SN74LV163ADGVR

Counter Dividers Overview

The SN74LV163ADGVR is a 4-bit synchronous binary counter from the Texas Instruments LV series. It operates within a supply voltage range of 2V to 5.5V and features internal carry look-ahead for high-speed counting applications. The device supports synchronous parallel loading, synchronous clearing, and cascading via a ripple-carry output (RCO). It utilizes a TVSOP-16 package and includes Ioff circuitry to support partial-power-down modes.

Counter Dividers Feature Summary

• Supports mixed-mode voltage operation across all ports
• Features internal carry look-ahead for fast counting
• Includes Ioff circuitry for partial-power-down mode operation

Counter Dividers Applications

• High-speed synchronous counting designs
• Cascaded n-bit counter systems
• Presettable binary counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-16 package type. Confirm RoHS compliance status and lead finish details against the latest Package Option Addendum. Ensure the component matches the active production or NRND status indicated in current TI documentation before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a 4-bit synchronous binary counter with internal carry look-ahead is required. It is suitable for designs needing synchronous preset and clear functions. Verify that the operating voltage falls between 2V and 5.5V and that the TVSOP-16 package fits the board layout constraints.

Counter Dividers Part Context

This part belongs to the SN74LV163A family of 4-bit synchronous binary counters. The 'LV' designation indicates Low-Voltage CMOS technology. The 'DGVR' suffix specifies the TVSOP-16 package and reel packaging format. It is distinct from asynchronous counters like the 74LS163.

Counter Dividers FAQ

Is the clear function asynchronous?

No, the clear function for the SN74LV163A devices is synchronous.

What is the purpose of the RCO pin?

The RCO (Ripple-Carry Output) enables cascading counters for n-bit synchronous applications without additional gating.
