NEXPERIA 74HCT245D Octal Bus Transceiver, SOIC-20

The NEXPERIA 74HCT245D is a high-speed octal bidirectional transceiver designed for interfacing and data transfer across bus systems. It features non-inverting three-state outputs compatible with both send and receive directions, making it a versatile component for digital circuits. An output enable input (OE) allows for easy cascading of multiple devices, while a direction control input (DIR) manages data flow, effectively isolating the buses when necessary.

This device is built using advanced silicon-gate CMOS technology, ensuring high-speed operation while maintaining pin compatibility with low-power Schottky TTL (LSTTL) logic families. It offers excellent electrical characteristics, including minimal input leakage and low quiescent current, contributing to efficient system power management.

Key Features & Specifications

• Octal Bidirectional Interface: Facilitates data transfer in both directions across an 8-bit bus.
• Non-Inverting 3-State Outputs: Provides bus-compatible outputs that can be placed in a high-impedance state.
• Direction Control: The DIR input determines the direction of data flow (A to B or B to A).
• Output Enable: The OE input disables the outputs, isolating the bus for safe sharing or cascading.
• Wide Operating Voltage: Supports a supply voltage range from 4.5V to 5.5V.
• Extended Temperature Range: Operational from -40°C to 125°C, suitable for industrial environments.
• Low Power Consumption: Features very low input leakage current (±0.1μA), off-state output current (±0.5μA), and quiescent supply current (8μA).
• Industry Standard Compliance: Conforms to JEDEC standard number 7A.
• Compact Package: Housed in a space-saving SOIC-20 surface-mount package.

Important Handling Note: This is an ESD-sensitive device. Proper electrostatic discharge precautions must be taken during handling and
