SN74ALVCH374DBR

Flip Flops Overview

The SN74ALVCH374DBR is an octal D-type flip-flop from Texas Instruments' ALVCH series, housed in a 20-pin SSOP package. It operates on a single supply voltage ranging from 1.65 V to 3.6 V. The device features positive-edge triggering and three-state outputs for bus-oriented memory mapping and driving. Key electrical specifications include a maximum propagation delay of 3.6 ns at 3.3 V with a 50 pF load, and output drive capabilities of ±24 mA. It supports CMOS and LVTTL input levels, ensuring compatibility across various logic families within the specified voltage range.

Flip Flops Feature Summary

• Provides eight independent D-type flip-flops with positive-edge clock triggering for data storage applications.
• Features three-state outputs that facilitate direct connection to system buses without additional interface hardware.
• Supports low-voltage operation from 1.65 V to 3.6 V, enabling compatibility with modern low-power digital systems.
• Accepts both CMOS and LVTTL input signals, allowing flexible interfacing with diverse logic standards.

Flip Flops Applications

• Bus-oriented memory register implementations
• 8-bit position counters in industrial control systems
• Parallel-to-serial data conversion circuits

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 tape-and-reel packaging configuration required for automated assembly processes. Confirm that the operating voltage range of 1.65 V to 3.6 V aligns with the target system's power rails. Ensure thermal management considerations are addressed for the SSOP package within the designated ambient temperature range of -40°C to +85°C during design validation.

Flip Flops Selection Notes

Select this component when designing systems requiring octal latching with three-state bus isolation at low voltages. It is suitable for applications needing high-speed data transfer with propagation delays as low as 3.6 ns. Consider alternative packages like DW or PWR if pin count or footprint constraints differ. Evaluate current drive requirements against the ±24 mA capability to ensure adequate fan-out for connected loads.

Flip Flops Part Context

This part belongs to the SN74ALVCH374 family of octal D-type flip-flops. It shares functional similarities with other members like SN74ALVCH374DW but differs in packaging and reel specifications. The ALVCH series is designed for low-voltage applications, distinguishing it from standard 5 V HC or AC logic families. It serves as a key component in memory and buffering architectures where voltage translation and bus holding are critical.

Flip Flops Replacement Considerations

SN74ALVCH374DW (SOIC-20 tube), SN74ALVCH374PWR (TSSOP-20 reel). Verify pinout compatibility and thermal performance differences between SSOP, SOIC, and TSSOP packages before substitution.

Flip Flops FAQ

What is the maximum propagation delay for the SN74ALVCH374DBR?
