Status Update and Competitive Comparison

X-ray of Competitor’s 3L500 device

Physical comparison of TI vs Competitor

Due to the competitor’s die aspect ratio, the design is not optimized for the applicationThe increased width of the die, increases RON and effective net delay because of the physical increase in input to output circuitryPlacement of the bond pads makes it difficult to match specs from one channel to otherWire lengths to the end pins are 3x the length of the wires to the center pins; adds to the delta RON/CON

Assembly file for Competitor’s design

Assembly file for TI’s TS3L500 design

Staggered bond pad allows for a slimmer die width and optimized wire bondsTI’s High Aspect Ratio Chip (HARC) design allows us to reduce the physical silicon area from input-to-output to achieve:

• Lower RON and delta RON (channel-to-channel)• Lower CON and delta CON (channel-to-channel)• Improved pin-to-pin skew performance which is

critical for this application

Translation Characteristics

Availability: NOW


Translation circuitry Translates 5V Input Down to 3.3V Output Level Shift with 3.3V VccTranslates 5V/3.3V Input Down to 2.5V Output Level Shift with 2.5V Vcc.

Ioff Maintains isolation when Vcc = 0V

5V Tolerant I/Os Protects non over-voltage tolerant I/Os from signals or noise greater than Vcc

Low power Power efficient design helps extend battery life

Key Specifications • VCC Operating Range From 2.3 V to 3.6 V• Control Inputs Can Be Driven by TTL or 5-V/3.3-V CMOS Outputs• Data and Control Inputs Provide Undershoot Clamp Diodes

Device DescriptionThe SN74CB3T3384 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (Ron). The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC.

Translation Switch CB3T3384

Device DescriptionThis 8-bit (dual-octal) noninverting bus transceiver uses two separate configurable power-supply rails enabling communication between components operating a unequal voltages.

Logic Diagram

Availability: Now


Translation Allows components operating at different voltages to communicate

Vcc Isolation Disables both I/O ports if either Vcc is at GND.

Fully configurable dual-rail design

Each port to operates over the full 1.4V to 3.6V power supply range enabling a wide range of translation

Ioff Supports partial power down mode operation

Key Specifications• VCCA, VCCB = 1.4V to 3.6V • ICCA, ICCB < 10µA • Drive = -12mA/12mA @ 3.3V• TPD < 2.2nS @ 3.3V To Seven Other Channels

Standard Linear and Logic Content in ServersMultiplexing USB Peripherals

Device DescriptionThe SN74CB3Q3125 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (Ron).


Charge pump and Low, Flat Ron Minimizes propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports.


Low power Icc = 0.25mA (typ) helps extend battery life

Low data IO capacitance Minimizes capacitive loading and signal distortion on the data bus

Key Specifications• High-Bandwidth Data Path ( Up to 500 MHz )• Provides Low and Flat Ron (4Ω typ)• Supports Rail-to-Rail I/O ( RRIO ) Switching from 0V to 5V • VCC Operating Range from 2.3V to 3.6V 1 2 3 4 5
