SN74LV163APWR

Counter Dividers Overview

The SN74LV163APWR is a 4-bit synchronous binary counter from Texas Instruments, designed for VCC operation between 2V and 5.5V. It features internal look-ahead carry circuitry to support high-speed counting applications without additional gating. The device operates on the rising edge of the clock signal and includes synchronous parallel load and clear functions. It supports mixed-mode voltage operation across all ports and incorporates Ioff circuitry to facilitate partial-power-down mode by preventing damaging backflow currents.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with simultaneous flip-flop triggering
• Internal carry look-ahead circuitry for efficient n-bit cascading
• Supports mixed-mode voltage operation on all input and output ports
• Ioff circuitry enables safe partial-power-down mode operation

Counter Dividers Applications

• High-speed synchronous counting designs
• Multi-stage n-bit counter cascading systems
• Mixed-mode voltage logic interface circuits
• Partial-power-down compatible digital systems

Counter Dividers Procurement Notes

Verify the specific package type and ordering suffix against the manufacturer's current Package Option Addendum. Confirm RoHS compliance status and lead finish details directly from the official documentation before procurement. Ensure the selected variant matches the required moisture sensitivity level and operating temperature range specifications.

Counter Dividers Selection Notes

Select this component when a 4-bit synchronous binary counter is required within a 2V to 5.5V supply range. The internal carry look-ahead feature makes it suitable for high-frequency applications where ripple-carry delays are unacceptable. Verify that the TSSOP-16 package dimensions align with the target PCB layout constraints.

Counter Dividers Part Context

This device belongs to the SN74LV163A family of 4-bit synchronous binary counters manufactured by Texas Instruments. The 'PW' suffix indicates the part is housed in a TSSOP (Thin Shrink Small-Outline Package) with 16 pins. This family is characterized by low-voltage CMOS technology optimized for performance across varying supply voltages.
