SN74HCS72DR

Flip Flops Overview

The SN74HCS72DR is a dual D-type flip-flop from Texas Instruments' High-Speed CMOS (HCS) logic family. It features Schmitt-trigger inputs for noise immunity and push-pull outputs capable of driving 7.8 mA at both high and low states. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 105 MHz. Propagation delay is specified at 7 ns, with an operating temperature range spanning from -40°C to +125°C. It is housed in a 14-pin SOIC package.

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package type and tape/reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the active status on official distributor platforms to avoid obsolete stock. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Flip Flops Selection Notes

Select this component when dual independent D-type storage with input hysteresis is required. The HCS series offers faster switching speeds compared to standard HC logic while maintaining low power consumption. Consider the 14-pin SOIC footprint for PCB layout constraints. Verify that the 105 MHz maximum clock frequency aligns with system timing requirements before finalizing the design.

Flip Flops Part Context

This part belongs to the SN74HCSxx series, designed as a high-speed alternative to traditional 74HC logic. It integrates Schmitt-trigger functionality directly into the flip-flop inputs, distinguishing it from basic D-type variants. The DR suffix indicates surface-mount packaging suitable for automated assembly processes common in modern electronics manufacturing.

Flip Flops FAQ

Does the SN74HCS72DR include individual reset pins for each flip-flop?

No, the SN74HCS72DR does not feature dedicated reset pins. It relies on the D and CLK inputs for state control without asynchronous or synchronous reset functionality.

What is the significance of the Schmitt-trigger inputs in this device?

The Schmitt-trigger inputs provide hysteresis, which filters out noise and ensures clean signal transitions even with slow-rising input edges, improving reliability in noisy environments.
