CD74HCT4511EG4

Display Drivers Overview

The CD74HCT4511EG4 is a high-speed CMOS BCD-to-7-segment latch/decoder/driver manufactured by Texas Instruments. It accepts four-bit binary-coded decimal inputs and drives seven-segment displays. The device operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 60 ns. It supports an operating temperature range from -55°C to +125°C. The component is housed in a 16-pin Dual In-Line Package (DIP) with a pin pitch of 0.300 inches (7.62 mm). It includes internal pull-up resistors for the outputs.

Display Drivers Feature Summary

• Converts 4-bit BCD input into active-high signals for driving seven-segment LED displays
• Includes a latch control input to hold the displayed data independent of input changes
• Features internal output pull-up resistors eliminating external components
• Provides blanking input functionality to suppress display segments

Display Drivers Applications

• Seven-segment LED numeric display systems
• Digital counter readout interfaces
• Industrial control panel indicators
• Consumer electronic device displays

Display Drivers Procurement Notes

Verify the package type matches the required 16-DIP form factor. Confirm the logic family is HCT for compatibility with TTL-level inputs. Check RoHS compliance status as manufacturing sources may vary. Ensure the supplier provides original manufacturer documentation. Validate the part number suffix EG4 indicates lead-free and tape/reel or tube packaging specifics if required by assembly processes.

Display Drivers Selection Notes

Select this component when interfacing microcontrollers or logic circuits with seven-segment displays requiring direct drive capability. The HCT series ensures compatibility with standard 5V TTL logic levels. Consider the wide operating temperature range for industrial environments. Verify that the current drive capability meets the specific LED segment requirements without additional buffering.

Display Drivers Part Context

This device belongs to the Texas Instruments 74HC/HCT logic family, designed for high-speed digital applications. The CD74HCT4511 variant specifically targets BCD decoding tasks. It is part of a broader ecosystem of compatible decoders and drivers. The EG4 suffix typically denotes environmental compliance and specific packaging configurations offered by the manufacturer.

Display Drivers Replacement Considerations

Compatible substitutes include the CD74HC4511M96E4 for HC logic level compatibility and the SN74LS48N for LS TTL alternatives. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement part supports the same DIP-16 package configuration.
