Part Details:

HCF40110B DECADE UP/DOWN COUNTER/DECODER/LATCH/DRIVER s SEPARATE CLOCK-UP AND CLOCK-DOWN LINES s CAPABLE OF DRIVING COMMON CATHODE LEDS AND OTHER DISPLAYS DIRECTLY s ALLOWS CASCADING WITHOUT ANY EXTERNAL CIRCUITRY DIP s MAXIMUM INPUT CURRENT OF 1 µA AT 18 V (full package-temperature range) s QUIESCENT CURRENT SPECIFIED UP TO ORDER CODES 20V PACKAGE TUBE T & R s STANDARDIZED, SYMMETRICAL OUTPUT DIP HCF40110BEY CHARACTERISTCS s 5V, 10V AND 15V PARAMETRIC RATINGS s INPUT LEAKAGE CURRENT II = 100nA (MAX) AT VDD = 18V TA = 25°C timing (within 100 ns typ.) of the other clock line. s 100% TESTED FOR QUIESCENT CURRENT The clock signal is fed into the control logic and s MEETS ALL REQUIREMENTS OF JEDEC Johnson counter after it is preconditioned. The JESD13B "STANDARD SPECIFICATIONS outputs of the Johnson counter (which include FOR DESCRIPTION OF B SERIES CMOS anti-lock gating to avoid being locked at an illegal DEVICES" state) are fed into a latch. This data can be feddirectly to the decoder through the latch or can be DESCRIPTION strobed to hold a particular count while the HCF40110B is a monolithic integrated circuit Johnson counter continues to be clocked. The fabricated in Metal Oxide Semiconductor decoder feeds a seven-segment bipolar output technology available in DIP package. driver which can source up to 25mA to drive LEDs HCF40110B is a dual-clocked up/down counter and other displays such as low-voltage with a special preconditioning circuit that allows fluorescent and incandescent lamps. A short the counter to be clocked, via positive going
