74HCT377PW,118

Overview

The Nexperia 74HCT377PW,118 is an octal D-type flip-flop with data enable and positive-edge triggering. It operates within a supply voltage range of 4.5V to 5.5V. The device features a maximum clock frequency of 53 MHz and a propagation delay of 32ns at 4.5V with 50pF load capacitance. It provides 4mA output high current and 5.2mA output low current, with a static current of 8µA. Packaged in a 20-TSSOP (4.40mm wide), it supports surface mount installation and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Octal D-type flip-flop architecture with dedicated data enable control
• Positive-edge triggered operation for synchronous data capture
• Non-inverting outputs suitable for bus-oriented applications

Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor systems
• Data buffering and storage in digital logic designs

Procurement Notes

Verify the specific suffix '118' corresponds to the TSSOP-20 package and standard commercial grade when sourcing. Confirm RoHS compliance status matches REACH requirements for your region. Ensure the distributor source aligns with Nexperia authorized channels to guarantee component authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when TTL-compatible input levels are required alongside CMOS performance characteristics. The HCT series ensures compatibility with standard 5V logic families. Consider the 20-TSSOP package dimensions for PCB layout constraints. Verify that the 53 MHz maximum frequency meets the system clock requirements for the intended application speed.

Part Context

This part belongs to the 74HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. It is part of the broader 74-series logic portfolio used in general-purpose digital electronics. The 377 variant specifically provides eight independent D-type flip-flops, offering efficient space utilization compared to discrete single-bit solutions in complex integrated circuits.

Replacement Considerations

The 74HCT377PW-Q100J is documented as a parameter-equivalent substitute. This alternative offers automotive qualification under AEC-Q100 standards while maintaining functional compatibility with the standard industrial grade version.
