Product details

Overview

74CBTLV16210PAG8 from Renesas Electronics is a low-voltage 20-bit bus switch operating as either a single 20-bit or dual 10-bit bi-directional switch, featuring 5Ω typical ON resistance, <0.25 ns propagation delay, and operation across 2.3V–3.6V supply range for 3.3V high-speed bus isolation in industrial systems.

For engineers reviewing the 74CBTLV16210PAG8 datasheet, 74CBTLV16210PAG8 pinout, 74CBTLV16210PAG8 application, or 74CBTLV16210PAG8 equivalent, key selection criteria include its bi-directional switching capability, power-off isolation, over-voltage tolerance up to 4.6V, and TSSOP-48 package compatibility with dense PCB layouts.

Technical Context

The 74CBTLV16210PAG8 implements two independent 10-bit bus switches controlled by active-low OE inputs (1OE and 2OE), enabling selective isolation of A/B port pairs without directionality constraints. Each switch exhibits sub-5Ω R_ON at V_CC = 3.3V and supports bidirectional signal flow with <250 ps propagation delay under 50 pF load.

It guarantees isolation under power-off conditions (I_OFF ≤ 10 µA at V_CC = 0V), withstands input voltages up to 4.6V regardless of V_CC, and meets MIL-STD-883 ESD ratings (>2000V HBM, >200V MM), making it suitable for hot-swap and mixed-voltage interface applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.3V to 3.6V - supports standard 3.3V logic rails with margin for voltage droop
R_ON (Typ)	5Ω - enables minimal signal attenuation and low insertion loss in high-speed data paths
t_PD Max	0.25 ns - ensures sub-nanosecond timing integrity for >1 GHz digital interfaces
I_OFF Max	10 µA at V_CC = 0V - maintains true high-impedance isolation during power sequencing
VI Absolute Max	–0.5V to +4.6V - allows over-voltage tolerant operation beyond V_CC, critical for level-shifting
ESD Rating	>2000V HBM - provides robust handling in manufacturing and field environments
Operating Temp	–40°C to +85°C - certified for industrial temperature range operation

Pinout & Package

74CBTLV16210PAG8 is housed in a 48-pin Thin Shrink Small Outline Package (TSSOP), measuring 12.5 mm × 6.1 mm × 1.2 mm, with 0.5 mm pitch and exposed pad not present. Pin assignment follows JEDEC MO-153 standard for PAG48.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-low output enable control	Asserting low enables corresponding 10-bit A↔B switch; high disables with high-Z isolation
1A1–1A10, 2A1–2A10	Port A data terminals	Bi-directional I/O pins for first and second 10-bit switch banks
1B1–1B10, 2B1–2B10	Port B data terminals	Bi-directional I/O pins paired with respective Port A lines
V_CC	Power supply	Single 2.3–3.6V supply for all logic and switch circuitry
GND	Ground reference	Common return path for all signals and internal bias networks

Key Features

Feature	Design Value
Bi-directional switching	Enables transparent signal routing in either direction without direction control logic
Power-off isolation	Maintains high-impedance between ports when V_CC = 0V, preventing back-drive and leakage
Over-voltage tolerance	Accepts inputs up to 4.6V independent of V_CC, supporting mixed-voltage domain interfacing
Low propagation delay	<0.25 ns ensures timing-critical links (e.g., memory buses, FPGA interconnects) remain uncompromised
Latch-up immunity	Exceeds 100 mA per JEDEC JESD78, eliminating risk of destructive latch-up in noisy environments

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTLV16210PAG	Same pinout, identical electrical specs, same TSSOP-48 package; manufactured by Texas Instruments	No functional difference; validated for identical use cases including memory isolation and FPGA expansion	Select when TI-sourced supply chain alignment or dual-sourcing strategy is required

FAQ

What is the maximum operating voltage for 74CBTLV16210PAG8 inputs?

The 74CBTLV16210PAG8 supports input voltages from –0.5V to +4.6V, independent of V_CC. This over-voltage tolerance allows safe interfacing with 5V peripherals while operating at 3.3V V_CC, eliminating external clamping diodes in mixed-voltage designs involving the 74CBTLV16210PAG8.

Does 74CBTLV16210PAG8 support hot-swap operation?

Yes, the 74CBTLV16210PAG8 supports hot-swap via guaranteed power-off isolation: when V_CC = 0V, I_OFF remains ≤10 µA, and the switch presents high impedance between A and B ports. This prevents back-driving and bus contention during live insertion, a core requirement for systems using the 74CBTLV16210PAG8 in modular backplanes.

What is the typical ON-resistance of 74CBTLV16210PAG8 at 3.3V?

The typical ON-resistance of the 74CBTLV16210PAG8 is 5Ω at V_CC = 3.3V, measured with VI = 1.7V and IO = 15mA. This low R_ON minimizes voltage drop and signal distortion, directly contributing to the <0.25 ns propagation delay specified for the 74CBTLV16210PAG8 in high-speed bus applications.

How many independent switch banks does 74CBTLV16210PAG8 provide?

The 74CBTLV16210PAG8 provides two independent 10-bit switch banks, each controlled by its own active-low enable pin (1OE and 2OE). This architecture allows selective isolation of two separate 10-bit data paths-such as separate address and data buses-without cross-talk, a key capability leveraged in the 74CBTLV16210PAG8's target applications.

Is 74CBTLV16210PAG8 compatible with standard TSSOP-48 footprints?

Yes, the 74CBTLV16210PAG8 uses the industry-standard TSSOP-48 package (PAG48) with 0.5 mm pitch and JEDEC MO-153 dimensions (12.5 mm × 6.1 mm). Its pinout matches the generic 48-pin TSSOP layout, ensuring drop-in compatibility with existing PCB footprints designed for similar logic devices, including those used for the 74CBTLV16210PAG8 in industrial control boards.
