Detailed Pin Configuration

The 74VHCT16373ATTR IC has a total of 48 pins, which are divided into four groups: 1. Group A (Pins 1-12): Data Inputs (D0-D11), Output Enable (OE), and Clock (CLK) inputs. 2. Group B (Pins 13-24): Data Inputs (D12-D23). 3. Group C (Pins 25-36): Data Inputs (D24-D35). 4. Group D (Pins 37-48): Data Inputs (D36-D47) and 3-State Outputs (Q0-Q15).

Functional Features

• 16-Bit Transparent D-Type Latch: The IC can store and latch 16 bits of data.
• 3-State Outputs: The outputs can be put in a high-impedance state, allowing multiple devices to share the same bus without interference.
• Output Enable (OE) Control: The OE input enables or disables the outputs.
• Clock (CLK) Input: The CLK input synchronizes the data transfer.

Advantages and Disadvantages

Advantages: - High-Speed Operation: The IC operates at a fast propagation delay time of 4.5ns, making it suitable for high-performance applications. - CMOS Technology: The use of CMOS technology provides low power consumption and wide voltage range compatibility. - 3-State Outputs: The ability to put the outputs in a high-impedance state allows for efficient bus sharing.

Disadvantages: - Limited Data Width: The IC can only store and latch 16 bits of data, which may not be sufficient for certain applications requiring larger data widths. - Package Size: The TSSOP package may be challenging to handle for some users due to its small size.

Working Principles

The 74VHCT16373ATTR is based on CMOS technology, which utilizes both NMOS and PMOS transistors to achieve low power consumption and high noise immunity. The IC functions as a transparent latch, allowing data to pass through when the latch enable signal (CLK) is active. The output enable signal (OE) controls the state of the outputs, enabling or disabling their functionality.
