74AC191MTC

Counter Dividers Overview

The Fairchild Semiconductor 74AC191MTC is a high-speed binary counter integrated circuit housed in a 16-TSSOP surface-mount package. It operates as a synchronous, positive edge-triggered device with bidirectional counting capabilities. The component supports a supply voltage range of 2V to 6V and functions within an operating temperature range of -40°C to 85°C. It contains one element with four bits per element, designed for efficient data storage and sequential logic applications.

Counter Dividers Feature Summary

• Synchronous operation triggered by the positive edge of the clock signal
• Bidirectional counting capability allowing both up and down sequences
• High-speed performance suitable for demanding digital timing requirements

Counter Dividers Applications

• Binary counting circuits requiring precise synchronization
• Sequential logic systems utilizing up/down count modes
• Digital timing and frequency division applications

Counter Dividers Procurement Notes

Verify the manufacturer part number against official datasheets to ensure authenticity. Confirm that the 16-TSSOP package matches design specifications. Check for RoHS compliance status if environmental regulations apply. Ensure the supply voltage and temperature ranges align with system constraints before integration.

Counter Dividers Selection Notes

Select this component when a synchronous, bidirectional binary counter is required in a compact surface-mount form factor. The 74AC series offers higher speed compared to standard HC variants. Verify that the 2V to 6V supply range fits the target power architecture. Consider the 16-pin TSSOP footprint for PCB layout compatibility.

Counter Dividers Part Context

This device belongs to the 74AC logic family, known for advanced CMOS technology offering high speed and low power consumption. The 74AC191 specifically implements a 4-bit synchronous counter function. It is distinct from asynchronous counters or other bit-width configurations within the same logical family.

Counter Dividers Replacement Considerations

Check for equivalent parts such as the 74AC191SCT which shares similar functional characteristics. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the synchronous bidirectional counting feature.
