SN74LV163ARGYR

Counter Dividers Overview

The SN74LV163ARGYR is a 4-bit synchronous binary counter from Texas Instruments, operating within a 2V to 5.5V supply voltage range. It features internal look-ahead carry circuitry for high-speed counting and supports mixed-mode voltage operation across all ports. The device utilizes a 16-pin VQFN package (RGY) with dimensions of 4mm x 3.5mm. Key electrical characteristics include a maximum propagation delay of 9.5ns at 5V and typical output ground bounce of 2.3V at 3.3V. It operates reliably between -40°C and +85°C.

Counter Dividers Feature Summary

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

Counter Dividers Applications

• High-speed synchronous binary counting applications
• Cascaded multi-bit counter designs utilizing ripple-carry output
• Mixed-mode voltage systems requiring compatible port operations
• Partial-power-down environments necessitating output isolation

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'RGYR' corresponds to the active production status and 3000-unit large tape-and-reel carrier configuration. Confirm RoHS compliance and lead finish specifications match project requirements. Ensure thermal management aligns with the junction-to-ambient resistance metrics provided in the datasheet for the VQFN package.

Counter Dividers Selection Notes

Select this component when a compact surface-mount solution is required for 4-bit synchronous binary counting. The VQFN package offers a smaller footprint compared to SOIC or TSSOP alternatives. Consider the internal look-ahead feature if system timing constraints demand minimal propagation delay during cascade operations.

Counter Dividers Part Context

This part belongs to the SN74LV163A family of 4-bit synchronous binary counters manufactured by Texas Instruments. The family includes various package options such as SOIC, SSOP, TVSOP, SOP, and TSSOP. The RGY variant specifically denotes the VQFN package type, providing distinct mechanical dimensions suitable for space-constrained printed circuit board layouts.

Counter Dividers FAQ

How does the SN74LV163ARGYR handle parallel loading?

Parallel loading is performed synchronously. A low level at the LOAD input disables the counter, causing the outputs to update with the preset data on the next rising edge of the clock pulse.

What is the function of the RCO pin?

The Ripple-Carry Output (RCO) generates a high-level pulse when the count reaches its maximum value and ENT is high. This signal enables successive cascaded stages for n-bit applications.
