MC74HCT273ADTR2G

Flip Flops Overview

The MC74HCT273ADTR2G is an octal D-type flip-flop from the HCT logic series, manufactured by onsemi. It features a single circuit with eight non-inverting outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a maximum propagation delay of 25 ns at 5 V with 50 pF load and supports a clock frequency of 30 MHz. Static current consumption is limited to 4 µA. It is housed in a 20-TSSOP package with a width of 4.40 mm, designed for surface mount installation across an operating temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Octal D-type configuration providing eight independent data storage elements within a single integrated circuit.
• HCT logic compatibility ensures direct interface with standard TTL inputs while maintaining CMOS low power characteristics.
• Positive-edge triggering mechanism synchronizes data input to the clock signal for precise timing control.
• Non-inverting output polarity maintains logical consistency between input data states and stored output values.

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring stable latching capabilities
• General-purpose register arrays for temporary data storage in digital systems
• Shift register configurations for serial data transmission processing
• Timing synchronization modules in microcontroller peripheral interfaces

Flip Flops Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) prior to assembly. Ensure soldering profiles align with TSSOP-20 thermal requirements. Cross-reference datasheet specifications against system design constraints to validate electrical performance under intended operating conditions.

Flip Flops Selection Notes

Select this component when interfacing with TTL-level signals using CMOS technology is required. The HCT series offers superior noise immunity compared to standard HC variants. Consider the 20-TSSOP package for space-constrained surface-mount designs. Evaluate the 25 ns propagation delay against system timing budgets to ensure adequate setup and hold times are met during high-speed operation.

Flip Flops Part Context

This part belongs to the MC74HCT273A family of octal D-type flip-flops. It shares functional similarities with other members like MC74HCT273ADWR2G but differs in packaging. The TSSOP variant provides a compact footprint suitable for dense PCB layouts. It complements onsemi's broader portfolio of logic ICs targeting industrial and consumer applications requiring reliable sequential logic functions.

Flip Flops Replacement Considerations

MM74HCT273MTCX serves as a documented substitute option within the same logic family. Verify pinout compatibility and electrical parameters before implementation. Alternative packages such as SOIC-20 variants may require mechanical adaptation. Ensure replacement parts meet identical voltage and temperature specifications for seamless integration.
