74AC163MTC

Counter Dividers Overview

The onsemi 74AC163MTC is a high-speed synchronous modulo-16 binary counter housed in a 16-Lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device features synchronous counting, parallel loading, and a synchronous reset input that overrides other functions. It includes two Count Enable inputs (CEP and CET) and a Terminal Count output for multistage expansion. Outputs can source or sink up to 24 mA.

Counter Dividers Feature Summary

• Synchronous counting and loading with positive edge-triggered operation
• Synchronous reset input that overrides counting and parallel loading
• High-speed synchronous expansion capability via Terminal Count output
• Outputs capable of sourcing and sinking 24 mA

Counter Dividers Applications

• Programmable frequency dividers
• Synchronous multistage counters
• Digital timing circuits requiring precise state sequencing

Counter Dividers Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and tape/reel availability. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Confirm that the TSSOP-16 footprint matches the design layout specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a synchronous modulo-16 binary counter is required with high-speed performance and flexible expansion options. The AC series offers a wide supply voltage range suitable for various logic families. Consider the ACT variant if TTL-compatible input thresholds are necessary for interfacing with legacy systems.

Counter Dividers Part Context

This part belongs to the 74AC logic family, characterized by high speed and low power consumption compared to standard CMOS. It is functionally compatible with the 74HC and 74HCT families but offers superior switching speeds. The MTC suffix specifically denotes the 16-lead TSSOP package format.

Counter Dividers Replacement Considerations

The 74ACT163MTC serves as a direct functional replacement with TTL-compatible inputs. Other manufacturers' equivalents in the 74AC163 family may be considered if pinout and electrical characteristics align with the original design requirements.
