The 74HC244BQ is a high-performance, octal buffer and line driver designed to operate at 2V to 6V VCC operation. Manufactured by NXP Semiconductors, this integrated circuit is part of their 74HC (High-Speed CMOS) family, offering the robustness and speed of CMOS technology with the added benefit of interfacing with TTL levels.

Key Features

• Voltage Range: The device is versatile, with a broad VCC operating range from 2.0V to 6.0V, making it suitable for various applications and logic level integrations.
• High Noise Immunity: Incorporates high noise immunity characteristics inherent to CMOS technology, ensuring stable operation in electrically noisy environments.
• Low Power Consumption: Features a balanced propagation delay and transition times, contributing to its low power consumption while maintaining high-speed operation.
• Multiple Configurations: The 74HC244BQ provides two sets of four buffers with separate output-enable (OE) inputs, allowing flexible control over signal transmission.
• Non-Inverting Buffers: The device consists of non-inverting buffers, which means the output signal is the same as the input signal, provided the output is enabled.
• Pin Compatibility: It is pin-compatible with the Low-power Schottky TTL (LSTTL), ensuring ease of integration into existing designs.
• Compliance: This product is specified in compliance with JEDEC standard no. 7A and is available in a DHVQFN20 package.
