reducing BOM count and layout area.
Make-Before-Break Timing	Guaranteed 0–2ns overlap prevents open-circuit transients during dynamic port reassignment.
Over-Voltage Tolerance	Withstands up to 4.6V on I/O pins independent of V_CC, enabling safe interfacing with mixed-voltage subsystems.
Power-Off Isolation	Maintains <10µA off-state leakage when V_CC = 0V, supporting true hot-swap and partial-power-down modes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTLV16292PAG	Same pinout, identical electrical specs, but supplied in tube packaging (non-reel); no functional difference.	No change in circuit design or layout; differs only in logistics handling and minimum order quantity.	Select 74CBTLV16292PAG8 for tape-and-reel automated assembly; choose SN74CBTLV16292PAG for prototyping or low-volume hand-soldered builds.
74LVC1G3157GW,125	Single-channel SPDT switch in SC-70-6; R_ON = 10Ω; no internal pull-down; requires 12x units for full 12-bit coverage.	Not scalable to 12-bit without 12 discrete packages; lacks integrated pull-downs and make-before-break timing guarantee.	Use only for low-pin-count or space-constrained designs where full 12-bit integration is unnecessary.

Compared with SN74CBTLV16292PAG and 74LVC1G3157GW,125, the 74CBTLV16292PAG8 delivers consolidated 12-bit switching with guaranteed make-before-break, internal termination, and industrial temperature support - reducing component count, layout complexity, and qualification effort in high-reliability systems.

FAQ

What is the maximum operating frequency supported by the 74CBTLV16292PAG8?

The 74CBTLV16292PAG8 does not specify a clock frequency since it is an analog bus switch, not a synchronous device. Its 0.25ns maximum propagation delay supports signal edge rates compatible with >1 GHz digital buses such as DDR3/DDR4 address/control lines and PCIe Gen1/Gen2 sideband signals. System-level bandwidth is limited by PCB trace impedance and load capacitance, not by the 74CBTLV16292PAG8's intrinsic switching speed.

Does the 74CBTLV16292PAG8 require external pull-up or pull-down resistors?

No - the 74CBTLV16292PAG8 integrates internal 500Ω pull-down resistors on all B1 and B2 ports, automatically routed to the unselected port based on the S input state. This eliminates the need for 24 external resistors in a full 12-bit configuration, simplifying layout and improving signal integrity during idle states.

Can the 74CBTLV16292PAG8 be used with 2.5V logic systems?

Yes - the 74CBTLV16292PAG8 operates across 2.3V to 3.6V, fully supporting 2.5V ±0.2V and 3.3V ±0.3V supply conditions. Its VIH/VIL thresholds scale with V_CC, ensuring reliable S-input recognition and consistent R_ON performance (3–7Ω typical at 2.5V) without level translation.

Is the 74CBTLV16292PAG8 pin-compatible with earlier IDT CBTLV devices?

The 74CBTLV16292PAG8 shares identical pinout and functionality with the original IDT 74CBTLV16292PAG, including TSSOP-56 footprint, S-control mapping, and internal pull-down routing. No PCB changes are required when migrating from IDT-branded to Renesas-branded 74CBTLV16292PAG8 units.

What is the significance of the '8' suffix in 74CBTLV16292PAG8?

The '8' suffix in 74CBTLV16292PAG8 indicates tape-and-reel packaging (1000 units per reel), optimized for automated SMT placement. This contrasts with the base part number 74CBTLV16292PAG, which denotes tube packaging. Electrical, thermal, and functional specifications are identical between both variants.
