74LVC163PW,112

Counter Dividers Overview

The Nexperia 74LVC163PW,112 is a synchronous presettable 4-bit binary counter housed in a TSSOP16 (SOT403-1) package. It operates on a wide supply voltage range from 1.2 V to 3.6 V with inputs accepting voltages up to 5.5 V. The device features synchronous reset and parallel loading triggered by the positive-going edge of the clock input. It includes an internal look-ahead carry mechanism to simplify serial cascading through two count enable inputs (CEP and CET) and a terminal count output (TC). The component complies with JEDEC standards for various voltage ranges and supports operating temperatures from -40 °C to +125 °C.

Counter Dividers Feature Summary

• Synchronous operation with simultaneous flip-flop clocking on the positive-going edge
• Internal look-ahead carry circuitry simplifies serial cascading of counters
• Inputs accept voltages up to 5.5 V while operating at lower supply voltages
• Synchronous master reset allows modification of maximum count with minimal external logic

Counter Dividers Applications

• High-speed counting applications requiring precise timing control
• Digital systems utilizing serial cascaded counter configurations
• Mixed-voltage environments interfacing 5 V logic with lower voltage subsystems

Counter Dividers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP16 plastic thin shrink small outline package variant. Confirm that the required temperature range covers -40 °C to +125 °C for your application environment. Ensure design compatibility with the synchronous reset and parallel load functionality described in the functional table. Check for any recent product data sheet revisions that may affect pinning or electrical characteristics.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with parallel load capability is required. The LVC family is suitable for designs needing direct interface with TTL levels and low power consumption. Consider the TSSOP16 package if space constraints allow for its body width of 4.4 mm. Verify that the maximum clock frequency requirements align with the propagation delay specifications across the intended supply voltage range.

Counter Dividers Part Context

This part belongs to the 74LVC series of advanced very-low-voltage CMOS logic devices manufactured by Nexperia. The 74LVC163 specifically provides synchronous presettable 4-bit binary counting functionality. It is distinct from asynchronous counters and other bit-width variants within the same logic family. The PW suffix denotes the specific TSSOP16 packaging option available for this model.
