Product Overview: 74HC374D by NXP

The 74HC374D is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, a leader in the electronic components industry, this product is part of the 74HC family, which is well-known for its robustness and versatility in various digital applications.

This particular integrated circuit is an octal D-type flip-flop with 3-state outputs. It is designed to have eight edge-triggered, D-type flip-flops with individual D inputs and O outputs. The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously. The 3-state outputs are controlled by the output enable input (OE). When OE is low, the outputs are active and reflect the data that was set at the last rising edge of CP. When OE is high, the outputs are in a high impedance 'off' state, which is particularly useful for interfacing with bus-structured systems.

The 74HC374D comes in a standard SO20 package, which is suitable for surface-mounted technology (SMT) and is widely used in modern electronic circuit designs. The device can operate across a wide voltage range from 2.0 to 6.0 V and features low input current of 1 μA max, making it an excellent choice for battery-powered and low-power applications.

Key features of the 74HC374D include:

• Octal D-type flip-flop with 3-state outputs
• Common clock and master reset
• Wide operating voltage range of 2.0 to 6.0 V
• Low power consumption: ICC = 4 μA max (at TA = 25°C)
• High noise immunity
• Complies with JEDEC standard no. 7A
• ESD protection:
  • HBM JESD22-A114E exceeds 2000 V
  • MM JESD22-A115-A exceeds 200 V
• Multiple package options

Applications for the 74HC374D are varied and include buffer storage, register storage, shift registers, and as part of the data bus interface. Its reliability and performance make it a go-to component for engineers and designers looking to build sophisticated digital systems.
