SN74ALVCH374NG4 Octal Edge-Triggered D-Type Flip-Flops

The SN74ALVCH374NG4 from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit designed for use in a wide array of digital applications. This advanced device features eight D-type flip-flops with three-state outputs, making it ideal for bus-oriented applications.

Constructed using Texas Instruments' advanced BiCMOS technology, the SN74ALVCH374NG4 offers a compelling mix of speed and low power consumption. The device operates with a 2.5V to 3.6V V<sub>CC supply voltage, which ensures compatibility with low-voltage systems while maintaining the ability to interface with 5V components.

Each flip-flop is edge-triggered and updates the output based on the input state at the time of the rising edge of the clock signal. This precise timing control makes the SN74ALVCH374NG4 perfect for applications requiring synchronization, such as data storage, registers, or relay and buffer memory. Moreover, the flip-flops incorporate a clear function, which is synchronous to the clock input, allowing for the simultaneous clearing of all flip-flops under specific conditions.

The three-state outputs are crucial for bus-connected systems, allowing the outputs to go into a high-impedance state, effectively disconnecting the flip-flop from the bus. This feature prevents bus contention and allows for multiple devices to share the same bus lines without interference.

Key features of the SN74ALVCH374NG4 include:

• Operates from 2.5 V to 3.6 V
• High drive outputs (-24-mA IOH, 24-mA IOL)
• Edge-triggered D-type inputs
• Synchronous clear
• Three-state outputs for bus interfacing
• ESD protection exceeds JESD 22
• Latch-up performance exceeds 250 mA per JESD 17

This device is available in a 20-pin PDIP (Plastic Dual-In-line Package), ensuring easy integration into a variety of circuit boards. With its robust design and state-of-the-art performance, the SN74ALVCH374NG4 is a reliable choice for designers looking for a high-quality flip-flop IC to implement in their digital systems.
