74ACT163SJX

Counter Dividers Overview

The onsemi 74ACT163SJX is a high-speed synchronous modulo-16 binary counter housed in a 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide. It features TTL-compatible inputs and outputs capable of sourcing or sinking 24 mA. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a typical count rate of 125 MHz. Key electrical characteristics include propagation delays from clock to output ranging from 1.5 ns to 12.0 ns depending on load conditions.

Counter Dividers Feature Summary

• Synchronous presettable design with parallel data loading capabilities
• TTL-compatible input thresholds for direct interfacing
• High-speed synchronous expansion via Terminal Count output
• Robust output drive strength supporting significant capacitive loads

Counter Dividers Applications

• Programmable frequency dividers
• Synchronous multistage counter systems
• Digital timing and sequencing circuits
• Event counting applications

Counter Dividers Procurement Notes

Verify the specific SOP package width and lead form against mechanical constraints. Confirm that the 4.5V to 5.5V operating range aligns with the system power supply. Ensure input signal levels meet the specified TTL-compatible thresholds for reliable logic state recognition during operation.

Counter Dividers Selection Notes

Select this component when synchronous reset and parallel load functionality are required within a modulo-16 counting sequence. Consider the 125 MHz typical count rate for high-frequency timing applications. Verify that the 16-pin SOP footprint fits the available PCB real estate compared to SOIC or TSSOP alternatives.

Counter Dividers Part Context

This part belongs to the 74ACT163 series of synchronous binary counters. It shares functional similarities with the 74AC163 but includes ACT-specific TTL-compatible input characteristics. The 'SJ' suffix denotes the specific 16-lead SOP physical package, while the 'X' suffix typically indicates tape and reel packaging availability.

Counter Dividers Replacement Considerations

The 74ACT163SCX serves as a pin-compatible alternative utilizing a SOIC-14 package variant. The MC74ACT163DW offers a similar logical function in a SOIC-16 package. Verify package dimensions and pinout compatibility before substituting.
