Supplied in a 16-TSSOP (4.40 mm width) surface-mount package. The PWR suffix indicates Tape & Reel or Cut Tape delivery — order the reel if you are populating a pick-and-place line, or cut tape for prototype runs. The 0.173" body height fits under low-profile enclosures.
Status is Active per the manufacturer, with ROHS3 compliance.
The CD74HC4511 is a high-speed CMOS version (74HC family) of the classic CD4511 BCD-to-7-segment decoder. The HC version typically draws lower quiescent current (8 µA vs ~80 µA for the CD4511 at 5V) and operates over a wider temperature range (-55°C to 125°C vs -40°C to 85°C for many CD4511 variants). Both are pin-compatible and functionally identical — the HC part is the better choice for battery-powered or extended-temperature designs.
It accepts a 4-bit BCD input (0000 to 1001) and drives the corresponding segments of a common-cathode 7-segment LED display. An internal latch holds the displayed digit when the latch-enable pin is low, so the display stays steady while the microcontroller updates other tasks. The blanking input lets you turn off the display without clearing the latch.
The CD4511BE (PDIP-16) or CD4511BNSR (SO-16) are functionally identical and pin-compatible, but use the older CD4000-series CMOS process — expect higher supply current and a narrower temperature range. For a drop-in surface-mount replacement in the same 74HC family, the CD74HC4511M (SOIC-16) is pin-compatible but in a larger package than the TSSOP-16.
