Flip Flops datasheet and documents for SN74AS821ANT

SN74AS821ANT

Flip Flops Overview

The SN74AS821ANT is a bipolar bus interface flip-flop from the Texas Instruments 74AS series. It integrates ten D-type flip-flops with three-state outputs in a single circuit, housed in a 24-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports non-inverting TTL inputs. Key electrical characteristics include a propagation delay of 6.2 ns, a high-level output current of -24 mA, and a low-level output current of 48 mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm the specific suffix 'ANT' corresponds to the 24-pin PDIP tube packaging variant. Ensure compatibility with existing 5V logic levels and thermal management requirements for the specified operating temperature range before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed parallel data storage with bus isolation capabilities. The bipolar technology offers superior drive strength compared to CMOS alternatives, making it suitable for driving heavy capacitive loads on data buses. Consider the through-hole packaging constraint during PCB layout planning.

Flip Flops Part Context

This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for high speed and moderate power consumption. The 74AS821A variant specifically addresses applications needing wide data path storage with tri-state control, serving as a critical interface element between processors and memory subsystems in legacy or specialized industrial electronics.
