Latches Procurement Notes

Verify the specific suffix M96 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 20-SOIC footprint matches the target PCB design constraints. Ensure the AC logic family compatibility aligns with existing system voltage levels and signal integrity requirements before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring high-density octal latching with three-state output control. The AC logic family offers superior speed compared to standard 74LS counterparts while maintaining lower power dissipation than older HC families. Consider the wide voltage tolerance for mixed-signal environments where supply rails may vary between 1.5 V and 5.5 V during operation.

Latches Part Context

This part belongs to the Texas Instruments CD74AC series of advanced CMOS logic devices. The 74AC family is designed for high-speed digital applications requiring low power consumption. The octal latch configuration allows simultaneous storage of eight bits of data, making it suitable for parallel data handling tasks in complex digital systems.

Latches FAQ

What is the maximum propagation delay at 1.5 V supply?

The maximum propagation delay is 106 ns when operating at a 1.5 V supply voltage.

Does the device support bidirectional data flow?

No, the CD74AC373 is a unidirectional transparent latch; data flows only from inputs to outputs upon clock enablement.
