SNJ54AS823AJT

Flip Flops Overview

The SNJ54AS823AJT is a military-grade, 9-bit bus interface flip-flop manufactured by Texas Instruments. It features three-state outputs designed for driving highly capacitive or low-impedance loads. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum propagation delay of 13ns at 5V with 50pF load capacitance. Output drive capabilities include 24mA high and 48mA low currents. It utilizes a 24-pin ceramic dual in-line package (CDIP) and functions as a positive-edge-triggered D-type flip-flop with master reset functionality.

Flip Flops Procurement Notes

Verify the specific suffix 'JT' indicates the ceramic dual in-line package (CDIP) construction required for military specifications. Confirm that the component meets the necessary environmental standards for -55°C to 125°C operation. Ensure compatibility with existing board layouts for the 24-pin CDIP form factor. Check for any specific quality assurance documentation required for defense or aerospace procurement channels.

Flip Flops Selection Notes

Select this component when military-grade performance and wide temperature tolerance are mandatory. It is suitable for designs requiring robust drive strength for heavy capacitive loads. Consider the ceramic package for superior thermal and mechanical stability compared to plastic variants. Evaluate the 9-bit width against system data path requirements to ensure optimal pin utilization.

Flip Flops Part Context

This part belongs to the Texas Instruments 54AS series, which provides advanced Schottky logic performance for military applications. It serves as a 9-bit variant within the AS823 family of bus interface flip-flops. The device complements other 54AS components like the SNJ54AS240AJ buffer, offering synchronized data storage with high-speed tri-state output control for complex digital architectures.

Flip Flops Replacement Considerations

The SN74AS823ANT is a commercial-grade equivalent but lacks the military temperature range and ceramic packaging. For direct replacements, verify if the SN54AS823A datasheet lists compatible cross-reference numbers. Ensure any substitute maintains the 24-pin CDIP footprint and 54-series electrical characteristics.
