M74HC373RM13TR

Latches Overview

The M74HC373RM13TR is an octal D-type latch with 3-state outputs manufactured using sub-micron silicon gate C2MOS technology. It operates within a supply voltage range of 2V to 6V and features symmetrical output impedance with a minimum drive capability of 6mA. The device provides high noise immunity, where the high and low level input voltages are defined as 28% of VCC. Propagation delays from LE/D to Q are typically 12ns at 6V, with balanced tPLH and tPHL characteristics.

Latches Feature Summary

• Octal D-type latching functionality controlled by Latch Enable (LE) and Output Enable (OE) inputs
• Three-state output configuration allowing direct bus-organized system connections
• High speed performance combined with low power CMOS dissipation
• Input protection circuits against static discharge and transient excess voltage

Latches Applications

• Bus-organized system data storage
• Register applications requiring 3-state isolation
• Parallel-to-serial conversion interfaces

Latches Procurement Notes

Verify the specific package type for the RM13 suffix, which corresponds to SOP-20 in official documentation. Confirm that the required operating temperature range covers -55°C to 125°C for your application environment. Ensure compatibility with the 2V to 6V supply voltage limits before integration into the circuit design.

Latches Selection Notes

Select this component when an octal latch with tri-state control is required for bus systems. It is suitable for designs needing high noise immunity and wide voltage operation. Consider the 12ns typical propagation delay for timing constraints. Verify pinout compatibility if replacing legacy 74LS373 equivalents in existing layouts.
