ON Semiconductor MC74HC374ADTG Octal D-Type Flip-Flop

The MC74HC374ADTG from ON Semiconductor is a high-performance, octal D-type flip-flop integrated circuit designed for use in a wide range of digital applications. This device features eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The 3-state outputs are designed to offer both high-impedance 'off' state and active 'on' state, which allows for the direct connection of multiple outputs to a common bus line without the need for interface or pull-up components.

Constructed with silicon gate CMOS technology, the MC74HC374ADTG ensures low power consumption and a broad operating voltage range from 2V to 6V. This makes it an ideal choice for interfacing with both standard CMOS and LSTTL logic levels, providing the versatility needed for a variety of digital systems.

The device features a non-inverting data path, where the data presented at the D inputs is captured on the rising edge of the clock signal (CLK) and held at the outputs until the next rising edge. A buffered output enable (OE) input can be used to place the eight outputs in either a normal logic state or the high-impedance state, thus enabling the outputs to be disabled and preventing any potential bus conflict.

Key features of the MC74HC374ADTG include:

• Eight D-type flip-flops with single clock and output enable inputs
• 3-state outputs for bus-oriented applications
• Wide operating voltage range of 2V to 6V
• Low input current of 1µA max
• High noise immunity characteristic of CMOS devices
• In compliance with the JEDEC standard no. 7A requirements
• ESD performance: HBM > 2000V; MM > 200V
• Offered in TSSOP−20 package for reduced space requirements

With its robust design and reliable performance, the MC74HC374ADTG is suitable for a broad range of applications, such as memory address latching, data storage, buffer registers, and control registers. Its industry-standard packaging and pinout make it easy to integrate into existing designs, providing designers with a flexible and efficient solution for their digital logic needs.
