SN74HC393PWR

Counter Dividers Overview

The SN74HC393PWR is a dual 4-bit binary counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -40°C to +85°C. The device features two independent counters, each with direct clear inputs and clock inputs. It provides parallel outputs for each stage, enabling frequency division capabilities up to divide-by-256. The component utilizes a 14-pin TSSOP package.

Counter Dividers Feature Summary

• Dual 4-bit binary counters implemented in a single package
• Direct clear functionality for each individual counter
• Parallel outputs available from every counter stage
• Compatible with LSTTL loads

Counter Dividers Applications

• System timing signal generation
• Frequency division circuits
• N-bit binary counter expansion

Counter Dividers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP package type during procurement. Confirm RoHS compliance status and lead finish details via the manufacturer's current packaging addendum. Ensure the moisture sensitivity level rating aligns with assembly requirements. Cross-reference the active production status against the latest orderable part number list.

Counter Dividers Selection Notes

Select this component when space-constrained designs require two separate 4-bit counters. The HC logic family offers low power consumption suitable for battery-operated systems. Verify that the input transition rise/fall times meet the recommended operating conditions to prevent incorrect state transitions. Ensure the load capacitance does not exceed specified limits for optimal switching performance.

Counter Dividers Part Context

This device belongs to the SNx4HC393 series of dual 4-bit binary counters. It shares functional similarities with other members of the 74HC family but is distinguished by its internal architecture containing eight flip-flops and additional gating. The PWR suffix specifically denotes the Thin-Shrink Small Outline Package (TSSOP) variant.
