SN74LS162AN

Counter Dividers Overview

The SN74LS162AN is a synchronous decade counter from the 74LS series, manufactured by Texas Instruments. It features four-bit BCD counting with synchronous preset and synchronous clear capabilities. The device operates on a positive edge-triggered clock and includes two count enable inputs for cascading. It supports a typical count rate of 35 MHz and functions within a supply voltage range of 4.75 V to 5.25 V.

Counter Dividers Feature Summary

• Synchronous parallel loading allows data input to be set on the rising clock edge.
• Synchronous clear function resets the counter state only during active clock transitions.
• Dual count enable inputs facilitate high-speed synchronous expansion and cascading.

Counter Dividers Applications

• Frequency division circuits
• Memory addressing systems
• Digital counting applications

Counter Dividers Procurement Notes

Verify the manufacturer designation carefully, as the SN prefix typically indicates Texas Instruments while the brand specified is onsemi. Confirm that the specific part number matches the intended datasheet specifications regarding package type and electrical characteristics before procurement.

Counter Dividers Selection Notes

Select this component when synchronous control of reset and load operations is required to avoid glitches associated with asynchronous methods. Ensure the design utilizes a positive edge-triggered clock source compatible with LS logic levels and standard TTL voltage requirements.

Counter Dividers Part Context

This integrated circuit belongs to the 74LS family of low-power Schottky logic devices. It serves as a building block for sequential logic designs, specifically functioning as a modulo-10 counter. It is distinct from binary counters like the 74LS161 which operate modulo-16.
