MC74AC377NG

Flip Flops Overview

The MC74AC377NG is an octal D-type flip-flop from the onsemi 74AC logic series, housed in a 20-pin PDIP package. It operates within a supply voltage range of 2V to 6V and features non-inverting outputs with single-ended inputs. The device supports positive-edge triggering and includes a clock enable function. Key electrical specifications include a maximum propagation delay of 10ns at 5V with 50pF load, output currents of 24mA for both high and low states, and a static current of 8µA. It functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Positive-edge triggered operation synchronized by a common clock signal
• Clock enable functionality allowing selective data latching based on control input state
• CMOS construction ensuring low static power consumption and high noise immunity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations for data storage and transfer
• Register file architectures in digital processing systems
• Timing synchronization elements in sequential logic designs

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm RoHS compliance status and material composition declarations prior to integration. Check for obsolescence notices as this specific part number may be discontinued; validate current availability and lifecycle status with suppliers to ensure long-term project viability.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with clock enable is required in a through-hole DIP package. Ensure the design environment supports the 2V to 6V operating range and accommodates the specified propagation delay characteristics. Consider alternative surface-mount packages if PCB space constraints preclude the use of the 20-PDIP form factor.
