Description

The SN74CBTLV3245APWR is a dual 4-channel bus switch designed for high-speed digital signal switching. It operates with a voltage supply range of 1.65V to 3.6V, making it suitable for low-voltage applications. The device features low ON resistance (typically 5Ω at 3.3V), ensuring minimal signal distortion and power loss during transmission.
As a bus switch, it allows for seamless data flow between two sets of devices while isolating the two sides when disabled, thus preventing signal degradation. The device has a high-speed switching capability, with a typical propagation delay of around 3.5 ns. This makes it appropriate for applications in communication, data routing, and multiplexing.
The SN74CBTLV3245APWR is available in a 20-pin TSSOP package, which provides a compact footprint for space-constrained designs. It is widely used in consumer electronics, telecommunications, and computer systems, where reliable and efficient data management is essential.

Features

The SN74CBTLV3245APWR is a high-speed dual-bit bus switch designed for low-voltage applications. Key features include:
1. Dual 2-Channel Configuration: It has two independent switches that can control two data lines simultaneously.
2. Low ON Resistance: Offers minimal signal distortion and power consumption, typically around 5Ω at VCC = 3.3V.
3. Wide Supply Voltage Range: Operates between 1.65V and 5.5V, making it suitable for various logic levels.
4. High-Speed Operation: Capable of switching speeds up to 170 Mbps, facilitating fast data transfer.
5. Active Low Control: The switch is enabled when the control signal is low, allowing for simple interfacing.
6. Power Down High-Impedance State: When disabled, the I/O pins are high impedance, preventing bus contention.
7. ESD Protection: Provides enhanced protection against electrostatic discharge, improving reliability.
8. Small Package: Available in a TSSOP package, suitable for space-constrained applications.
These features make the SN74CBTLV3245APWR ideal for data routing in communication and consumer electronics.

Package

The SN74CBTLV3245APWR is available in a TSSOP (Thin Shrink Small Outline Package) package type, specifically with 20 pins.

Pinout

The SN74CBTLV3245APWR is a 24-pin, dual bidirectional bus switch from Texas Instruments. It is designed for high-speed data transmission and is particularly useful in applications requiring low on-state resistance and minimal propagation delay.
Pin Count: 24 pins
Function: The device features two independent, bidirectional switches that allow for the connection of two buses. Each switch is controlled by an enable signal (OE) that determines whether the corresponding bus is connected or disconnected. It operates with a supply voltage range of 1.65V to 3.6V and supports data rates up to 1 Gbps, making it suitable for various digital applications, including signal buffering, level shifting, and connecting different voltage domains.
