Counter Dividers datasheet and documents for QS74FCT191CTSI

QS74FCT191CTSI

Counter Dividers Overview

The QS74FCT191CTSI is a high-speed synchronous 4-bit binary up/down counter manufactured by Quality Semiconductor. It features an integrated clock oscillator and supports asynchronous parallel loading. The device operates within a supply voltage range of 4.75 V to 5.25 V and functions reliably across an industrial temperature range from -40 °C to +85 °C. Packaged in a 20-pin ceramic quad flatpack (QCCN/LCC20), it utilizes CMOS technology for efficient performance.

Counter Dividers Feature Summary

Integrated clock oscillator eliminates external timing components
Synchronous 4-bit bidirectional counting capability
Asynchronous parallel load input for immediate data preset

Counter Dividers Applications

High-speed digital timing circuits
Frequency division systems
Digital control logic requiring precise count synchronization

Counter Dividers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor Inc, distinct from Texas Instruments variants. Confirm the package type is QCCN-20 with ceramic construction. Ensure the operating temperature range meets industrial standards (-40°C to +85°C). Cross-reference datasheets for specific electrical characteristics and pinout configurations before integration.

Counter Dividers Selection Notes

Select this component when an internal clock source is required to simplify board layout. The synchronous design ensures stable counting edges. Verify compatibility with 5V logic families. Consider the hermetic ceramic package if environmental robustness is critical compared to plastic alternatives.

Counter Dividers Part Context

This part belongs to the FCT logic series, designed for fast CMOS operation. It serves as a specialized counter within Quality Semiconductor's portfolio, offering integrated oscillation features not present in standard binary counters. It complements other FCT devices like decoders and multiplexers in complex digital systems.
