74HCT163PW,118

Counter Dividers Overview

The Nexperia 74HCT163PW,118 is a synchronous presettable 4-bit binary counter housed in a 16-TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features synchronous counting, parallel loading, and synchronous reset capabilities. It includes two count enable inputs (CEP and CET) for cascading and an internal look-ahead carry output (TC). Input levels comply with TTL standards.

Counter Dividers Feature Summary

• Synchronous operation with simultaneous flip-flop clocking on the positive-going edge
• Internal look-ahead carry simplifies serial cascading of counters
• Inputs include clamp diodes for interfacing voltages exceeding VCC

Counter Dividers Applications

• Modulo counters requiring minimal external logic
• Digital timing sequences
• Frequency division circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP-16 package variant. Confirm that the HCT logic family input levels match the system's voltage requirements. Ensure the operating temperature range meets the application's environmental specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when TTL-compatible input levels are required for a synchronous 4-bit counter. The HCT series ensures compatibility with standard TTL logic outputs. Consider the 16-TSSOP package if surface-mount space constraints require a thin shrink outline form factor.

Counter Dividers Part Context

This part belongs to the 74HC/HCT163 family of synchronous presettable binary counters. It shares functional characteristics with the 74HC163 but utilizes HCT input thresholds compatible with Transistor-Transistor Logic (TTL) systems. The PW suffix indicates the plastic thin shrink small outline package.

Counter Dividers Replacement Considerations

Direct pin-to-pin replacements include other manufacturers' 74HCT163 variants in TSSOP-16 packages. Verify that any substitute maintains the same synchronous reset and parallel load functionality.
