The SN74HCT374M is a high-performance, octal edge-triggered D-type flip-flop integrated circuit from Texas Instruments, designed to operate as a memory storage device for 8-bit wide data. It is a significant component in digital systems, particularly useful in applications that require the capture and storage of data lines simultaneously.

Key Features

• Logic Family: HCT (High-Speed CMOS, TTL-Compatible)
• Package: SOIC-20 (Small Outline Integrated Circuit)
• Operating Voltage: 4.5V to 5.5V, making it compatible with TTL logic levels.
• Output Drive Capability: Capable of driving 15 LSTTL loads.
• Speed: Fast propagation delays and high-current 3-state outputs that sink 24mA and source 24mA.
• Temperature Range: Specified for operation from -40°C to 85°C.

Functional Description

The SN74HCT374M device features eight D-type flip-flops with 3-state outputs. The flip-flops capture the state of their individual D-inputs on the rising edge of the clock (CLK) input. Once captured, the data is held stable at the output until the next rising edge of the CLK signal. The 3-state outputs ensure that the device can be used in bus-oriented systems. The output enable (OE\) input can be used to place the eight outputs in either a normal logic state or a high-impedance state, thereby allowing the outputs to effectively disconnect from the bus for multiple device sharing.

Applications

With its robust design and versatile functionality, the SN74HCT374M is ideal for a wide range of applications, including:

• Buffer/Storage Registers
• Shift Registers
• Data Storage
• Pattern Generators
• Industrial Control Systems
