54ACT163WRQMLV

Overview

The 54ACT163WRQMLV is a high-speed synchronous modulo-16 binary counter manufactured by National Semiconductor. It features a 4-bit positive-edge triggered architecture housed in a 16-CFP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports synchronous presettable functionality, enabling applications in programmable dividers.

Feature Summary

• High-speed synchronous modulo-16 binary counting capability
• Synchronous presettable design for programmable divider applications
• Positive edge triggering mechanism

Applications

• Programmable frequency dividers
• Digital counting systems
• Timing control circuits

Procurement Notes

Verify the specific WRQMLV suffix against official National Semiconductor documentation to confirm radiation hardening or military qualification status. Ensure the 16-CFP package type matches system requirements. Cross-reference datasheet revisions to validate electrical characteristics and pinout compatibility before integration.

Selection Notes

Select this component when a synchronous 4-bit binary counter with preset capability is required. The ACT logic family offers higher speed than standard LS counterparts. Verify that the 4.5 V to 5.5 V operating range aligns with the system power supply. Confirm package availability in 16-CFP format for physical integration.

Part Context

This part belongs to the '54ACT' series of high-speed CMOS logic devices produced by National Semiconductor. The series includes various flip-flops, buffers, and counters designed for digital logic applications requiring fast switching speeds and wide operating voltage ranges compatible with standard TTL levels.

Replacement Considerations

Compatible substitutes include other 54ACT163 variants from National Semiconductor or Texas Instruments, such as the 54ACT163DMQB, provided they share the same functional specifications and package constraints.
