SN74HC74AN

Flip Flops Overview

The SN74HC74AN is a dual D-type flip-flop from the Texas Instruments SN74HC series, housed in a 14-pin PDIP package. It features positive-edge triggering with independent clear and preset inputs. The device operates on a single power supply ranging from 2 V to 6 V. Key electrical parameters include a propagation delay of 32 ns at 5 V, a maximum clock frequency of 32 MHz, and output drive capabilities of ±5.2 mA. It supports through-hole mounting and functions within an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type flip-flops with dedicated asynchronous clear and preset controls
• Positive-edge triggered data capture synchronized with clock input
• Three-state outputs allowing direct bus line interfacing

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage
• General-purpose digital logic state retention

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and environmental compliance. Confirm that the procurement channel provides original manufacturer packaging to prevent counterfeit components. Cross-reference the date code with the latest production status to ensure availability and consistency with design specifications.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with separate control inputs is required in a through-hole design. The HC series offers CMOS compatibility with TTL voltage levels. Ensure the application voltage remains within the 2 V to 6 V range to maintain specified switching speeds and noise margins. Consider the PDIP package constraints for PCB layout and thermal management.

Flip Flops Part Context

This part belongs to the widely adopted SN74HC family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic designs. The 'AN' suffix denotes the standard plastic dual-in-line package variant manufactured by Texas Instruments, ensuring broad compatibility with legacy DIP-based systems.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include the SN74HC74N and SN74HCT74N. Verify voltage level compatibility if replacing with HCT variants, as they require strict 5 V operation. Check datasheets for any differences in switching characteristics or package dimensions before finalizing the substitution.
