SN74ABT821ANT

Flip Flops Overview

The SN74ABT821ANT is a 9-bit bus-interface flip-flop from the Texas Instruments ABT logic series, housed in a 24-pin PDIP package. It features non-inverting D-type edge-triggered operation with three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 13 ns at 5 V with 50 pF load. Output drive capabilities include -24 mA high-level and 48 mA low-level currents. It functions across an operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Provides 9-bit parallel data storage via D-type edge-triggered architecture
• Features three-state outputs for efficient bus interfacing and system isolation
• Delivers high current drive capability suitable for direct bus loading

Flip Flops Applications

• Parallel data buffering in computer systems
• Bus interface circuits requiring temporary data storage
• High-speed digital signal routing applications

Flip Flops Procurement Notes

Verify the specific suffix 'ANT' corresponds to the PDIP-24 through-hole package variant when sourcing. Confirm that the required operating temperature range aligns with the commercial grade specification (0°C to 70°C) rather than industrial or extended ranges. Ensure compatibility with 5V logic levels and check for availability as this component may be subject to lifecycle changes.

Flip Flops Selection Notes

Select this component when a 9-bit wide bus interface is required with moderate speed requirements. The ABT series offers a balance between speed and power consumption compared to older LS or AS families. Consider the PDIP package only if through-hole assembly is mandated by the PCB design constraints. Verify that the 5V-only supply requirement fits the system power architecture.

Flip Flops Part Context

This part belongs to the SN74ABT family of advanced bipolar technology logic devices. These components are designed for high-speed applications requiring fast switching times while maintaining lower power dissipation than standard Schottky TTL. The 821A variant specifically addresses multi-bit data path management in legacy and modern mixed-signal systems.
