SN74HC393DBR

Counter Dividers Overview

The SN74HC393DBR 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 system timing signals and can drive up to 10 LSTTL loads. The typical propagation delay is 13ns, with maximum clock frequencies reaching 36MHz at 6V.

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-14 package with tape and reel packaging containing 2000 units per carrier. Confirm RoHS compliance and lead finish specifications (NIPDAU) match project requirements. Ensure the moisture sensitivity level rating aligns with assembly process capabilities.

Counter Dividers Selection Notes

Select this component when space efficiency is critical due to its ability to house two counters in one package. Consider the HC logic family characteristics regarding power consumption and speed. Verify that the input transition rise/fall times meet the recommended operating conditions to prevent incorrect state transitions.

Counter Dividers Part Context

This part belongs to the SNx4HC393 series of dual 4-bit binary counters. It utilizes the HC logic family technology, offering low power consumption and high noise immunity compared to older logic families. The device is designed for general-purpose digital counting and timing applications.
