SN74HC163ANS

Counter Dividers Overview

The SN74HC163ANS is a synchronous 4-bit binary counter from the Texas Instruments 74HC logic family. It features an up-counting sequence with synchronous parallel data loading and synchronous reset capabilities. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 36 MHz. It is housed in a 16-pin SOIC surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with up-counting direction
• Parallel data input for synchronous preset loading
• Synchronous clear function controlled by dedicated input
• High-speed operation supporting up to 36 MHz clock rates

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division and counting applications
• Event counting systems
• Control logic requiring precise state tracking

Counter Dividers Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official documentation to confirm the package type, lead material, and environmental compliance status. Ensure the ordering part number matches the required tape-and-reel or cut-tape configuration for your assembly process. Cross-reference the datasheet revision date to confirm current electrical specifications and pinout definitions before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with parallel load capability is required in a surface-mount design. The HC series offers standard CMOS performance suitable for general-purpose digital logic. Consider the 36 MHz maximum operating speed and 2 V to 6 V supply range compatibility with your system's power rails and signal integrity requirements.

Counter Dividers Part Context

This component belongs to the SN74HC163 series of synchronous 4-bit binary counters manufactured by Texas Instruments. It is part of the broader 74HC logic family, which provides high-speed CMOS performance compatible with standard TTL inputs. The 'A' typically denotes a specific package variant, while 'N' often indicates a non-JEDEC compliant or specific lead finish option depending on the manufacturer's coding scheme.

Counter Dividers Replacement Considerations

Direct functional equivalents include the SN74HC163DR (SOIC-16) and SN74HC163DRE4. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength before substitution. Alternative packages like DIP or TSSOP variants may require adapter solutions if footprint constraints differ.
