MC74HC160ADTR2G

Counter Dividers Overview

The MC74HC160ADTR2G is a high-performance silicon-gate CMOS presettable BCD counter manufactured by onsemi. It features a 4-bit synchronous count architecture with an asynchronous reset input and parallel load capability. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. It utilizes a TSSOP-16 surface-mount package and includes dedicated enable pins for count control and a ripple carry output for cascading applications.

Counter Dividers Feature Summary

• Features an asynchronous reset function that immediately clears internal flip-flops regardless of clock state.
• Provides synchronous parallel loading of preset data inputs onto outputs upon the rising edge of the clock signal.
• Includes dual count-enable controls (Enable P and Enable T) to manage counting operations and inhibit functions.
• Generates a ripple carry output pulse when the counter reaches its maximum state, facilitating multi-stage expansion.

Counter Dividers Applications

• N-bit synchronous counters via cascaded configurations
• Nibble ripple counters using ripple carry output connections
• Programmable BCD counting sequences with external preset data

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DT' confirms the TSSOP-16 package type required for your PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the specified industrial temperature range requirements for your target environment.

Counter Dividers Selection Notes

Select this component for designs requiring a standard 4-bit BCD counter with synchronous operation and asynchronous reset capabilities. It serves as a pin-compatible alternative to LS160 devices while offering CMOS compatibility with standard logic families. Consider the propagation delay specifications relative to your system clock frequency constraints.

Counter Dividers Part Context

This part belongs to the MC74HC160A series of programmable BCD counters produced by onsemi. It is part of the broader High-Speed CMOS (HC) logic family, designed for high-speed digital applications. The device shares identical pinouts with legacy LS160 counterparts, allowing for direct replacement in existing designs.

Counter Dividers Replacement Considerations

The datasheet indicates the HC160A is identical in pinout to the LS160. Verify electrical characteristics such as drive capability and speed against original design requirements when substituting.
