Product Overview: CD74HCT377E by Texas Instruments

The CD74HCT377E is a high-performance, CMOS logic octal D-type flip-flop with clock enable, manufactured by the renowned semiconductor company, Texas Instruments. This integrated circuit is designed for use in a wide range of digital applications where the storage of eight bits of data is required. It is a member of the HCT family which means it is designed to meet the electrical specifications of the TTL logic family while maintaining the low power consumption and high noise immunity typical of CMOS devices.

The device features eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs control all flip-flops. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MR causes all flip-flops to reset, overriding all other inputs. The clock enable (CE) input must be at a LOW level to allow the flip-flops to toggle; a HIGH level on CE locks the flip-flops in their current state.

The CD74HCT377E has a wide operating voltage range from 4.5V to 5.5V, making it compatible with standard TTL operating voltages, and it can operate in temperatures ranging from -55°C to 125°C. This makes it suitable for use in harsh environments and ensures reliable performance in a variety of applications, including industrial, automotive, and consumer electronics.

Available in a standard 20-pin DIP (Dual In-line Package), the CD74HCT377E is easy to implement in a broad array of PCB layouts. It is also characterized for operation from -55°C to 125°C, ensuring its reliability in extreme conditions. The device's inputs are TTL-compatible which allows for direct interfacing with TTL logic levels with minimal power consumption.

In summary, the CD74HCT377E from Texas Instruments is a versatile and reliable component for storing and managing digital data. Its compatibility with the TTL logic family, combined with the low power requirements of CMOS technology, makes it a practical choice for designers looking to optimize their digital systems.
