74LVX161284MTDX

Overview

The onsemi 74LVX161284MTDX is a translating transceiver designed for IEEE Std 1284 parallel port applications. It features an 8-bit data path with four address lines and control signals, facilitating bidirectional communication between systems operating at different voltage levels. The device supports both unidirectional and bidirectional modes, enabling flexible interface configurations. Packaged in a 48-TSSOP format, it operates within a supply voltage range of 2V to 3.6V and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports IEEE Std 1284 standard for parallel port interfacing
• Provides bidirectional data transmission capability
• Enables voltage translation between disparate logic families

Applications

• Parallel port interface circuits
• Data acquisition systems requiring voltage level shifting
