CD74HC193M

Counter Dividers Overview

The CD74HC193M is a synchronous 4-bit up/down binary counter manufactured by Harris Corporation. It operates within a supply voltage range of 2V to 6V and supports a maximum frequency of 38MHz. The device features positive edge triggering for both count-up and count-down operations, with independent clock inputs. It is housed in a 16-SOIC surface-mount package and functions across an industrial temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit bidirectional counting capability
• Independent clock inputs for up and down operations
• Positive edge triggered logic
• CMOS construction for low power consumption

Counter Dividers Applications

• Digital frequency division circuits
• Timing sequence generation systems
• Pulse counting applications

Counter Dividers Procurement Notes

Verify the manufacturer origin as Harris Corporation or authorized successor entities like Texas Instruments/Rochester Electronics due to legacy status. Confirm RoHS compliance requirements, as original Harris versions may not meet current environmental standards. Ensure the SOIC-16 package dimensions match the target PCB footprint before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous bidirectional counter is required with CMOS compatibility. The HC series offers higher speed than standard 74LS counterparts. Verify that the operating voltage aligns with the 2V-6V range and that the 16-SOIC package fits the assembly constraints. Consider thermal management for operation near the upper temperature limit.

Counter Dividers Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It serves as a fundamental building block for digital timing and control systems. The 'M' suffix indicates the surface-mount SOIC package variant. It is distinct from asynchronous counters like the 74HC393.

Counter Dividers Replacement Considerations

CD74HC193MT (Texas Instruments) is a confirmed equivalent offering identical logical functionality and pinout compatibility.
