74192PC

Overview

The Fairchild Semiconductor 74192PC is a synchronous, bidirectional decade counter housed in a 16-pin DIP package. It features independent up and down clock inputs for flexible counting control. The device includes dedicated load and reset pins to manage data entry and initialization states directly. Designed for TTL logic compatibility, it supports parallel data loading and continuous counting operations within standard industrial temperature ranges.

Feature Summary

• Synchronous bidirectional decade counting capability with independent clock inputs
• Parallel data loading functionality via dedicated load pin
• Direct asynchronous reset input for immediate state clearing

Applications

• Digital frequency division circuits
• Sequential event timing controllers
• Decimal digit generation in digital displays

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature range. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the ordering code with official distributor catalogs to confirm availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a synchronous decade counter with parallel load capability is required. It is suitable for designs needing independent up/down control without external decoding logic. Consider the 16-pin DIP package for through-hole prototyping or legacy board compatibility where space constraints are minimal.

Part Context

This part belongs to the 74192 family of synchronous counters. It differs from non-synchronous counterparts by requiring a clock signal for state transitions. The device integrates decade decoding internally, eliminating the need for external BCD-to-decimal conversion logic in display applications.
