M38510/32502BSA

Latches Overview

The M38510/32502BSA is a military-grade octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight positive-edge-triggered D-type flip-flops with 3-state outputs, housed in a 20-lead Ceramic Flat Pack (CFP) package. The device operates within a temperature range of -55°C to 125°C and complies with MIL-PRF-38535 Class B specifications.

Latches Feature Summary

• Provides eight parallel data storage elements utilizing positive-edge-triggered D-type flip-flops for synchronous data capture.
• Integrates high-impedance 3-state outputs designed to drive highly capacitive or low-impedance loads directly on bus lines without interface components.
• Includes an output control input that independently places all outputs in a high-impedance state while retaining internal data integrity.

Latches Applications

• Implementation of buffer registers in digital systems
• Construction of bidirectional bus drivers
• Design of I/O ports for data interfacing
• Utilization as working registers in memory architectures

Latches Procurement Notes

Verify the component meets MIL-PRF-38535 Class B screening requirements. Confirm the specific suffix 'BSA' corresponds to the CFP package variant. Ensure compatibility with system voltage levels and thermal management needs for the specified operating temperature range.

Latches Selection Notes

Select this component when a robust, military-specification octal register with tri-state capability is required. It is suitable for applications demanding high noise immunity and direct bus driving. Compare against standard commercial variants if extended temperature ranges or lower costs are not critical factors.

Latches Part Context

This part belongs to the SN54LS374 family of octal D-type flip-flops. It shares functional characteristics with commercial counterparts like the SN74LS374 but adheres to stricter military reliability standards. The device is part of Texas Instruments' long-standing portfolio of logic circuits designed for high-reliability environments.

Latches FAQ

How does the output control input function?

The output control input places the eight outputs in either a normal logic state or a high-impedance state. This action does not affect the internal operation of the flip-flops, allowing data retention even when outputs are disabled.

What is the triggering mechanism for the data inputs?

The device uses positive-edge-triggered D-type flip-flops. Data at the D inputs is captured and transferred to the Q outputs on the positive transition of the clock signal.
