概要

Description

The 74LVC8T245PW is an octal dual supply translating transceiver with 3-state outputs, designed for asynchronous communication between data buses. It features dual supply rails, allowing it to translate data between two voltage levels in the range of 1.2V to 5.5V, making it ideal for interfacing between devices operating at different levels. This device is part of the LVC family from Nexperia and is known for its low power consumption and high-speed performance.
Key features include an active-low output enable (OE) for controlling the direction of data flow and isolating the buses when not in use, and an active-low direction control (DIR) for specifying the direction of data transmission. The 74LVC8T245PW supports live insertion and partial power-down mode, allowing for hot swapping and ensuring minimal power usage during idle states. Housed in a TSSOP-24 package, it is suitable for a range of applications including mobile devices, computing, and networking equipment, where efficient and reliable level translation is crucial.

Features

The 74LVC8T245PW is a high-speed, low-power octal bus transceiver with 3-state outputs, designed for asynchronous two-way communication between data buses. Key features include:
1. Dual Supply Voltage Levels: It supports mixed-voltage operation, allowing different voltage levels on the A-side (1.2V to 5.5V) and B-side (1.2V to 5.5V).
2. Bidirectional Data Transfer: Supports bidirectional data transfer with separate input and output enable controls for each direction.
3. High-Speed Operation: Designed for high-speed applications with a maximum data transfer rate of 100 Mbps.
4. 3-State Outputs: Features 3-state outputs for bus-oriented applications, improving signal integrity and reducing bus contention.
5. Low Power Consumption: Incorporates low power consumption features, making it suitable for battery-powered devices.
6. Overvoltage Tolerant Inputs: Inputs are overvoltage tolerant, allowing for better integration with existing systems.
7. Compact Package: Available in a TSSOP-24 package, suitable for space-constrained designs.
These features make the 74LVC8T245PW ideal for applications needing efficient data exchange between different voltage levels, such as in mobile and computing devices.

Pinout

The 74LVC8T245PW is a bidirectional voltage-level translator with an 8-bit bus transceiver function. It is designed to allow data transfer between voltage levels from 1.2V to 5.5V, making it suitable for mixed-signal applications. The device features two supply voltages: VCCA and VCCB. VCCA defines the input voltage threshold, while VCCB defines the output voltage level.
The device comes in a TSSOP (Thin Shrink Small Outline Package) with 24 pins. Key functions include direction control (DIR pin) and output enable (OE pin). The DIR pin determines the direction of data flow (A to B or B to A), and the OE pin enables or disables the output drivers, allowing for high-impedance outputs when needed.
This device is particularly useful in applications requiring interface between different logic levels, such as between microcontrollers and peripheral devices operating at different voltages.
