SN74HC393PWT

Overview

The SN74HC393PWT 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 of -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 up to divide-by-256. The component utilizes a 14-pin TSSOP package.
