CD74HC4511PWR

Display Drivers Overview

The CD74HC4511PWR is a high-speed CMOS BCD-to-7-segment latch/decoder/driver manufactured by Texas Instruments. It features a 16-pin TSSOP package and operates within a supply voltage range of 2 V to 6 V. The device converts four-bit binary-coded decimal inputs into seven-segment outputs for LED displays, with a propagation delay of 60 ns. It supports an operating temperature range from -55°C to +125°C and includes internal pull-up resistors on the outputs.

Display Drivers Feature Summary

• Converts 4-bit BCD input signals directly to 7-segment display outputs
• Includes internal output pull-up resistors for direct LED driving
• Features latch functionality to hold display data stable during input transitions

Display Drivers Applications

• Seven-segment LED numeric display systems
• Digital counter readout interfaces
• Microcontroller-based indicator panels

Display Drivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documentation matching the Texas Instruments manufacturing lot codes.

Display Drivers Selection Notes

Select this component when a latch function is required to maintain display stability without continuous microcontroller polling. The HC series offers higher speed than legacy LS logic while maintaining low power consumption. Verify that the 60 ns propagation delay meets the timing constraints of your system clock frequency.

Display Drivers Part Context

This part belongs to the Texas Instruments CD74HC4511 family, which are standard BCD-to-7-segment decoders. The PWR suffix specifically denotes the surface-mount TSSOP-16 packaging variant. It is functionally compatible with other 74HC4511 devices from different manufacturers adhering to the same pinout and electrical specifications.
