SN74LV163ADR

Counter Dividers Overview

The SN74LV163ADR is a 4-bit synchronous binary counter from the Texas Instruments LV-A logic series. It operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode voltage operation on 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 utilizes a rising-edge triggered clock input and provides synchronous parallel load, clear, and count functions. The component is housed in a 16-pin SOIC package.

Counter Dividers Feature Summary

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

Counter Dividers Applications

• High-speed synchronous counting designs
• n-bit cascaded counter applications
• Partial-power-down system implementations

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SN74LV163ADR designation aligns with the intended 16-pin SOIC physical dimensions and pinout configuration before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when designing systems requiring synchronous binary counting with minimal propagation delay. Ensure the operating environment falls within the -40°C to +85°C temperature range and that the supply voltage remains between 2 V and 5.5 V. Verify compatibility with existing logic levels if mixed-voltage operation is utilized.

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 Low-Voltage CMOS technology optimized for 2V to 5.5V operation. The 'ADR' suffix specifically identifies the SOIC-16 surface-mount package variant supplied in a reel format.
