Flip Flops datasheet and documents for SN74ALS574BNG4

SN74ALS574BNG4

Flip Flops Overview

The SN74ALS574BNG4 is an octal D-type edge-triggered flip-flop with three-state outputs belonging to the Texas Instruments ALS logic series. It features a non-inverting configuration and accepts TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting a propagation delay of 14 ns. It provides a low-level output current of 24 mA and a high-level output current of -2.6 mA. Designed for through-hole mounting, it is housed in a PDIP-20 package and functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

Octal D-type edge-triggered flip-flop architecture with three-state outputs
Non-inverting polarity with TTL input compatibility
High drive capability with 24 mA low-level output current

Flip Flops Applications

Parallel data storage and buffering in digital systems
Interface circuits requiring tri-state isolation
Register arrays in microprocessor-based designs

Flip Flops Procurement Notes

Verify the G4 suffix indicates lead-free composition and RoHS compliance per manufacturer specifications. Confirm the PDIP-20 package matches PCB footprint requirements. Ensure the ALS series electrical characteristics align with existing system timing and voltage levels before integration.

Flip Flops Selection Notes

Select this component when octal storage with tri-state control is required in through-hole applications. The ALS series offers improved speed over standard 74LS equivalents while maintaining compatible pinouts. Verify that the 14 ns propagation delay meets system clock constraints and that the 24 mA sink current suffices for load requirements.

Flip Flops Part Context

This part belongs to the SN74ALS574B family of octal flip-flops. The 'G4' suffix typically denotes environmental compliance, specifically lead-free construction and adherence to RoHS directives. It shares functional equivalence with other variants in the ALS series but differs in packaging or environmental certification details.
