74HC193DB-Q100J

Counter Dividers Overview

The Nexperia 74HC193DB-Q100J is a presettable synchronous 4-bit binary up/down counter. It features separate count-up (CPU) and count-down (CPD) clock inputs, asynchronous parallel load (PL), and master reset (MR). The device operates with a supply voltage range of 2.0 V to 6.0 V. It includes terminal count outputs (TCU and TCD) for cascading. Qualified to AEC-Q100 Grade 1 standards, it supports ambient temperatures from -40 °C to +125 °C.

Counter Dividers Feature Summary

• Automotive qualified in accordance with AEC-Q100 Grade 1
• Synchronous reversible 4-bit binary counting with separate clocks
• Asynchronous parallel load and master reset capabilities
• Expandable without external logic via terminal count outputs

Counter Dividers Applications

• Automotive electronic systems requiring reliable counting functions
• Multistage counter configurations using cascaded terminal count outputs
• Digital timing and sequencing circuits in mixed-voltage environments

Counter Dividers Procurement Notes

Verify the specific package variant against the ordering information table. The suffix 'DB' indicates an SO16 plastic small outline package (SOT109-1). Confirm that the design requires the HC logic family input levels rather than HCT TTL levels. Ensure the application environment stays within the specified temperature and voltage limits defined in the recommended operating conditions.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit up/down counter with independent clock inputs is required. The HC series offers CMOS input levels suitable for standard logic interfaces. Consider the HCT variant if direct interfacing with TTL logic levels is necessary. Verify that the SO16 package dimensions fit the PCB layout constraints and thermal requirements.

Counter Dividers Part Context

This part belongs to the Nexperia 74HC193-Q100 and 74HCT193-Q100 product family. These are presettable synchronous 4-bit binary up/down counters designed for automotive applications. The family provides options for different logic families (HC and HCT) and various surface-mount packages including SO16 and TSSOP16.

Counter Dividers Replacement Considerations

The datasheet revision history notes that the SSOP16 package variants (74HC193DB-Q100 and 74HCT193DB-Q100 in SOT338-1) were removed in version 2. Designers should ensure they do not specify obsolete package types.
