SN74LS273N

Flip Flops Overview

The SN74LS273N is an octal D-type flip-flop manufactured by Texas Instruments in the LS logic family. It features eight non-inverting outputs triggered on the positive edge of the clock signal and includes a master reset input. The device operates within a supply voltage range of 4.75V to 5.25V, with a maximum propagation delay of 27ns at 5V and a clock frequency up to 30MHz. It utilizes a 20-pin PDIP package and supports through-hole mounting.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops providing one-bit storage per element
• Positive-edge triggering mechanism for data capture synchronized with clock signals
• Master reset functionality allows simultaneous clearing of all outputs

Flip Flops Applications

• Data storage registers in digital systems
• Shift register configurations
• Counter circuits

Flip Flops Procurement Notes

Verify that the component matches the specific SN74LS273N designation rather than variants such as NSR or NE4. Confirm the manufacturer is Texas Instruments and check the datasheet for current production status. Ensure the 20-pin PDIP package aligns with the target PCB footprint requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing TTL-compatible circuits requiring octal storage with positive-edge triggering. Consider the 27ns propagation delay and 8mA output drive capability against system timing constraints. Verify that the 4.75V to 5.25V operating voltage range fits the available power supply infrastructure.

Flip Flops Part Context
