M74HC393RM13TR

Counter Dividers Overview

The M74HC393RM13TR is a high-speed CMOS dual binary counter from STMicroelectronics, housed in a 14-pin SOIC package. It contains two independent 4-bit ripple carry counters with asynchronous master reset inputs. The device operates within a supply voltage range of 2V to 6V and features symmetrical output impedance with a minimum drive capability of 4mA. Maximum clock frequency reaches 79MHz at 6V, while quiescent current remains low at 4μA maximum.

Counter Dividers Feature Summary

• Dual independent 4-bit ripple carry binary counters
• Asynchronous master reset for count truncation
• Negative edge-triggered clock input
• High noise immunity with static discharge protection

Counter Dividers Applications

• Digital frequency division circuits
• Time base generation systems
• Pulse counting applications
• Divide-by-N counter configurations

Counter Dividers Procurement Notes

Verify the specific suffix RM13TR against official datasheets to confirm the surface-mount SO-14 packaging and tape-and-reel delivery format. Ensure compatibility with standard 74HC logic families regarding voltage levels and pinout assignments before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when requiring two separate 4-bit counters on a single chip. Verify that the negative edge-triggered operation aligns with system timing requirements. Confirm that the SO-14 package dimensions fit the available PCB footprint and that the operating temperature range meets environmental constraints.

Counter Dividers Part Context

This part belongs to the M74HC393 series of dual binary counters manufactured by STMicroelectronics. It utilizes silicon gate C2MOS technology for high-speed performance and low power dissipation. The device is functionally compatible with industry-standard 74LS393 counterparts but offers improved speed and lower power consumption characteristics.

Counter Dividers Replacement Considerations

Direct substitutes include other manufacturers' 74HC393 variants such as SN74HC393 or MC74HC393. Verify pin compatibility and electrical parameters before substitution.
