74LVC163PW,118

Counter Dividers Overview

The Nexperia 74LVC163PW,118 is a synchronous presettable 4-bit binary counter housed in a TSSOP16 (SOT403-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports input voltages up to 5.5 V. The device features synchronous reset and parallel loading triggered by the positive-going edge of the clock signal. It includes an internal look-ahead carry mechanism to facilitate high-speed serial cascading via two count enable inputs (CEP and CET). The component complies with JEDEC standards for various voltage ranges and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Counter Dividers Feature Summary

• Synchronous operation with simultaneous flip-flop clocking on the positive-going edge.
• Internal look-ahead carry simplifies serial cascading of multiple counters.
• Inputs accept voltages up to 5.5 V for direct interface with TTL levels.
• CMOS technology ensures low power consumption across the operating range.

Counter Dividers Applications

• High-speed counting applications requiring precise timing control.
• Digital systems utilizing serial cascading for extended bit-counting capabilities.
• Circuits requiring synchronous data loading and reset functionality.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with parallel load capability is required. Ensure the design accommodates the 1.2 V to 3.6 V supply range and utilizes the positive-edge-triggered clock. The TSSOP16 package is suitable for surface-mount assembly where space efficiency is prioritized over the SO16 variant.

Counter Dividers Part Context

This part belongs to the 74LVC logic family, characterized by CMOS low power dissipation and compatibility with 3.3 V and 5 V systems. The 74LVC163 specifically addresses the need for synchronous control in binary counting sequences, distinguishing itself from asynchronous counterparts by eliminating ripple delay issues during state transitions.

Counter Dividers Replacement Considerations

The 74LVC163D serves as a pin-compatible alternative in the SO16 package. The 74LVC163BQ is available in the DHVQFN16 leadless package. Verify that any substitute maintains the same synchronous reset and parallel load functionality.
