SN74ALVCH374DWR by Texas Instruments

The SN74ALVCH374DWR is a high-performance, octal edge-triggered D-type flip-flop with 3-state outputs from Texas Instruments. This integrated circuit is designed to deliver the functionality required for a wide range of digital applications, particularly where high speed, low power consumption, and reduced noise are essential.

This device is part of the advanced low-voltage CMOS (ALVC) family, which operates on a 3.3V power supply while maintaining 5V tolerant inputs. The SN74ALVCH374DWR is capable of interfacing with 5V components without the need for additional level shifting, making it a versatile choice for mixed-voltage systems. The 3-state outputs allow for connection to a bus-organized system, providing high-impedance states to ensure minimal loading when the outputs are not in use.

Each flip-flop is edge-triggered, capturing data on the rising edge of the clock signal, which provides precise timing control for synchronous data transfer. The device also features a clear function, which can be used to reset all flip-flops to a low state, ensuring a predictable starting condition upon initialization or after an error state.

The SN74ALVCH374DWR comes in a wide-body SOIC (Small Outline Integrated Circuit) package, with the suffix 'DWR' indicating the tape and reel packaging option for automated assembly processes. This component is designed for surface-mount technology (SMT), allowing for compact and efficient PCB (Printed Circuit Board) designs.

Key features of the SN74ALVCH374DWR include:

• Eight edge-triggered D-type flip-flops with 3-state outputs
• Operating voltage range of 2.3V to 3.6V with 5V tolerant inputs
• Maximum operating frequency: 250 MHz (typical)
• Low power consumption with ICC reduced by 50%
• ESD protection exceeds JESD 22
• Supports live insertion and withdrawal (partial-power-down mode)
• Latch-up performance exceeds 250 mA per JESD 17

The SN74ALVCH374DWR is ideal for applications such as memory address latching, data storage, and communication systems that require high-speed, reliable data transfer with minimal power draw. Its robust design and advanced features make it a smart choice for engineers and designers looking to enhance their digital systems.
