Product Overview: 74HC374PW by NXP
The 74HC374PW is a high-speed Si-gate CMOS device and a member of the 74HC family from NXP Semiconductors. This integrated circuit (IC) is characterized by its low power consumption and high noise immunity, typical of CMOS technology, while maintaining the speed of LSTTL (Low-Power Schottky Transistor-Transistor Logic).
Designed primarily as an octal D-type flip-flop, the 74HC374PW features eight edge-triggered, D-type flip-flops with 3-state outputs. These flip-flops capture the state of their individual D-inputs on the rising edge of the clock input. Once captured, the data is held in the flip-flop until the next rising edge. The 3-state outputs ensure that the IC can be used in bus-oriented systems; they can be placed in a high-impedance state, effectively disconnecting the output from the bus and allowing multiple devices to share the same connection lines.
Key Features:
- Logic Type: Octal D-type flip-flop with 3-state outputs
- Package: The 74HC374PW is housed in a TSSOP20 (Thin Shrink Small Outline Package), which offers a compact footprint suitable for space-constrained applications.
- Operating Voltage: It operates over a wide range of voltages, from 2.0V to 6.0V, making it versatile for various logic level requirements.
- Output Capability: Capable of driving up to 15 LSTTL loads.
- High Noise Immunity: Ensures stable operation in electrically noisy environments.
- Low Power Consumption: CMOS technology contributes to reduced power consumption, an essential feature for battery-powered and energy-efficient designs.
Applications:
The 74HC374PW is a versatile component that can be implemented in a wide range of applications, including:
- Buffer/Storage Registers
- Shift Registers
- Data Storage
- Communication Systems
- Microprocessor Systems
With its robust design and CMOS advantages, the 74HC374PW from NXP is a reliable choice for designers looking to implement flip-flops with 3-state outputs in their digital logic systems. Its compatibility with bus-oriented systems makes it particularly useful in complex digital circuits where multiple devices need to communicate over common data lines.
