SN74HC193QPWRG4Q1

Counter Dividers Overview

The SN74HC193QPWRG4Q1 is a Texas Instruments automotive-grade, 4-bit synchronous up/down binary counter from the HC logic family. It features dual independent clock inputs for separate up and down counting operations and includes an asynchronous clear function. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum frequency of 14 MHz at nominal supply. It is housed in a 16-pin TSSOP package and is qualified under AEC-Q100 standards for operation across an extended temperature range of -40°C to +125°C.

Counter Dividers Feature Summary

• Dual independent clock inputs enable simultaneous or distinct up and down counting sequences without interference.
• Asynchronous clear input allows immediate resetting of all counter outputs regardless of clock state.
• AEC-Q100 qualification ensures reliability and performance consistency for demanding automotive electronic environments.

Counter Dividers Applications

• Automotive digital timing circuits requiring precise bidirectional count control
• Vehicle instrumentation systems utilizing synchronous binary counting
• Embedded automotive controllers managing sequential operational states

Counter Dividers Procurement Notes

Verify the complete part number including suffixes to confirm specific packaging options such as tape and reel configurations. Ensure the procurement channel sources directly from authorized distributors to guarantee AEC-Q100 certification integrity. Confirm that the delivered components match the specified 16-TSSOP physical dimensions and pinout requirements for your target PCB layout.

Counter Dividers Selection Notes

Select this component when designing automotive logic circuits that require synchronous bidirectional counting capabilities with high noise immunity. The HC series offers standard CMOS performance suitable for general-purpose digital applications. Consider the 16-TSSOP package constraints regarding thermal dissipation and board space availability during the initial schematic capture phase.

Counter Dividers Part Context

This device belongs to the SN74HC193-Q1 family of automotive catalog counters. It serves as a specialized variant designed specifically for vehicle electronics, differing from commercial counterparts through rigorous qualification testing. The Q1 designation indicates compliance with automotive reliability standards, ensuring suitability for under-hood and safety-critical system implementations.

Counter Dividers Replacement Considerations

SN74HC193NSR is a compatible alternative offering identical logical functionality but lacks automotive qualification and operates within a limited temperature range of -40°C to +85°C.
