M74HC273TTR

Flip Flops Overview

The M74HC273TTR is an octal D-type flip-flop with clear, fabricated using silicon gate C2MOS technology. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 66 MHz. The device features non-inverted outputs with high-level output current of -7.8 mA and low-level output current of 7.8 mA. Static current is limited to 4 µA. Propagation delay is specified at 25 ns under 6 V supply with 50 pF load. It functions across a temperature range of -55°C to +125°C and is housed in a 20-SOIC package.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific suffix matches the required package variant. Check RoHS compliance status against current regulatory requirements. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the obsolete status does not impact long-term project viability.

Flip Flops Selection Notes

Consider the M74HC273TTR for designs requiring octal storage with a global reset function. Evaluate the 66 MHz speed limit against system clock requirements. Assess power consumption needs given the 4 µA static current specification. Verify compatibility with existing PCB footprint constraints for the 20-SOIC package. Review replacement options if availability is critical for production continuity.
