The ON Semiconductor MC74ACT377 is a high-performance, octal D-type flip-flop integrated circuit, designed for use in a wide array of digital applications. This device features eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs control all flip-flops.

Key Features

• Logic Type: Octal D Flip-Flop
• Operating Voltage: 4.5V to 5.5V
• High-Speed Performance: tPD 4.5 ns (Typ) at VCC 5V
• Low Power Consumption: ICC 4 µA (Max) at TA 25°C
• Active State: Edge-triggered from LOW-to-HIGH transition
• Output Drive Capability: 24 mA at the outputs
• Temperature Range: -55°C to +125°C operating temperature range
• Package Options: Available in multiple package types, including SOIC and TSSOP

Product Description

The MC74ACT377 device is equipped with a clock enable (CE) function that allows the flip-flops to transition on a positive-going edge of the clock while the CE is asserted low. When CE is high, the flip-flops remain in their previous state, regardless of the clock input. This feature allows for greater flexibility in controlling the timing of data entry. The master reset (MR) input, when set to low, clears all flip-flops, setting the Q outputs to low, and this occurs regardless of the clock or clock enable inputs.

This ON Semiconductor product is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. The MC74ACT377 is fully compatible with ACT logic families and is designed to drive capacitive loads, such as memory address registers, data registers, and other high-capacitance loads, with ease.

Applications

With its robust feature set, the MC74ACT377 is ideal for a variety of applications, including:

• Memory data storage and retrieval
• Buffer registers
• Control registers
