CD4511BE

The CD4511BE is a CMOS BCD to 7 segment LED latch decoder driver in 16 pin DIP package. It is constructed with CMOS logic and NPN bipolar transistor output devices on a single monolithic structure. This device combines low quiescent power dissipation and high noise immunity features of RCA CMOS with NPN bipolar output transistors capable of sourcing up to 25mA. This capability allows CD4511B to drive LED's and other displays directly. Lamp test, blanking and latch enable or strobe inputs are provided to test display, shut off or intensity modulate and store BCD code. Several different signals may be multiplexed and displayed when external multiplexing circuitry is used.

• High output sourcing capability up to 25mA
• Supply voltage range from 3V to 18V
• Input latches for BCD code storage
• 100% tested for quiescent current at 20V
• Maximum input current of 1µA at 18V (full package temperature range) and 100nA at 18V (25°C)
• 5V, 10V and 15V parametric ratings
• Operating temperature range -55°C to 125°C
