74ACT163MTC

Counter Dividers Overview

The onsemi 74ACT163MTC 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 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features synchronous presettable loading, two Count Enable inputs, and a Terminal Count output for multistage expansion. Typical count rates reach 125 MHz with outputs capable of sourcing or sinking 24 mA.

Counter Dividers Feature Summary

• Synchronous counting and parallel loading controlled by dedicated enable inputs
• Outputs provide high drive capability with 24 mA source/sink current
• Inputs are TTL-compatible for direct interfacing with standard logic families

Counter Dividers Applications

• Programmable frequency dividers
• Synchronous multistage counters
• Digital timing circuits

Counter Dividers Procurement Notes

Verify the specific ordering code against manufacturer documentation to confirm package type and suffix variations. Ensure design compliance with absolute maximum ratings regarding supply voltage and input currents. Confirm RoHS status and lifecycle stage prior to finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when synchronous operation and high-speed performance are required. The ACT series offers TTL-compatible inputs suitable for mixed-voltage systems. Verify that the TSSOP package dimensions fit the target PCB layout constraints and thermal requirements.

Counter Dividers Part Context

This part belongs to the 74AC/ACT163 family of synchronous presettable binary counters. It shares functional characteristics with other members like the MC74ACT163DG but differs in physical packaging. The MTC suffix specifically denotes the 16-lead TSSOP form factor.

Counter Dividers Replacement Considerations

Check datasheets for alternative manufacturers offering identical pinouts and electrical specifications. Verify compatibility with existing board layouts and signal integrity requirements before substitution.
