Product Overview: CD74HC4511PWTE4

The CD74HC4511PWTE4 is a high-performance, CMOS logic BCD-to-7-segment latch/decoder/driver designed and manufactured by Texas Instruments. This integrated circuit is specifically tailored for driving common-cathode 7-segment displays with ease and efficiency. It is a vital component in digital systems where numeric output display is required, such as in calculators, digital clocks, measuring instruments, and other electronic devices that require numerical visualization.

Key Features

• BCD-to-7-Segment Decoder: The chip decodes BCD (Binary-Coded Decimal) inputs to control the display of the numerals 0-9 on a 7-segment display.
• Latch Functionality: It includes latching functions that allow the display to retain the current digit until the next one is provided, ensuring stable and flicker-free numeric representation.
• High-Output Drive: The CD74HC4511PWTE4 is capable of sourcing or sinking up to 25mA at 4.5V, making it suitable for directly driving LEDs in a 7-segment display.
• High Noise Immunity: Characteristic of CMOS devices, this product boasts a high level of noise immunity, providing reliable performance in electrically noisy environments.
• Wide Operating Voltage: It operates over a wide voltage range from 2V to 6V, accommodating various application requirements and power supplies.

Package and Quality

The device comes in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, referred to by the suffix 'PW'. The 'E4' suffix indicates that it adheres to Texas Instruments' lead-free standards, making it suitable for use in environmentally sensitive applications and in jurisdictions with strict regulations on hazardous substances.
