74ACT163MTR

Counter Dividers Overview

The STMicroelectronics 74ACT163MTR is a synchronous presettable 4-bit binary counter fabricated with advanced high-speed CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and features a typical maximum clock frequency (fMAX) of 250MHz at VCC = 5V. The device includes four fundamental modes: synchronous reset, parallel load, count-up, and hold. It provides symmetrical output impedance with |IOH| = IOL = 24mA minimum drive capability and balanced propagation delays. Key electrical specifications include a maximum quiescent supply current (ICC) of 8μA and TTL-compatible input/output levels.

Counter Dividers Feature Summary

Counter Dividers Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that available substitutes meet all required electrical parameters, specifically operating voltage ranges and pin compatibility. Ensure design modifications accommodate any differences in package dimensions or thermal characteristics when transitioning from the discontinued 74ACT163MTR to alternative sources.

Counter Dividers Selection Notes

Select this component for applications demanding high-speed synchronous counting with low power consumption. It is suitable for designs requiring direct interface with TTL logic families due to its compatible voltage thresholds. Consider the 24mA output drive capability for driving moderate capacitive loads. Evaluate the need for synchronous clear and parallel load functions versus asynchronous alternatives when defining system timing requirements.

Counter Dividers Part Context

This part belongs to the 74ACT series of advanced high-speed CMOS logic devices manufactured by STMicroelectronics. The 74ACT family offers performance comparable to the older 74LS series but with significantly faster switching speeds and lower power consumption. The 'M' suffix indicates the SO-16 surface mount package, while 'TR' denotes tape and reel packaging for automated assembly processes.
