74LV374D Octal D-Type Flip-Flop

The 74LV374D is a high-performance, low-voltage Si-gate CMOS device that is superior to most advanced CMOS compatible TTL families. Manufactured by NXP Semiconductors, this octal D-type flip-flop features 3-state non-inverting outputs for bus oriented applications.

The 74LV374D is part of the 74LV family, where LV stands for ‘low-voltage’. This means the device is optimized for operation at a nominal 3.3V supply voltage, with acceptable performance guaranteed between 2.0V and 3.6V, making it suitable for battery-operated and portable applications where power efficiency is key.

Each flip-flop has a 3-state output that provides a high impedance state, ensuring minimal power consumption when the device is not actively driving a load. The 3-state outputs also allow for direct connection to a bus-structured system without the need for interface or pull-up components.

The device features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously. The flip-flops will store the state of their individual D-inputs that meet the setup and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MR will reset the flip-flops, overriding the clock and data inputs.

The 74LV374D is packaged in a 20-pin SOIC (Small Outline Integrated Circuit) format, which is widely used and compatible with most PCB (Printed Circuit Board) design standards. Its low power consumption and high speed operation combined with true TTL compatibility makes it ideal for interfacing with microprocessors or microcontrollers in a wide range of electronic applications.

Key features of the 74LV374D include:

• Wide operating voltage range (2.0V to 3.6V)
• CMOS low power consumption
• Direct interface with TTL levels
• High impedance 3-state outputs
• Edge-triggered flip-flops
• Common clock and master reset
• Compliance with JEDEC standard no. 7A
• ESD protection:
• HBM JESD22-A114F exceeds 2000 V
• MM JESD22-A115-A exceeds 200 V
• Multiple package options

Overall, the 74LV374D is a versatile and reliable component for any design requiring a low-voltage, high-speed octal D-type flip-flop with 3-state outputs.
