MC74HC160ADR2G

Counter Dividers Overview

The MC74HC160ADR2G is a high-performance silicon-gate CMOS programmable BCD counter manufactured by onsemi. It features an asynchronous reset input, parallel load capability, and synchronous or asynchronous reset functionality. The device operates within a voltage range of 2.0 V to 6.0 V and includes count-enable controls (Enable P and Enable T) along with a ripple carry output for cascading applications. Packaged in a SOIC-16 surface-mount format, it provides direct interface compatibility with CMOS, NMOS, and TTL logic families.

Counter Dividers Feature Summary

• Features an asynchronous reset mechanism that forces internal flip-flops and outputs to a low level upon activation.
• Includes dedicated count-enable pins (Enable P and Enable T) to control counting operations and manage the ripple carry output state.
• Provides a ripple carry output pin that signals when the counter reaches its maximum BCD state, facilitating external look-ahead carry pulses.

Counter Dividers Applications

• N-bit synchronous counters via cascaded configurations
• Nibble ripple counters
• Programmable BCD counting sequences

Counter Dividers Procurement Notes

Verify the specific package suffix 'ADR2G' corresponds to the SOIC-16 tape and reel shipping configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure the procurement documentation matches the exact part number to avoid functional discrepancies with similar logic families.

Counter Dividers Selection Notes

Select this component for designs requiring a 4-bit BCD counter with asynchronous reset capabilities. It is suitable for systems needing direct interfacing with standard CMOS, NMOS, and LSTTL outputs. Consider the operating temperature range and supply voltage requirements to ensure compatibility with the target application environment.

Counter Dividers Part Context

This device belongs to the MC74HC160A series of high-performance silicon-gate CMOS logic products. It shares identical pinouts with LS160 counterparts, ensuring mechanical interchangeability while offering improved performance characteristics typical of the HC logic family. The product line emphasizes low input current and high noise immunity.

Counter Dividers Replacement Considerations

The datasheet confirms the device is pin-compatible with the LS160. Designers should verify electrical parameter alignment, particularly regarding propagation delays and drive capabilities, when substituting between HC and LS logic families in existing circuits.
