SN74HC273DBR

Flip Flops Overview

The SN74HC273DBR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic family. It features eight independent positive-edge-triggered D-type flip-flops with a common clock (CP) and master reset (MR). The device operates within a supply voltage range of 2 V to 6 V and supports through-hole or surface-mount installation depending on the specific variant configuration, though the DBR suffix typically denotes a SOIC package. Key electrical parameters include a propagation delay of 160 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It functions reliably across a temperature range of -40°C to +85°C.

Flip Flops Procurement Notes

Verify the exact package type against the manufacturer datasheet, as suffixes can vary by region and revision. Confirm RoHS compliance status for environmental regulations. Ensure the operating voltage range matches your system requirements before integration. Check for alternative pin-compatible packages if PCB layout constraints require different form factors.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements with a single control line. The HC series offers a balance of speed and power consumption suitable for general-purpose digital logic. Consider the propagation delay specifications for timing-critical applications. Evaluate thermal performance if operating near the maximum temperature limits.

Flip Flops Part Context

This part belongs to the widely adopted 74HC logic family, known for high-speed CMOS operation. It serves as a fundamental building block in digital electronics for data storage and transfer.

Flip Flops FAQ

How does the master reset function operate?

When the master reset input is low, all outputs are forced to a low state regardless of the clock or data input states.

What is the typical static current consumption?

The static current is typically very low, often in the microampere range, making it suitable for battery-powered applications.
