HCC/HCF4511B

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
* All voltages are with respect to VSS (GND).

The HCC/HCF4511B (HCC4511B (extended temperature range) and the HCF 4511B (intermediate temperature range) )are monolithic integrated circuits available in 16-lead dual in-line plastic or ceramic package and plastic micro package.

The HCC/HCF4511B types are BCD-to-7-segment latch decoder drivers constructed with COS/MOS logic and n-p-n bipolar transistor output devices on a singlemonolithic structure. These devices combine the low quiescent power dissipation and high noise immunity features of COS/MOS with n-p-n bipolar output transistors capable of sourcing up to 25 mA. This capability allows the HCC/HCF 4511B types to drive LED's and other displays directly.

Lamp Test (LT), Blanking (BL), and Latch Enable or Strobe inputs are provided to test the display, shut off or intensity-modulate it, and store or strobe a BCD code, respectively. Several different signal of HCC/HCF4511B may be multiplexed and displayed when external multiplexing circuitry is used.
