SN74AHC16373DGVR

Product Overview

• Category: Integrated Circuit (IC)
• Use: Digital Logic
• Characteristics: 16-bit Transparent D-Type Latches with 3-State Outputs
• Package: TSSOP (Thin Shrink Small Outline Package)
• Essence: This IC is a latch that can store and output 16 bits of digital data. It features a transparent input, which means the data at the input is directly transferred to the output when the latch is enabled.
• Packaging/Quantity: The SN74AHC16373DGVR is typically sold in reels containing 2500 units.

Specifications

• Number of Bits: 16
• Logic Family: AHC (Advanced High-Speed CMOS)
• Output Type: 3-State
• Supply Voltage Range: 2V to 5.5V
• Operating Temperature Range: -40°C to 85°C
• Input/Output Compatibility: TTL, CMOS

Detailed Pin Configuration

The SN74AHC16373DGVR has a total of 48 pins, which are divided into various functional groups:

• Latch Inputs (D0-D15): These pins are used to input the 16 bits of data to be stored in the latch.
• Latch Enable (LE): This pin enables or disables the latch operation. When LE is high, the latch is transparent, allowing the data at the inputs to pass through to the outputs. When LE is low, the latch holds the previously stored data.
• Output Enable (OE): This pin controls the output state of the latch. When OE is high, the outputs are in a high-impedance state (disconnected). When OE is low, the outputs reflect the data stored in the latch.
• Outputs (Q0-Q15): These pins provide the 16-bit output data.

Functional Features

• Transparent input allows real-time data transfer to the outputs.
• 3-state outputs provide flexibility in connecting multiple devices together.
• Wide supply voltage range enables compatibility with various systems.
• High-speed operation suitable for time-critical applications.
• Low power consumption.

Advantages and Disadvantages

Advantages: - Real-time data transfer capability. - Flexible output configuration. - Wide supply voltage range. - High-speed operation. - Low power consumption.

Disadvantages: - Limited number of bits (16). - Requires external control signals (LE and OE) for proper operation.

Working Principles

The SN74AHC16373DGVR operates based on the principles of digital logic. When the latch enable (LE) signal is high, the latch becomes transparent, allowing the data at the inputs to pass through to the outputs. The output enable (OE) signal controls whether the outputs are active or in a high-impedance state. By manipulating these control signals, the user can store and retrieve data from the latch.

Detailed Application Field Plans

The SN74AHC16373DGVR can be used in various applications that require storage and retrieval of digital data. Some potential application fields include:

1. Microcontrollers: The latch can be used to store temporary data during microcontroller operations, such as buffering input/output data or storing intermediate results.
2. Data Communication Systems: The latch can be utilized in data communication systems to hold data packets temporarily before transmission or after reception.
3. Memory Systems: The latch can be employed in memory systems to buffer data during read/write operations, ensuring stable and reliable data transfer.

Detailed and Complete Alternative Models

1. SN74AHC16373DGV: Similar to SN74AHC16373DGVR, but available in a different package (TSSOP-48).
2. MC74AHC16373: Equivalent latch from a different manufacturer (Motorola).
3. CD74AHC16373: Equivalent latch from another manufacturer (Texas Instruments).

These alternative models provide similar functionality and can be used as substitutes for the SN74AHC16373DGVR, depending on specific requirements and availability.
