74ABT16500CMTD

Overview

The Fairchild Semiconductor 74ABT16500CMTD is an ABT series, 18-bit registered bus transceiver featuring true outputs. It utilizes a PDSO56 plastic package, specifically TSSOP-56. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 85°C. Key electrical characteristics include a maximum load capacitance of 50 pF and a maximum power supply current (ICC) of 68 mA. The component provides bidirectional data transfer with independent control capabilities.

Feature Summary

• Provides 18-bit registered bus transceiver functionality for high-density data handling
• Features true output polarity for direct signal interfacing
• Supports bidirectional data transfer with independent direction control
