74HC377DB,118

Overview

The 74HC377DB,118 is an octal D-type flip-flop with data enable and positive-edge trigger, manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and features single-ended inputs and outputs. The device is housed in a 20-pin SSOP package (SOT339-1) and supports a maximum operating frequency of 18 MHz at nominal supply. It includes hold mode functionality and exhibits low static current consumption. The component is rated for operation between -40 °C and +125 °C, complies with RoHS standards, and meets JEDEC JESD7A specifications for high noise immunity.

Feature Summary

• Octal D-type flip-flop architecture with dedicated data enable input
• Positive-edge triggering mechanism for synchronous data capture
• Single-ended non-inverting output configuration
• Hold mode capability for state retention

Applications

• Bus-oriented data storage applications
• Parallel-to-serial data conversion circuits
• Digital signal processing interface modules
• Memory address latching systems

Procurement Notes

Verify the specific ordering code 74HC377DB,118 against official Nexperia documentation to confirm package type and electrical characteristics. Ensure compatibility with system voltage requirements ranging from 2.0 V to 6.0 V. Confirm that the SSOP20 package dimensions align with PCB layout constraints. Check for any recent product change notifications regarding assembly sites or labeling updates.

Selection Notes

Select this component when an octal D-type flip-flop with data enable is required for high-noise environments. The HC series offers CMOS-level input compatibility and wide supply voltage flexibility. Consider the 18 MHz maximum frequency limit for clock speed requirements. Verify thermal performance within the specified -40 °C to +125 °C operating range for industrial applications.

Part Context

This part belongs to the 74HC(T)377 family of octal D-type flip-flops. It shares functional similarities with other logic families but is distinguished by its HC technology, which provides CMOS input levels and low power dissipation. The DB suffix indicates the SSOP20 package variant, differentiating it from TSSOP or SO variants within the same logical function set.

Replacement Considerations

The 74HC377PW,118 serves as a parameter-equivalent alternative with a TSSOP20 package. Verify pinout compatibility and package dimensional differences before substitution. Other family members like 74HCT377 offer TTL input levels instead of CMOS.
