SN74LV163ADBR

Counter Dividers Overview

The SN74LV163ADBR is a 4-bit synchronous binary counter from the Texas Instruments LV-A logic series, housed in a 16-pin SSOP package. It operates on a supply voltage of 2 V to 5.5 V and supports mixed-mode voltage operation across all ports. The device features internal look-ahead circuitry for high-speed counting and includes a ripple-carry output (RCO) for n-bit cascading. It provides synchronous parallel loading and clearing functions triggered by the rising edge of the clock input.

Counter Dividers Feature Summary

• Synchronous counting with simultaneous flip-flop triggering to eliminate output spikes
• Internal carry look-ahead circuitry enables fast cascading without additional gating
• Supports partial-power-down mode via Ioff circuitry to prevent backflow current
• Latch-up performance exceeds 100 mA per JESD 78, class II

Counter Dividers Applications

• High-speed synchronous binary counting applications
• Multi-stage n-bit counter designs utilizing ripple-carry output
• Mixed-mode voltage systems requiring compatible port operations
• Partial-power-down environments utilizing Ioff functionality

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DB' corresponds to the SSOP-16 package variant when sourcing. Confirm RoHS compliance status and lead finish details against the latest Package Option Addendum. Ensure design implementation accounts for the recommended operating temperature range and thermal resistance metrics provided in the datasheet specifications.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous presettable binary counting within the 2 V to 5.5 V supply range. The internal look-ahead feature makes it suitable for high-frequency applications where propagation delay must be minimized. Consider the SSOP-16 footprint constraints and verify that the required count enable inputs (ENP, ENT) align with the system control logic.

Counter Dividers Part Context

This part belongs to the SN74LV163A family of 4-bit synchronous binary counters manufactured by Texas Instruments. The 'LV' designation indicates compatibility with low-voltage CMOS standards while maintaining robust drive capabilities. The 'DB' suffix specifically identifies the surface-mount SSOP package configuration used in this orderable part number.

Counter Dividers Replacement Considerations

SN74LV163ADRG4 is an active production alternative in the same SOIC package family.
