SN74LV163APW

Counter Dividers Overview

The SN74LV163APW is a 4-bit synchronous binary counter from the Texas Instruments SN74LV163A series. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode voltage operation on all ports. The device features internal look-ahead circuitry for fast counting and provides a ripple-carry output (RCO) for n-bit cascading. It includes synchronous parallel load, synchronous clear, and Ioff support for partial-power-down mode. The component is housed in a 16-pin TSSOP package.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with simultaneous flip-flop clocking
• Internal carry look-ahead for high-speed cascading applications
• Supports mixed-mode voltage operation across all ports
• Ioff circuitry prevents damaging current backflow during partial-power-down

Counter Dividers Applications

• High-speed synchronous counting designs
• N-bit cascaded counter systems
• Partial-power-down applications requiring output isolation

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum. Confirm RoHS compliance status and lead finish details as these vary by production batch. Ensure the selected variant matches the required moisture sensitivity level and peak reflow temperature specifications for your assembly process.

Counter Dividers Selection Notes

Select this component when a 4-bit synchronous binary counter with low-voltage compatibility is required. The LV163A series is suitable for designs needing mixed-mode voltage interfaces. Verify that the TSSOP-16 package dimensions fit the target PCB layout constraints. Consider the internal carry look-ahead feature if multiple counters must be cascaded without external gating logic.

Counter Dividers Part Context

This part belongs to the SN74LV163A family of 4-bit synchronous binary counters. The 'PW' suffix specifically denotes the 16-pin Thin-Shrink Small-Outline Package (TSSOP). While other variants like SN74LV163ADR exist in different packages such as SOIC or VQFN, the APW variant is distinct due to its physical form factor and historical production status.

Counter Dividers Replacement Considerations

SN74LV163APWR is an active production replacement for the obsolete SN74LV163APW. Both share the same TSSOP-16 package and electrical characteristics. Verify that the active replacement meets all thermal and mechanical requirements for the existing design.
