Functional Features
- The PI74LCX16374AE is a 16-bit D-type transparent latch with 3-state outputs.
- It operates at low voltage levels, making it suitable for use in battery-powered devices.
- The latch allows data to be transferred from the input (D) to the output (Q) when the clock signal (CP) is active.
- The output enable (OE#) pin controls the tri-state outputs, allowing them to be disabled when not needed.
Advantages and Disadvantages
Advantages: - Low voltage operation extends battery life in portable devices. - High-speed operation enables efficient data transfer. - 3-state outputs provide flexibility in connecting multiple devices.
Disadvantages: - Limited supply voltage range may restrict compatibility with certain systems. - Higher cost compared to some alternative models.
Working Principles
The PI74LCX16374AE works based on the principles of flip-flop latches and 3-state logic. When the clock signal (CP) is active, the latch transfers the data from the input (D) to the output (Q). The output enable (OE#) pin controls whether the outputs are enabled or disabled. When disabled, the outputs enter a high-impedance state, allowing other devices to drive the bus.
Detailed Application Field Plans
The PI74LCX16374AE is commonly used in various applications, including: - Data communication systems - Networking equipment - Industrial control systems - Portable electronic devices - Automotive electronics
