SN74AHCT374DGVR

Flip Flops Overview

The SN74AHCT374DGVR is an octal D-type flip-flop from the Texas Instruments 74AHCT series, designed for high-speed CMOS applications with TTL-compatible inputs. It features eight non-inverting outputs with three-state control, housed in a 20-TFSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 130 MHz. Propagation delay is specified at 10.4 ns under standard conditions. It functions across an extended temperature range from -40°C to +85°C, providing robust performance for digital data storage and bus interface applications.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture with single clock input
• Three-state outputs allowing direct bus connection without external buffers
• TTL-compatible input logic levels ensuring interoperability with legacy systems
• High-speed operation supporting clock frequencies up to 130 MHz

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register files for microprocessor-based systems
• Bus-oriented memory mapping interfaces
• Timing synchronization and pulse holding applications

Flip Flops Procurement Notes

Verify the specific ordering suffix 'DGVR' to confirm the TVSOP-20 package and reel packaging configuration. Ensure compatibility with 5V logic systems due to AHCT input thresholds. Confirm RoHS compliance status as per current manufacturer documentation. Check for end-of-life notices, as this specific variant may have limited availability compared to standard tape-and-reel options.

Flip Flops Selection Notes

Select this component when an octal register with three-state output capability is required for 5V logic systems. It is suitable for designs needing TTL input compatibility alongside CMOS speed advantages. Consider the 20-TFSOP package dimensions for PCB layout constraints. Evaluate thermal requirements against the -40°C to +85°C operating range for industrial environments.

Flip Flops Part Context

This part belongs to the SN74AHCT374 family, which includes variants like SN74AHCT374DWR and SN74AHCT374PW. These components share identical logical functionality but differ in package types such as SOIC or TSSOP. The DGVR designation specifically indicates the thin-shrink small-outline package with reel packaging, distinguishing it from other physical form factors within the same logical series.

Flip Flops Replacement Considerations

SN74AHCT374DWR: Identical logical function in SOIC-20 package; verify pinout compatibility. SN74AHCT374PW: Nexperia equivalent in TSSOP-20 package; check footprint differences. SN74AHCT374QDGSRQ1: Automotive grade variant with extended temperature range; ensure qualification requirements match.
