SN74AHCT374DW

Flip Flops Overview

The SN74AHCT374DW is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the AHCT logic series. It features eight independent D-type flip-flops with tri-state outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-compatible input levels. Key electrical specifications include a propagation delay of 10.4 ns, with output current capabilities of -8 mA at high level and 8 mA at low level. It is housed in a SOIC-20 surface-mount package and supports a standard operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight edge-triggered D-type flip-flops with tri-state outputs for efficient data storage and bus interfacing.
• Ensures compatibility with TTL logic systems through dedicated input structures while maintaining CMOS performance characteristics.
• Provides controlled signal transitions via tri-state outputs to facilitate direct connection to system buses without external drivers.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register files and buffer stages in microprocessor-based systems
• I/O port expansion for digital control interfaces

Flip Flops Procurement Notes

Verify that the component matches the exact SN74AHCT374DW designation to ensure correct logic family and package type. Confirm RoHS compliance status as indicated in official documentation. Check for any specific handling requirements related to moisture sensitivity during storage and reflow soldering processes. Ensure supplier documentation aligns with Texas Instruments manufacturing standards for quality assurance.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed CMOS performance in a 20-pin surface-mount format. Consider the 10.4 ns propagation delay and 8 mA drive capability against system timing and load requirements. Evaluate the SOIC-20 package dimensions for PCB layout constraints compared to alternative packages like TSSOP or PDIP if space is limited.

Flip Flops Part Context

This part belongs to the SN74AHCT374 series, which includes variants such as SN74AHCT374PW (TSSOP) and SN74AHCT374N (PDIP). These variations share identical logical functionality but differ in physical packaging and mounting style. The DW suffix specifically denotes the small-outline integrated circuit (SOIC) package with a 20-lead configuration suitable for automated surface-mount assembly.

Flip Flops Replacement Considerations

SN74AHCT374PW serves as a pin-compatible alternative offering the same logical function in a TSSOP-20 package. SN74AHCT374N provides a through-hole option for prototyping or legacy board designs. Substitution requires verification of thermal performance and mechanical fit within the existing footprint.
