Description

The 74CBTLV3245PW is a dual 8-channel bus switch designed for high-speed data transfer and signal routing in digital applications. It features a low on-resistance, allowing it to minimize power loss and maintain signal integrity. The device operates with a voltage range of 1.65V to 3.6V, making it suitable for interfacing between various logic families and power domains.
In its 48-pin TQFP package, the 74CBTLV3245PW allows for efficient routing of signals across circuits. The bus switches enable bidirectional data flow, making them ideal for applications like data multiplexing, level shifting, and signal isolation. The device is designed to provide minimal propagation delay, ensuring reliable performance in high-speed environments.
It also includes features such as over-voltage tolerance and active pull-up resistors, enhancing its robustness in varied operating conditions. This makes the 74CBTLV3245PW a versatile component for use in consumer electronics, networking, and communication systems.

Features

The 74CBTLV3245PW is a 16-bit bus switch designed for high-speed digital applications. It features low ON resistance (typically around 5 ohms) and operates from a wide supply voltage range of 1.65V to 3.6V, making it suitable for a variety of logic levels. The device is optimized for low power consumption, allowing for efficient operation in battery-powered applications.
Key features include:
- 16-channel bus switch: Facilitates easy switching between multiple data lines.
- Bidirectional switching: Supports data flow in both directions without the need for control signals.
- Low power dissipation: Minimal power loss during operation.
- Fast switching speeds: Suitable for high-frequency applications.
- TTL-compatible: Compatible with standard TTL logic levels.
- Pin and function compatible: Compatible with other similar bus switches for easy design transitions.
The 74CBTLV3245PW is ideal for applications in portable devices, communication equipment, and data routing tasks.

Package

The 74CBTLV3245PW is housed in a TSSOP (Thin Shrink Small Outline Package) package type, specifically in a 20-pin format.

Pinout

The 74CBTLV3245PW is a 24-bit dual supply bus transceiver designed for high-speed data transmission. It features a total of 32 pins. The primary functions include:
- Data Input/Output: 24 data lines (D0 to D23) for bidirectional data transfer.
- Direction Control: Two control pins (DIR1 and DIR2) to set the direction of data flow.
- Output Enable: An active-low output enable pin (OE) for controlling the output state.
- Power Supply: Support for dual power supply levels, allowing operation from separate VCC and VCCA for interfacing with different logic families.

The device is commonly used in applications requiring data buffering and level shifting between different system voltages.
