SN74HCT74NG4

Flip Flops Overview

The SN74HCT74NG4 is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. It features independent clear and preset inputs for direct control of the output state. The device operates within a supply voltage range of 2V to 6V and supports data rates up to 37 MHz at 5V. It is housed in a 14-pin DIP package and functions reliably across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Dual configuration containing two independent D-type flip-flops with positive-edge triggering.
• Includes dedicated asynchronous clear and preset inputs for immediate output state control.
• CMOS technology ensures low static power consumption and high noise immunity.
• Compatible with standard TTL logic levels for direct interfacing.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Digital timing and sequencing logic
• Memory address latching

Flip Flops Procurement Notes

Verify that the ordering suffix 'G4' corresponds to lead-free, RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm the package type matches the required DIP-14 footprint for your PCB layout. Ensure the supply voltage provided to the circuit remains within the specified 2V to 6V operational limits to maintain signal integrity and prevent device damage.

Flip Flops Selection Notes

Select this component when a dual flip-flop solution with separate clear and preset controls is required. The HCT series is appropriate for systems utilizing 5V TTL logic levels. Consider the DIP-14 package if through-hole mounting is necessary. Verify that the maximum clock frequency requirements of the application fall within the device's specified switching speed capabilities under the intended load conditions.

Flip Flops Part Context

This part belongs to the SN74HCT family of high-speed CMOS logic devices from Texas Instruments. The HCT series is designed to be compatible with standard 5V TTL inputs while offering the lower power consumption typical of CMOS technology. The '74' designation indicates a dual D-type flip-flop function, and the 'N' suffix specifies the plastic dual-in-line package style.

Flip Flops Replacement Considerations

The SN74HCT74NSR is a surface-mount alternative with identical electrical characteristics but in a SOIC package. For pin-compatible replacements, verify that any substitute maintains the same HCT logic level compatibility and package dimensions. Cross-reference datasheets to ensure functional equivalence regarding clear and preset operations.
