The HD74HC354P is an 8-input data selector/multiplexer with 3-state outputs manufactured by Hitachi. This high-speed CMOS device is part of the 74HC family, offering improved performance and lower power consumption compared to traditional TTL logic. It allows selecting one of eight data inputs and routing it to the output, controlled by a 3-bit address input.

Applications:

• Data selection and multiplexing
• Logic function generation
• Parallel-to-serial data conversion
• Address multiplexing for memory systems
• Digital audio and video routing

Features:

• 8-input data selector/multiplexer
• 3-state outputs for bus applications
• High-speed CMOS technology
• Low power consumption
• Wide operating voltage range
• Compatible with TTL logic levels

Benefits:

• Efficient data selection and routing
• Reduced component count in multiplexing applications

• Lower power consumption for battery-powered devices
• Flexible interface with various logic families

The HD74HC354P operates by selecting one of its eight data inputs (D0-D7) based on the 3-bit address input (A0-A2). The selected input is then routed to the output (Y). The device also features an Output Enable (OE) input, which, when high, forces the output to a high-impedance state. This 3-state output capability allows multiple devices to share a common bus without contention. The device's high-speed CMOS technology ensures fast switching speeds and low power dissipation, making it suitable for a wide range of applications.
