74HC273D,653

Overview

The Nexperia 74HC273D,653 is an octal positive-edge triggered D-type flip-flop housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports a maximum clock frequency of 66 MHz. The device features eight independent D-type flip-flops with a common clock and master reset input. It exhibits low power dissipation and high noise immunity, complying with JEDEC standards for latch-up performance.

Feature Summary

• Octal configuration providing eight independent positive-edge triggered D-type flip-flops
• Common clock and master reset inputs for synchronized control
• Wide operating supply voltage range from 2.0 V to 6.0 V
• High noise immunity and robust latch-up performance exceeding 100 mA

Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Timing and state-holding logic in digital systems

Procurement Notes

Verify the specific suffix '653' corresponds to the SOIC-20 reel packaging format required for your assembly line. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to soldering profile selection. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical specification mismatches during integration.

Selection Notes

Select this component when an octal storage solution with a single shared clock is required. It is suitable for designs needing CMOS-level input compatibility and operation across a wide voltage spectrum. Consider the 20-SOIC package dimensions for PCB layout constraints and verify that the 66 MHz maximum frequency meets the system timing requirements.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard octal D-type flip-flops but offers specific packaging and electrical characteristics defined by the manufacturer. The device is designed for general-purpose digital logic applications requiring reliable data storage and transfer.

Replacement Considerations

Cross-reference with equivalent octal D-type flip-flops such as the 74HCT273 for TTL-compatible input levels if necessary. Verify pinout compatibility and electrical specifications against alternative manufacturers' offerings before substitution.
