MM74HC393MTC

Counter Dividers Overview

The MM74HC393MTC is a dual 4-bit binary counter manufactured by onsemi, housed in a 14-lead Thin Shrink Small Outline Package (TSSOP). It utilizes advanced silicon-gate CMOS technology and features two independent ripple carry counters. Each counter increments on the negative edge of the clock input and includes an independent active-high clear input for count truncation or divide-by-N configurations. The device supports a supply voltage range of 2V to 6V and operates within a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Contains two independent 4-bit ripple carry binary counters capable of cascading to form a single divide-by-256 counter.
• Features asynchronous clearing of all four bits per counter via an independent active-high clear input.
• Inputs are protected against static discharge damage through internal diodes connected to VCC and ground.

Counter Dividers Applications

• Count truncation applications requiring specific modulus values.
• Implementation of divide-by-N counter configurations.
• Cascaded systems requiring a single divide-by-256 counter function.

Counter Dividers Procurement Notes

Verify the package designation MTC14 corresponds to the 14-lead TSSOP format with a 4.4mm width. Confirm the logic family is HC series compatible with TTL loads. Ensure environmental compliance matches project requirements. Check for specific ordering suffixes if tape and reel packaging is required instead of tube.

Counter Dividers Selection Notes

Select this component when a dual 4-bit binary counter is needed in a surface-mount TSSOP package. It serves as a functional equivalent to the 74LS393 while offering lower power consumption due to CMOS technology. Consider the operating frequency limits and propagation delays relative to the system clock speed and load capacitance requirements.

Counter Dividers Part Context

This part belongs to the MM74HC393 series of dual 4-bit binary counters. It is functionally and pin-compatible with the 74LS393 standard logic counterpart. The device is available in multiple packages including SOIC, SOP, PDIP, and TSSOP, allowing flexibility in PCB layout and thermal management strategies for various electronic designs.

Counter Dividers Replacement Considerations

The datasheet states the device is functionally and pin equivalent to the 74LS393. Other variants in the MM74HC393 series are available in different packages such as SOIC (M14A) or PDIP (N14A).
